    [0001] The invention relates to a method for evaluating the driving parameters of a solar tracker. A solar power plant consists of a series of solar trackers, each solar tracker of the series being composed of a set of solar modules. Each solar module 10 comprises means for treating solar radiation. During the preliminary study of the installation of the solar power plant, the implantation of the different solar modules, and consequently of the different solar trackers, forming the solar power station is realized in order to minimize the slopes between the different solar modules so to get as close as possible to an ideal theoretical layout. A site book is thus pre-established. It should be noted that the slopes between the different solar modules, whatever the direction, can increase the risks of shading between two adjacent solar modules and therefore the phases of correction of tracking the diurnal run of the Sun during the day. This has the direct consequence of reducing the production of the solar power plant, and thus reducing the energy performance of the plant. Currently, in order to optimize the energy performance of the plant by seeking to minimize the losses due to disparities in the installation area of all the solar modules comprising the solar power plant, a set of global control parameters is predefined for the set 30 of the solar power station. However, such a set of global control parameters does not allow optimized control of the solar power plant because such a global parameter set applied to all the solar modules of the solar power plant only takes into account relative positioning. two adjacent solar modules producing the worst risk of shading. Such control of the solar power plant does not optimize the energy performance of the solar power plant. An object of the invention is to provide a method for evaluating control parameters that makes it possible to further optimize the energy performance of a solar power plant by minimizing the losses due to the disparities in the installation area of the different solar modules of the power plant. solar power station.
    [0002] For this purpose, it is provided, according to the invention, a method of evaluating the driving parameters of a series of solar trackers of a solar power plant, each solar tracker of the series of solar trackers comprising a set of solar modules. each solar module comprising a solar radiation processing means table rotatably mounted about an axis of rotation, continuing a diurnal run of the Sun, on ground connection means, the method comprising steps of: a - for each of the ground connection means, note the coordinates in the space of a point of connection with the table; b - for each of the solar modules: i. Determining an inclination of the associated table from the surveyed space coordinates of the ground link means of the associated table; ii. Determining the coordinates of a series of reference points of the associated table from the coordinates in the space of the ground link means of the associated table and the inclination of the associated table; c - determination, for each of the solar modules, of a set of relative positioning parameters of the table associated with direct neighboring tables of the associated table of the solar power station, from the coordinates in the space of the series of points of reference of the considered tables; d - determination, for each of the solar trackers of the series of solar trackers, of the control parameters of the solar tracker considered from the inclination and all the relative positioning parameters of the tables of all the solar modules of the solar tracker considered. Thus, the reading, for each of the ground connection means, of the coordinates in the space of a point of connection with the table makes it possible to determine the actual positioning of the various tables of the solar power station and to calculate own control parameters. to each of the solar trackers that form the solar power plant. As a result, each solar follower in the solar tracker series is independently controlled, which maximizes the energy efficiency of the solar power plant by minimizing the energy losses of the shading risks due to the disparities in the terrain. Advantageously, but optionally, the method according to the invention has at least one of the following additional technical characteristics: the inclination is evaluated with respect to a horizontal; the series of reference points comprises a point of a northern edge of the table, a central point of the table and a point of a southern edge of the table; - the three points are aligned along a North-South axis; 10 - in step C, the direct neighbor tables considered are those that present a risk of shading on the associated table during the diurnal run of the Sun; the set of relative positioning parameters comprises height difference values between the North and South edges of the associated table and the edges opposite the direct neighboring tables; The control parameters of the solar follower considered comprise maximum values of the distributed difference of height values by relative positioning of the associated table and of the direct neighbor table considered; the control parameters of the solar follower considered comprise minimum values of the distance values distributed by relative positioning of the associated table of the direct neighboring table considered; and the driving parameters of the solar follower considered comprise an average value of the inclinations of the tables of all the solar modules of the solar follower considered.
