HYDROELECTRIC POWER AND PIPE TURBINE GENERATION SYSTEM
FIELD OF THE INVENTION:
The present invention concerns a power generation system and relates, mainly, to a system created to generate electrical energy from the potential energy existing in a hydraulic load.
BACKGROUND OF THE INVENTION:
The demand for energy from renewable sources is increasing as the earth's fossil fuels are depleted. In addition, it is desirable to generate electricity from clean energy sources that do not contribute to global warming.
A common renewable energy source is hydroelectric power, which is generated by harnessing the potential of a hydraulic load, such as water. A typical hydroelectric power generation system requires a water source, such as a river, that must be dammed high to create a hydraulic load with stored potential energy. A pipe runs from the dam to a lower location. A turbine generator is installed at the end of the pipeline, so that the water that leaves the high place passes through the turbine. The water drives the turbine, which in turn drives an electric generator that generates electricity.
The problem with the dam system for hydroelectric power generation is that the flood caused by the dam has a negative impact on the local environment. The flood destroys the natural landscape and causes people who live around the area to move to other areas.
To avoid problems associated with this type of hydroelectric power generation, an alternative system uses a pipe that drains water from a high point
Petition 870160013391, of 11/04/2016, p. 10/92
2/23 to a lower point. A turbine is installed in the pipeline so that it is driven by the water that passes through the pipeline.
Whenever necessary, a spillway can be used and, from there, water can be taken to the turbine through a pipe.
Alternative turbine installation methods, in addition to the method already mentioned above, use a modular structure in which the turbines are installed.
Siphon-type systems for hydroelectric power generation are generally more used for hydroelectric power generation in small or micro quantities, which normally generates electricity from a lower hydraulic load, unlike the dam system. In the generation of hydroelectric power of the siphon type, the pipe can be installed next to a waterfall, river, channel or stream where there is a naturally available hydraulic load. The pipeline carries a flow of water along with the existing flow, causing the least possible impact on the environment.
A problem with these systems is that it is necessary to remove the turbine from the pipeline to perform maintenance. This operation can be difficult to perform and expensive, since the turbines are usually installed in a pipeline located on a steep slope that is difficult to access. Another problem is that it is generally difficult to optimize the generation of electrical energy, as the efficiency of a conventional turbine varies according to the variation of the water flow that drives the turbine.
The present invention seeks to provide an improved power generation system.
OBJECTS OF THE INVENTION:
Some of the objectives of the present study, which are accomplished by at least one configuration described here, are the following:
Petition 870160013391, of 11/04/2016, p. 11/92
3/23
An objective of the present study is to provide a simple, compact and modular turbine and a hydroelectric power generation system that presents excellent energy efficiency.
One objective of the present study is to provide a hydroelectric and turbine power generation system in pipes that can be adapted to different hydraulic conditions and heights of falls.
Another objective of the present study is to provide a unidirectional and highly efficient hydroelectric turbine adapted to generate energy using potential energy from, but not limited to, falls in channels, river course designs, hydraulic channels for hydroelectric plants, pipeline lines discharges from ETP (Effluent Treatment Station) / STP (Sewage Treatment Station).
Another objective of the present study is to provide a pipeline and unidirectional turbine and a hydroelectric power generation system that has only one moving part (rotor), making it easier to maintain and install the system, without the need for specialized devices.
Another objective of the present study is to provide a hydro potential turbine generator that has one or more turbine blades to improve the efficiency and performance of the generator.
Another objective of the present study is to provide a generator system full of turbines that has several unidirectional turbine generators connected to an onshore and offshore electrical distribution system.
Another objective of the present invention is to provide hydroelectric power generation equipment that is easier to install and maintain due to its light weight. The materials used for this device are metals, not metals, preferably composite materials and, more specifically, plastic reinforced with
Petition 870160013391, of 11/04/2016, p. 12/92
4/23 fiber (FRP) or glass reinforced plastic (GRP), which make the equipment anticorrosive and adaptable to any type of fluid for power generation.