    [0003] Other characteristics and advantages of the invention will appear in the following description of an embodiment of the method according to the invention. In the accompanying drawings - Figure 1 is a schematic top view of an implantation of a solar power plant; FIG. 2 is a schematic view illustrating the determination of the inclination in the method according to the invention; FIGS. 3A and 3B and 4 are diagrammatic views illustrating the determination of a series of reference points according to the method according to the invention; FIGS. 5 to 13 are diagrammatic views illustrating the determination of a set of relative positioning parameters according to the method according to the invention; FIG. 14 illustrates 1 example of tables obtained by the method according to the invention; and, FIG. 15 is a flowchart illustrating the solar plant implantation process, the process comprising the method according to the invention. With reference to the various FIGS. 1 to 15, we will describe a method for evaluating the driving parameters according to the invention. This description is made by considering a solar power plant comprising a set of solar modules called "an axis" each comprising a table formed by means of solar radiation treatment. Each of the tables is rotatably mounted along a substantially horizontal axis on a set of three piles 30 substantially aligned in a north-south direction. Such modules are described in more detail in document FR 12 55 956, to which reference can be made for further information. However, the control method according to the invention which will be described can be applied to other types of solar modules forming a solar power station. In particular, the evaluation method of the driving parameters according to the invention can be applied to so-called "two-axis" solar modules, as well as to solar trackers comprising from one to several solar modules driven by the same control unit. piloting. In FIG. 1, a solar power station 10 here comprises three solar trackers 20, 30, 40. Each of the solar trackers 20, 30, 40 comprises a set of solar modules 50, here four in number. Each of the solar modules 50 comprises a table 1, 2, 3, 4, 5, 6, 7, 8, A formed of means for treating solar radiation. These tables are rectangular in shape and oriented in a North-South direction. Each of the tables is mounted to rotate about an axis of rotation on ground connection means P1, P2, P3, which are here beaten up in a soil S on which the solar power plant 10 is implanted. Such ground connection means are illustrated for example in FIG. 2. With reference to FIG. 15, the installation of the solar power station 10 is first theoretically performed during a study 103, which allows 104. This layout sheet 104 is implemented on the site of installation of the solar power station 10 during a construction site 105 during which all the ground connection means P1, P2, P3 are implanted in the soil S on which the solar power station 50 is installed.
    [0004] It should be noted that the disparities of the soil S illustrated in Figures 2, 3a, 3b and 7 to 12 are voluntarily amplified for a purely illustrative purpose of the following. Once the worksite 105 is completed or as it progresses, a first step 110 of the evaluation method of the control parameters 100 according to the invention is performed. This step 110 consists in recording, for each of the ground connection means P1, P2, P3, coordinates in the space of a point of connection with the table which is then mounted to rotate about an axis on this connecting means. In the case of solar modules "an axis" illustrated here, it is the vertices of a free end of the piles Pl, P2, P3. These coordinates in space are an orthonormal landmark (0, X, Y, Z). In general, this reference is, by calculation if necessary, a reference centered south-west of the solar power station 10, whose Y axis is in the direction of the length of the tables 1,2,3,4,5, 6,7,8, A and the Z axis is collinear with a normal of the natural terrain represented by the soil S. The type of calculation performed depends on the report of the surveyor and his assumptions concerning the site of implantation of the plant 10. The set of these coordinates in the space of a point of connection with the table forms a workbook 120. From this workbook 120, the method of evaluating the driving parameters 100 according to the the invention determines, in a global step 130, a set of control parameters 140 associated with each of the solar trackers 20, 30, 40 forming the solar power station 50.
    [0005] Referring to Figures 2 to 13, we will now describe in detail the various control parameters 140 determined by the evaluation method of the control parameters 100 according to the invention. In a first step, the evaluation method of the control parameters according to the invention comprises a preliminary calculation step. This step makes it possible to characterize each table 1,2,3,4,5,6,7,8, which is part of the solar power station 10 and therefore different solar trackers 20,30,40. Each table A is then located completely in space. Thanks to the coordinates (X, Y, Z) in the space of the points of connection with the table A of the piles P1, P2, P3 in the proofing register, a simple calculation makes it possible to locate the North and South edges of the tables, as well as as their inclination. This calculation depends on the dimensions of the tables that are previously known.
    [0006] In the box illustrating the method for evaluating the driving parameters 100 according to the invention, the inclination of the table A is defined as being the angle a between a straight line passing through the vertex forming a point of connection with the table A extreme piles P1, P3, and a horizontal passing through these same piles as is illustrated in FIG. 2. The respective vertices of the piles P1 and P3 have for their respective spatial coordinates (X1, Y1, Z1) and (X3, Y3 , Z3). The inclination a of each table A is then determined using the altitude Z1, Z3 of the vertices of the piles P1, P3 and a distance Y1-Y3 between these two end piles P1, P3. The inclination a is considered positive when the table A is oriented towards the south as in FIG. 2; only the extreme piles (P1 and P3) are taken into account in the calculation. The equation is:, a = Atan (Zi-Z3) (1)) (1 -) (3 The inclination a being known, reference points M1, M2, M3 for each of the tables A are calculated, knowing a North overflow DN and a south overflow Ds of the table A. Thus, the point M1 is located on a northern edge of the table A considered and the point M3 is located on a southern edge of the table A considered, while the point M2 corresponds at the point of connection with the table A considered of the connecting means P2, that is to say the top of the free end of the pile P2 here, Figures 3a and 3b illustrate this situation. in the space of the points of connection with the table A ground connection means P1, P2, P3 to the coordinates in the space of the reference points M1, M2, M3 associated with the table A considered, illustrated in FIG. 4, are: Xmi = Xm2 = Xm3 = X2 (2) Yiva = Y1 + cos (a) DN (3) YM2 - Y2 (4) Ym3 = Y3 - cos (a) Ds (5) ZM1 = Z1 + sin ( a) DN (6) Zm2 = Z2 (7) Zm3 = Z3 - sin (a) Ds (8) The reference points M1, M2, M3 are therefore aligned along a North-South axis.
    [0007] When mounting a table A, the middle pile P2 serves as a reference for North / South positioning. In practice, the misalignment of the piles P1, P2, P3 are corrected by supports axis of the P1 and P3 piles, as described in the document FR 12 55956. Therefore, the abscissa X of the reference points M1, M2, M3 is considered identical and equal to that of the pile P2 (Equation 2). At the end of this preliminary calculation step, at each table A of the set of solar modules 50 forming the solar power station 10 is associated a series of reference points Ml, M2, M3 (here three in number). It is now necessary to locate the tables A between them, that is to say, to record for each table A the coordinates of the reference points of the neighboring tables 1,2,3,4,5,6,7,8. From here, the evaluation method of the control parameters 100 according to the invention will determine, for each table A of the set of solar modules 50, a set of relative positioning parameters of the table A considered in relation to the tables. direct neighbors 1,2,3,4,5,6,7,8 of said table A considered. These relative positioning parameters are summarized in the following table: Parameters Tables considered AzL-OE A-5 AzL-E0 A-4 AzOEDS A-3 AzEODS A-1 AzOEDN A-8 AzEODN A-6 DEW A-5 DNSN 2 The first six relative positioning parameters of the table correspond to differences in heights Az between the table A considered and the direct neighboring tables 1,3,4,5,6 and 8 respectively situated in the North. West, Northeast, East, West, Southwest and Southeast. The last three relative positioning parameters of the table correspond to distances between the table A considered and the neighboring direct tables 2.5 and 7, situated respectively in the North, in the East and in the South.
    [0008] On the other hand, the implementation guide 104 allows to know three theoretical relative positioning parameters that are: - Dewih: Theoretical distance between a table and its neighbor in the East or the West - Dnsnth: Theoretical distance between a table and its neighbor to the North - Dnssth: Theoretical distance between a table and its neighbor in the South It should be noted that these theoretical relative positioning parameters correspond to the last three positioning parameters of the preceding table. With reference to FIGS. 5 to 13, we will describe the calculation for each table A of the set of relative relative positioning parameters, according to the evaluation method of the control parameters 100 according to the invention.