Another objective of the present study is to provide a pipeline turbine that can be installed, preferably, using an open channel and / or siphon method to generate energy adapted to a variety of drop heights that involve the least possible construction.
Another objective of the present study is to provide a generator system filled with turbines connected in series or parallel to the water body. Serial installation is the preferred method in high drop applications to use the available drop. The turbine is adapted to operate on high, medium, low and ultra low falls (from 1 to 200 m).
Another objective of the present invention is to provide a bypass system for the turbine-filled generator system to ensure that power is generated in the event of a failure in any turbine unit.
Yet another objective of the present study is to provide a hydroelectric power generating unit that can be installed underwater, underground and that fits into existing pipes, since there are no components external to the turbine unit. In this way, the results would be minimal land acquisition, minimal environmental impact, no deviations or barriers created, in addition to zero deforestation and rehabilitation.
These objectives and other advantages of the present study will be more evident with the following description.

At the second open end there is a cross-sectional area substantially equal to the cross-sectional area of the pipe.
The system also features an open-ended tapered outlet component that has the first end installed in the fluid outlet of the housing and the second end positioned downstream of the fluid outlet. At the second open end there is a cross-sectional area substantially equal to the cross-sectional area of the pipe.
The axis is fixed according to the housing, so that the axis does not rotate in relation to the housing.
The turbine rotor is installed rotatably on the shaft using a set of bearings provided on the turbine rotor. The shaft is installed rotatably in the housing by at least one set of bearings provided in the housing.

DETAILED DESCRIPTION OF PREFERENTIAL SETTINGS:
The present invention can be better understood with the description documented here. In order to achieve the objectives set out above and in accordance with the purpose of the invention, and to overcome the problems and deficiencies associated with the previous illustration, a variety of configurations are described. However, those who understand the illustration may notice that the detailed description provided here is for didactic purposes only and can be configured in several ways, as the invention goes beyond these limited configurations. Therefore, the specific details contained herein should not be construed as limiting, but as a basis for the claims and as a representative basis for teaching those who understand the illustrations to use the invention in virtually any suitably detailed system, structure or matter.
Referring initially to figures 1 and 2 of the attached illustrations, a power generation system 1 of a configuration of the invention is installed in the turbine housing 2, configured to be connected in line to a part of
Petition 870160013391, of 11/04/2016, p. 18/92
10/23 a pipe. The power generation system of a configuration of the invention can therefore be used as a pipe power generation system. The system includes a casing or housing for the generator 3 that houses, at least partially, the components of the system. The housing of generator 3 is described in more detail below.
In one configuration, the power generation system of a configuration of the invention is integrated into a part of a pipe which is provided with mounting flanges at each end. In this configuration, the pipe part can be installed in line with an existing pipe.
The electric power generation system 1 consists of an elongated shaft 4 that extends through the generator housing 3. When the electric power generation system 1 is installed in the turbine housing 2, the geometric axis of the mechanical axis 4 is substantially parallel to the direction of flow flow through the turbine housing 2, as indicated by the arrow 5 in figures 1 and 2.
In this configuration, axis 4 is fixed to the generator housing 3, so that axis 4 does not rotate in relation to the generator housing 3. However, in other configurations, axis 4 is rotatably installed in the generator housing 3 by a set of bearings provided on the shaft 4 and in the generator housing 3.
The turbine rotor 6 is installed on the shaft 4. In this configuration, the turbine rotor 6 is installed rotationally on the shaft 4 by means of a bearing set 7 provided on the turbine rotor 6. In this configuration, the turbine rotor 6 and the bearing set 7 are the only components of the system that rotate in operation. This minimizes the number of system components that are subject to wear and tear during use.
Providing a single bearing set 7 on the turbine rotor 6 allows for easy maintenance of the bearing set compared to other conventional systems that require multiple bearing sets positioned to provide rotary support for the shaft and rotor.
Petition 870160013391, of 11/04/2016, p. 19/92
11/23
In other configurations, where the axis 4 is rotatably installed in the generator housing 3, the turbine rotor 6 is fixed to the axis 4 so that there is rotation with the axis 4.