    [0009] The parameter AzL-0E (Figure 5) reflects a difference in height between two tables located West-East on the same line; it is taken into account in a control strategy of the solar power station 10 when the sun is in the west and that table A may cause shading on the table 5 in the east. The calculation of this AzL-OE parameter is based on the heights at the edge of the table. For each of the three reference points M1, M2, M3 of the table A, the reference points M51, M52, M53 of the table 5 in the East are searched for and then subtract their height. The procedure and the assumptions of the calculation, carried out for each reference point of all the tables of the solar power station, are as follows: the search for the reference point of the table 5 located in the East is based on the comparison the abscissa and the ordinate of the points. Let i denote the reference point number M5i, i E {1,2,3}; 10 to take into account the threshing tolerances of the piles P1, P2, P3 and the calculation uncertainties, a circle of radius 50 cm inside which the pile is located is defined; the coordinates (XN5j, YN5j) of the reference point of the table 5 located in the east must check: IXms - Xmi - Dewthl <0.5 IYms, Ymil <0.5 Once the reference point has been identified M5i, the Az corresponding to the same reference point Mi of the table A 20 considered is calculated. This result is given in the following table: Point table of AzL-OE reference A M1 ZM1 -4451 A2 A ZM2 - ZM52 A M3 ZM3 - ZM53 The evaluation method of the control parameters 100 according to the invention then retains only the maximum value among these three values.
    [0010] The process proceeds to the next iteration, that is to say to the next table, thus scanning all the tables of all the solar modules 50 of the solar power station 10. For the tables located at the end of the line at East, no value is given, since these tables have no direct neighbors to the East. Concerning now the parameter AzL-E0 (FIG. 6), the latter translates a difference in height between two tables implanted East-West on the same line; it is taken into account in the control strategy of the solar power station 10 when the Sun is in the East and that the table A may cause shading on the table 4 in the West. The calculation of this parameter AzL-E0 is, as for the previous one, according to the heights at the edge of the table. For each of the three reference points M1, M2, M3 of the table A, the reference points M41, M42, M43 of the table 4 in the West are searched for and then subtract their height.
    [0011] Similarly, for the previous AzL-OE parameter, the procedure and the assumptions of the calculation, carried out for each reference point of all the tables of the solar power station, are as follows: the search of the reference point of the table 4 located in the West is based on the comparison of the abscissa and the ordinate of the points. Let i denote the reference point number M4i, i E {1,2,3}; - to take into account the threshing tolerances of the P1, P2, P3 piles and the calculation uncertainties, a circle of radius 50 cm inside which the pile is located is defined; the coordinates (XN4i, YN4i) of the reference point of Table 4 located in the East must verify: IXm4i - Xmi - Dewth I <0.5 IYm4i Ymi I <0.5 Once the reference point has been identified M4i, the Az corresponding to the same reference point Mi of the table A considered is calculated. This result is given in the following table: Table Point of AzL-E0 reference A M1 ZM1 - 4441 A M2 ZM2 - 4442 A M3 ZM3 - ZM43 Again, the evaluation method of the control parameters 100 according to the invention while the maximum value among these three values. The process proceeds to the next iteration, that is to say to the next table, thus scanning all the tables of all the solar modules 50 of the solar power station 10. For the tables located at the end of the line at in the West, no value is given, since these tables have no direct neighbors 4 in the West.
    [0012] For the AzOEDS parameter (Figure 7), the latter translates a difference in height between two tables located diagonally north-east; it is taken into account in the management strategy of the solar power station 10 when the Sun is in the South-West and that the table A risks shading on the table 3 in the North-East. The calculation of this parameter AzL-E0 is, as for the previous ones, according to the heights at the edge of the table. For reference point M1 of table A, the reference point M33 of table 3 in the north-east is searched for and then subtract their height. Indeed, in this situation, the northern edge of Table A extended to the East is facing the South edge of Table 3 in the Northeast. Similarly, for the preceding parameters, the flow and the assumptions of the calculation, carried out for the reference point M1 of all the tables of the solar power station, are the following: the search of the reference point of the table 3 located in the Northeast is based on the comparison of the abscissa and the ordinate of the points; In order to take into account the pile threshing tolerances P1, P2, P3 and the calculation uncertainties, a circle of radius 50 cm inside which the pile is located is defined; the coordinates (X1, 133, Y1, 133) of the reference point of the table 3 situated to the North-East must verify: IXm33-Xmi-Dewth I <0.5 IYM33-YM1-Dnsnth I <0.5 Once the identified reference point M33, the Az relative to the reference point Ml of the considered table A is calculated: AzOEDS = Zmi - 4433. The process proceeds to the next iteration, ie to the next table, thus scanning all the tables of all the solar modules 50 of the solar power station 10. For the tables A not having from neighbor 3 to the Northeast and / or for the reference points M2 and M3, no value is indicated.