Referring to figure 3 of the attached illustrations, the turbine rotor 6 consists of a central hub 8 that is provided with a mounting hole 9. The bearing set 7 is located in part of the mounting hole 9. The shaft 4 is extends along the bearing set 7 and the mounting hole 9 to rotatively install the turbine rotor 6 on the shaft 4.
The turbine rotor 6 consists of three rotor vanes 10 which are each connected to the central hub 8 at an angle relative to each other. In this configuration, there are three rotor vanes 10, but in other configurations, there is only one rotor van or more than three. The vanes of the rotor 10 are positioned at such an angle that the fluid that passes through the turbine housing 2 acts on the vanes
10. They, in turn, exert a rotational force on hub 8 that rotates the turbine rotor around the geometric axis of axis 4.
The turbine rotor 6 is made up of a generally cylindrical outer ring member 11 that partially surrounds the vanes 10. The outer ring 11 incorporates at least one permanent magnet 12, which is installed or molded integrally with the outer ring 11. In this configuration, the outer ring 11 has several permanent magnets 12 which are located in spaced positions around the outer ring 11, as shown in figure 3. In one configuration, the permanent magnets 12 are partially or, preferably, fully integrated with the outer rotor ring turbine. Permanent magnets are also preferably encapsulated.
In this configuration, a generally cylindrical adapter ring 11a is provided between the outer ring 11 and the permanent magnets 12. The adapter ring 11a is an optional component that facilitates the assembly and disassembly of the generator. For example, the dimensions of the adapter ring 11a can be adjusted during the development process to compensate for design changes made to the dimensions of the outer ring 11, the permanent magnets 12 or the generator stator (13 and / or 14), without the need to change the dimensions of the rotor.
Petition 870160013391, of 11/04/2016, p. 20/92
12/23
The permanent magnets 12 rotate together with the turbine rotor 6. The permanent magnets 12 form a part of the power generation set. The permanent magnets 12 and the outer ring 11 act as an electric generator rotor. The electric generator rotor is integrated with the turbine rotor due to the connection of the outer ring to the hub 8 by means of the blades 10. The turbine rotor 6 is therefore integrated with an electric generator rotor of an electric power generation set. .
In the preferred configuration of the invention, the turbine rotor 6 is composed of stamping that provide grooves in which the magnets 12 are supported. The grooves are dimensioned so that there is enough space around the magnets 12 to receive an insulating material. The space in the grooves is filled by the insulating material, which covers the magnets, protecting them from wear and tear, as well as to avoid contact with water. Encapsulation also helps to prevent magnets from separating from the stamping to which they are attached when rotating at high speed.
The turbine rotor 6 is preferably molded with the vanes 10 and the outer ring 11 forming a single integrated component. In other configurations, hub 8, vanes 10 and outer ring 11 are molded separately and fixed to each other by welding.
The integration between the electric generator rotor and the turbine of a configuration of the invention avoids the need for transmission assemblies, such as flywheels or gearboxes that are conventionally used to couple the turbine rotor to an electric generator rotor. The integration between the electric generator rotor and the turbine of the configuration of the invention is, therefore, less complex and easier to maintain than conventional assemblies that require a transmission mechanism.
In relation to figure 4 of the attached illustrations, a generator 13 stator element is installed in the generator housing 3 to partially surround the turbine rotor
6. The diameter of the internal opening of the generator stator 13 is selected so that there is a smaller gap between the stator 13 and the rotor 6 on the fluid inlet side of the assembly, compared to the fluid outlet side. This minimizes the possibility of particles entering the space between the surface of the turbine rotor
Petition 870160013391, of 11/04/2016, p. 21/92
13/23 and the housing surface that protect the generator from impacts and from obstructions in rotation due to mud, sand and dirt.
At least one winding is installed in the generator stator 13 which is fixed according to the generator housing 3. In this configuration, several windings 14 are positioned spaced around the generator stator 13. The windings 14 form a second part of the set of power generation.