    [0013] Concerning now the parameter AzEODS (figure 8), it translates a difference of height between two tables located diagonally North-West; it is taken into account in the control strategy of the solar power station 10 when the Sun is in the South-East and that the table A risks shading on the table 1 in the North-West. Again, the calculation of this AzEODS parameter is based on the heights at the edge of the table. For the reference point M1 of each table A, the reference point M13 of the table 1 in the North-West is searched for and then subtract their heights. Indeed, in this situation, the northern edge of table A extended to the west is facing the south edge of table 1 in the northwest. As for the previous parameter, the flow and the assumptions of the computation, carried out for the reference point M1 20 of all the tables of the solar power station, are the following: the search of the reference point of the table 1 located in the North -West is based on the comparison of the abscissa and the ordinate of the points; - to take into account the threshing tolerances of the P1, P2, P3 piles and the calculation uncertainties, a circle of radius 50 cm inside which the pile is located is defined; the coordinates (X1, 113, Y1, 111) of the reference point of the north-west table 1 should verify: IXm3-Xmi-Dewth I <0.5 IYM13 -Yi "- Dnsnth I <0.5 once the identified reference point M13, the Az with respect to the reference point M1 of the considered table A is calculated: AzEODS = Zmi - 4413.
    [0014] The process proceeds to the next iteration, ie to the next table, thus scanning all the tables of all the solar modules 50 of the solar power station 10. For the tables A having no neighbor 1 in the North-West and / or for the reference points M2 and M3, no value is indicated. We will, with reference to FIG. 9, now evaluate the parameter AzOEDN which translates a difference in height between two tables implanted diagonally Southeast; it is taken into account in the control strategy of the solar power station 10 when the Sun is in the North-West and that table A is likely to cause shading on the table 8 in the South-East. Again, the calculation of this AzOEDN parameter is based on the heights at the edge of the table. For reference point M3 of each table A, the reference point M81 of table 8 in the Southeast is searched for and then subtract their heights. Indeed, in this situation, the southern edge of table A extended to the east is facing the north edge of table 8 in the southeast. As before, the procedure and the assumptions of the calculation, carried out for the reference point M1 of the set of tables of the solar power station, are as follows: the search of the reference point of the table 8 located in the southeast is based on the comparison of the abscissa and the ordinate of the points; - to take into account the threshing tolerances of the P1, P2, P3 piles and the calculation uncertainties, a circle of radius 50 cm inside which the pile is located is defined; the coordinates (XKII, YKII) of the reference point of Table 8 located to the South-East should check: 1.481-Xm3 - Dewthl <0.5 IYmBi - "M3 - Dnssth I <0.5 Once the reference point has been identified M81, the Az relative to the reference point M3 of the considered table A is calculated: AzOEDN = Zm3-4481 The process proceeds to the next iteration, i.e. to the next table, thus sweeping the all the tables of 15 all the solar modules 50 of the solar power station 10. For the tables A having no neighbor 8 in the Southeast and / or for the reference points M1 and M2, no value is filled 20 Now, with reference to Figure 10, we will evaluate the parameter AzEODN, which translates a difference in height between two diagonally southwestern tables, which is taken into account in the control strategy of the solar power plant. when the Sun is in the North-East and Table A may cause shading on the Table 6 in the Southwest Again, the calculation of this parameter AzEODN is based on the heights at the edge of the table. For reference point M3 of each table A, reference point M61 of table 6 in the Southwest is searched for then subtracting their heights. Indeed, in this situation, the southern edge of table A extended to the west is facing the north edge of table 6 in the southwest. As before, the procedure and the assumptions of the calculation, performed for the reference point M1 of all the tables of the solar power station, are as follows: the search for the reference point of the table 6 situated