In use, when the turbine rotor 6 rotates, the turbine rotor 6 moves the magnets 14 along the adjacent windings 14, which induces a tension in the windings 14. The voltage is extracted from the windings 14 and supplied via an electrical connection , to the rest of the system (not shown). The rest of the system regulates the energy generated and produces energy from the system. The rest of the system preferably also allows for condition monitoring, remote monitoring and optional power control.
In a preferred embodiment of the invention, the generator rotor 6 and the generator stator 13 are encapsulated in an insulating material that is resistant to water. The water that passes through the electric generator set comes into contact with the encapsulated rotor 6 and stator 13 and cools them. This avoids the need for forced cooling, which simplifies the system, reduces the overall cost and reduces the need for maintenance.
In this configuration, a portion of non-permanent magnetized metal 15 is provided between each permanent magnet 12, as shown in the assembly illustrated schematically in figure 5. The permanent magnets 12 and the intercalated portions of non-permanent magnetized metals 15 together form a rotor of poles. Magnetism is induced in the metal portions 15 so that they act as magnets within the electrical power generation system. This pole allows the number of permanent magnets 12 to be reduced, reducing the total cost of the system.
The grooves in the generator rotor and / or stator are preferably angled so that each groove is at an angle to the axis of rotation. The angular location of one end of each groove must be offset from the other end. Tilt can be achieved during manufacturing by rotating and
Petition 870160013391, of 11/04/2016, p. 22/92
14/23 compensate the laminations with respect to each other, so that the passages formed by the overlapping grooves of the laminations have a helical shape. The slope helps to reduce magnetic noise and prevent obstructions (a tendency for the rotor to lock).
In other configurations, the position of the magnets and windings in the power generation set is reversed: the windings are integrated in the turbine rotor and the magnets are integrated in the stator. In one configuration, the windings are provided on the rotor and stator. In another configuration, the generator set has an induction generator that is coupled to the turbine rotor.
In relation to figure 6 of the attached illustrations, this configuration of the invention is provided with an input guide vane assembly 16. The input guide vane assembly 16 has a central hub 17 that is fixed according to the generator housing 3. Several blades of the inlet guide 18 extend radially out of the central hub 17 in spaced positions. The vanes of the inlet guide 18 are positioned at an angle to each other to change the direction of fluid flow through the system. The vanes of the inlet guide 18 direct the flow of the fluid in the direction that it partially coincides with the plane of one or more vanes 10 of the turbine rotor 6. The vanes of the inlet guide 18 maximize the efficiency of the energy transfer from the fluid to the the turbine rotor 6, minimizing turbulence at the front edge of the rotor vanes 10.
The vanes of the inlet guide 18 are partially encased by the walls of the fluid inlet tube 19 which aligns with a fluid inlet in the generator housing 3 through which the fluid passes to the power generation system 1. In this configuration, the transverse area of the fluid inlet opening of the power generation system 1 is smaller than the transverse area of the portion of the turbine housing 2.
Referring to figure 7 of the attached illustrations, a permanent output vane set 20 has a central hub 21 which is fixed according to the
Petition 870160013391, of 11/04/2016, p. 23/92
15/23 generator housing 3, adjacent to an outlet of the generator housing 3. Permanent outlet vanes 22 extend radially out of the permanent hub 21. The plane of each of the permanent vanes 22 is substantially parallel to the direction of flow 5 of the fluid that passes through the system. An external support component 20 extends around the permanent vanes 22 and provides a fluid outlet that aligns with a fluid outlet in the generator housing 3. The transverse area of the fluid outlet opening is smaller than the transverse area the turbine housing portion 2.
The function of the permanent outlet assembly 20 is to provide lateral support to the axis 4, which is maintained within the permanent hub 21. The alignment of the planes of the permanent vanes 22 provides minimal resistance to the flow of the fluid out of the system.
In this configuration, the vane guide assembly 16 and the permanent output assembly 20 support the ends of shaft 4.
With reference to figure 8 of the attached illustrations, in a configuration of the invention, the generator housing 3 is composed of a first housing part 24 and a second housing part 25 which are fixed to each other, so that they can be separated later , by fixings 26. The first and second portions 24, 25 come into contact in a separation plane 27 which is substantially parallel to the direction of flow 5 of the fluid passing through the system.
With reference to figure 9 of the attached illustrations, the two portions 24, 25 of the generator housing 3 are configured to be separated from each other by releasing the fixings 26. The first portion 24 that forms half of the generator housing 3 in this configuration can, therefore, be partially raised to allow access to the rotor and other components of the generator housing 3 so that the maintenance of the components can be done easily. In this way, maintenance can take place while the power generation system is installed on site. This prevents the entire power generation system from having to be removed from the pipeline for maintenance to be performed, and therefore, this increases the ease of repair and reduces the overall cost.
Petition 870160013391, of 11/04/2016, p. 24/92
16/23
In relation to figure 10 of the attached illustrations, in another configuration of the invention, the generator housing 3 has the first and second portions 24, 25 which are fixed to each other, so that they can be separated later, in plane 28, which it is vertical and substantially perpendicular to the direction of flow 5 of the fluid passing through the system. In this configuration, the generator housing 3 can be divided along the plane 28 into two separate portions 24, 25 to allow maintenance of the components within the generator housing 3.
Back to figures 1,2 and 11 of the attached illustrations, in a preferred configuration of the invention, the system has a venturi inlet passage 29 that connects with the generator housing 3 in relation to the fluid communication. In this configuration, the internal surface of the Venturi inlet passage 29 is generally tapered, with a second open end 30 having a larger cross section than the first open end 31.
The second open end has a transverse area substantially equal to the transverse area of the portion of the turbine housing 2. The first open end has a transverse area substantially equal to the transverse area of the fluid inlet of the generator housing 3.
The Venturi inlet passage 29 effectively reduces the diameter of the passage through which the fluid passes as it approaches the electricity generation system. As the diameter of the passage decreases, the speed of the flow that passes through it increases. The Venturi effect in the passage, therefore, serves to increase the flow speed to a speed that is greater than the flow that passes through any other place in the pipeline. The increased speed allows additional mechanical energy to be extracted from the fluid, maximizing the speed of rotation of the turbine rotor which, in turn, increases the energy production of the generator.
In this configuration, the system incorporates an outlet suction tube 32 which is connected to the fluid outlet of the generator housing 3. The suction tube has an internal surface that is hollow and has a substantially tapered shape. The suction tube 32 has a first open end 33 which is
Petition 870160013391, of 11/04/2016, p. 25/92
17/23 connected to the fluid outlet of the generator housing 3. The first open end 33 of the suction tube 32 has a cross-sectional area substantially equal to the cross-sectional area of the fluid outlet of the generator-housing 3.
The suction tube 32 has a second open end 34 that has a larger cross-sectional area than the first open end 33. The cross-sectional area of the second open end 34 is substantially the same as the cross-sectional area of the turbine housing end 2. The suction tube 32 allows the fluid to exit the power generation system with ease by withdrawing the fluid from the generator housing 3 as a result of the differential pressure created by the suction tube 32 within the pipeline.
In one configuration, the Venturi inlet passage 29 and the suction tube 32 are molded with the generator housing 3. However, in other configurations, the Venturi inlet passage 29 and / or the suction tube 32 are separable components that , in turn, are connected to the generator housing 3.
With reference to figure 12 of the attached illustrations, a power generation system 1 of a configuration of the invention is installed in the turbine housing 2 of a pipe 35. The energy generation system 1 and the pipe 35 are arranged in a generation of hydroelectric energy of the siphon type. This type of system is a small or micro hydroelectric power generation system. The piping can, for example, be installed at one end at the base of a silting tank or spillway. The power generation system of a configuration of the invention is designed to work with high, medium, low and ultra-low drops from 1 meter to at least 200 meters.
One end of tubing 35 is submerged in a body of water 36 at a first location. The other end of tubing 35 is submerged in a body of water 37 in a second location, which is lower than the first. Piping 35 incorporates an outlet 38 which is configured to be connected to a pump. The pump can therefore be connected to outlet 38 to pump air out of the tubing 35 in order to create a negative pressure within the tubing. This causes the water body 36 to be sucked into the pipe 35 where the water can
Petition 870160013391, of 11/04/2016, p. 26/92
18/23 flow through the pipe 35 to the lowest location, thus initiating the siphon action in the pipe 35.
As the water is sucked into the pipe 35 by the siphon effect, the water acts on the vanes 10 of the turbine rotor 6 to rotate the turbine rotor 6. The rotation of the turbine rotor 6 rotates the generator rotor of the generator set, producing energy electrical.
With reference to figure 13 of the attached illustrations, in a configuration, a variety of power generation systems of configurations of the invention can be installed in series with each other and spaced from each other along a pipe. In this configuration, three power generation systems 39-41 are connected in series in a pipe 42.
Piping 42 sucks water from the water body 43 at an elevated location and takes the water to a lower location 44. The power generation systems 30-41 are positioned in progressively lower positions in relation to the water drop 43, so that the potential energy of water flowing from the elevated body of water 43 is divided between the power generation systems 39-41. For example, in one configuration, five turbines that are calculated for a drop of 20 meters can be connected in series and at an interval of 20 meters each to divide a total fluid drop of 100 meters between the turbines.
A 45-47 bypass or piping is provided in parallel with each 30-41 electrical generation system. Each of the 45-47 bypass pipes incorporates inlet and outlet shut-off valves that can be operated to open or close each of the 45-47 bypass pipes. The shut-off valves can be opened or closed progressively to adjust the flow of water that passes through the bypass pipe 45-47 and, therefore, through the respective power generation systems 30-41. The shut-off valves are also preferably adjustable to vary the amount of water that passes through each bypass pipe in order to reduce the pressure of the water drop that passes through the turbine.
Petition 870160013391, of 11/04/2016, p. 27/92
19/23
If one of the 39-41 power generation systems needs maintenance, the shut-off valves at each end of the system can be closed to prevent water flow from entering or leaving the generation system. The shut-off valves in the respective bypass piping can be adjusted to allow the flow to pass through the bypass piping at a flow rate similar to the flow rate of the existing fluid when the power generation system is connected and operating correctly.
Bypass lines 45-47 and shut-off valves allow the water flow through pipe 42 and the 3941 power generation system to be adjusted to maximize power generation, even when one or more power generation systems electrical power are in maintenance.
It should be noted that in one of the configurations of the invention, a pipe can incorporate only one or more than three systems for generating electricity.
In a series connected series, as shown in figure 13, it is possible to have partial power generation if one or more turbines fail, since other turbines in the set can still function. If one or more turbines fail, water can be diverted through the bypass piping around each failed turbine. The series set can also be adapted if there is a drop variation to allow partial generation of energy by matching the number of operational turbines with the number of available drops.
With respect to figure 14 of the attached illustrations, in another configuration of the invention, three electrical power generation systems 48-50 are installed in three respective pipes 51-53, in parallel with each other. This parallel configuration of the power generation systems allows one or more 48-50 power generation systems to be turned on or off to vary the power generation capacity to match the available water flow. In other configurations, several electrical power generation systems are installed in parallel with each other, and in these configurations, there are less than three or more than three power generation systems.
Petition 870160013391, of 11/04/2016, p. 28/92
20/23
In a set connected in parallel, as shown in figure 14, partial generation can continue to exist if the flow varies, as long as an adequate number of turbines corresponding to the reduction in flow can be kept in operation.
Assemblies connected in parallel or in series solve the problem that occurs with conventional systems, where only one turbine or a small number of turbines are used and where a failure in any of these components significantly reduces or completely interrupts the power generation capacity . Invention configurations allow power generation to continue, even when the drop falls below a level that would cause a conventional assembly to stop working.
With reference to figure 15 of the accompanying illustrations, another embodiment of the invention incorporates many of the same components described above. Corresponding reference numbers are used to combine the appropriate components of each configuration.
In this configuration, a power generation system 54 includes two turbine rotors 55, 56 which are similar to the single turbine rotor 6 of the configuration described above. However, in this configuration, the first and second turbine rotors 55, 56 are attached to axis 4 and axis 4 is rotationally attached to the generator housing
3. The first and second turbine rotors 55, 56 rotate together with axis 4 in sync. However, in other embodiments of the invention, axis 4 is attached to the housing of the generator 3 and each of the turbine rotors 55, 56 is rotatably attached to the fixed axis 4.
The power generation system 54 of this configuration works in a similar way to the configurations described above: the power generation set associated with each turbine rotor 55, 56 generates electricity as the turbine rotor 55, 56 rotates. However, in this configuration, the potential energy of the waterfall that passes through the turbine housing 2 is divided between each turbine rotor 55, 56.
The power generation system 54 of this configuration can be installed at the small end of a pipe 57, which provides a high drop of water. THE
Petition 870160013391, of 11/04/2016, p. 29/92
21/23 potential energy from the high water fall is divided between the turbine rotors 55, 56 without the need to separate the different power generation systems that must be positioned spaced along the pipe 57. This configuration is beneficial because all the rotors turbines of the electricity generation system are positioned in a location that is relatively lower in altitude compared to other parts of the pipeline 57, as shown in figure 16. The low altitude location is possibly warmer than a more high and therefore there are chances of being less affected by cold weather and ice, especially in cold and snow-prone regions. In addition, the electrical generators and the corresponding remaining systems are all positioned in a location that is easy to access, rather than positions spaced at an incline along the pipe 57. The electricity generation system is more reliable and easier to perform maintenance than other power generation systems that require turbine generators to be installed at different locations along the pipeline.
The construction of the composite material allows the turbine to operate without obstructions, even if covered by snow, as long as the water passes through the pipeline. It is not necessary to use any type of heating as in the case of a conventional hydroelectric generator.
In this rotor-filled configuration, only one bypass pipe 58 is needed to divert water flow around the single power generation system 54. This single bypass pipe 58 and the reduced number of shut-off valves are easier to implement and operate than other configurations that require multiple bypass lines and shut-off valves.
It should be noted that in other configurations of the invention, an electric power generation system may incorporate more than two turbine rotors and generators of the type described above.
In a preferred embodiment of the invention, the entire power generation system is made of a composite material or a combination of metallic and composite parts. The compounds in the configurations of the invention are,
Petition 870160013391, of 11/04/2016, p. 30/92
22/23 preferably, glass fiber reinforced polymers or carbon fiber reinforced polymers. These types of compounds are relatively inexpensive to manufacture and last longer.
When used in this specification and in the claims, the terms include, own, present, are composed of and variations mean that the specified features, steps or parts are included. The terms should not be interpreted in a way that excludes the presence of other resources, steps or components.
ADVANTAGES OF THE PRESENT INVENTION:
A hydroelectric and pipeline turbine generation system, as described here, has several advantages, including, among other things:
• The system can be installed easily on existing piping using flange ends on the system that attach to the piping. This eliminates the need for a separate man-made dam, spillway or water source. There is also a significant reduction in the land required for hydroelectric power generation; zero / low environmental impact, since there are no floods or deforestation; zero / low environmental social impact, since it is not necessary to relocate or rehabilitate the area's residents; and reduced carbon emissions due to decreased construction requirements.
• the system is simple, compact and modular and provides good energy efficiency;
• the system can be adapted to different hydraulic conditions and heights of falls; and • it is easy to maintain the system and no specialized device is required; the entry guide vane and permanent exit vane can be easily removed from the liner. In the horizontally split liner, the top liner can be removed and then the entry guide vane and permanent exit vane can be removed, repaired or replaced.
Petition 870160013391, of 11/04/2016, p. 31/92
23/23 the system contains only one moving part and the shaft is fixed, making it easy to manufacture, assemble, install and maintain.
the system does not need a separate power plant, which ends up reducing the need for civil construction and the availability of land, causing the least possible environmental impact. The set of a configuration of the invention is more easily approved by the government or local authority since the system does not have a negative impact on the environment.