in the South-West is based on the comparison of the abscissa and the ordinate of the points; 10 to take into account the threshing tolerances of the piles P1, P2, P3 and the calculation uncertainties, a circle of radius 50 cm inside which the pile is located is defined; the coordinates (X1, 161, YN61) of the reference point of the south-west table 6 must verify: Xm61 - XM3 - Dewth I <0.5 IYm61 - "M3 - Dnssth I <0.5 Once the identified reference point M61, the Az relative to the reference point M3 of the table A considered is calculated: AzEODN = ZM3 - 4461 The process proceeds to the next iteration, ie to the next table , thus sweeping all the tables of all the solar modules 50 of the solar power station 10. 25 For the tables A having no neighbor 6 in the Southwest and / or for the reference points M1 and M2, no This value is not filled in. It should be noted that the theoretical values of the distances Dnsnth, Dnssth and Dewth, resulting from the study 103, were used for the previous calculations, associated with a tolerance of 0.5 m, reference were found on all the tables A of the solar plant 10 and the differences in height Az could be e calculated for all the tables A of the solar power station 10. It is now necessary to refine these distance values Dnsn, Dnss and Dew. Again, the values for each of the tables A of the solar plant 10 will be calculated.
    [0015] With reference to FIG. 11, the distance East / West, DEW, corresponds to a difference of the abscissae of the reference points M2 of two neighboring tables, here Table A and its direct neighbor to the East, located on the same East-West line. As seen previously, it is the piles P2 that determine the North / South alignment of the tables A. Again, the calculation is performed on all the tables A of the solar power station 10. The parameter DEW is given by the equation: DEW = Xms, - Xm, It is possible to consider, as a variant, the table A and its neighbor 20 to the west, the table 4, to calculate the parameter DEW. With reference to FIG. 12, the DNSN distance corresponds to the difference of the ordinates of the M3 reference points of two neighboring tables, aligned in the North / South direction. It is first necessary to locate the table 2 located north of the table A considered, then subtract the ordinates of the points M3. Again this calculation is performed on all the tables A of the solar plant 10. The DNSN parameter is given by the equation: DNSN = Ym23 - Ym,.
    [0016] Finally, with reference to FIG. 13, the distance DNSS corresponds to the difference of the ordinates of the reference points M1 of two neighboring tables, aligned in the North / South direction. It is first necessary to locate the table 7 located south of the table A considered, then subtract the ordinates of the points Ml. Again, this calculation is performed on all the tables A of the solar power station 10.The DNSS parameter is given by the equation: DNSS =) (M1-Yrw71.
    [0017] The set of relative positioning parameters AzL-0E, AzL-E0, AzOEDS, AzEODS, AzOEDN, AzEODN, DEW, DNSN and DNSS is calculated for each of the tables A of all the solar modules 50 of the solar tracker series. 20,30,40 from the solar power station 10. Once this step has been performed, the method for evaluating the driving parameters 100 according to the invention will, for each of the solar trackers 20,30,40 of the solar power station 10, determine a set of control parameters specific to the solar tracker 20,30,40 considered from the inclinations and sets of relative positioning parameters of the tables A of the set of solar modules 50 forming the solar follower 20,30,40 considered. In the case illustrated in the figures, for each solar follower 20,30,40 of the solar power station 10, the evaluation method of the control parameters 100 according to the invention calculates an average Amoy inclination from the inclinations to the tables A of all the solar modules 50 forming the solar follower 20,30,40 considered. Then, the evaluation method of the control parameters 100 according to the invention determines a first subset of control parameters AZL-0Emax, OZL-EAmax, AzOEDSmaxr AzEODSmaxr AzOEDNrnax and AzEODNmax corresponding to the maximum values of the relative positioning parameters respectively AzL -0E, AzL-E0, AzOEDS, AzEODS, AzOEDN and AzEODN of the set of solar modules 50 forming the solar follower 20,30,40 considered. Next, the evaluation method of the control parameters 100 according to the invention determines a second subset of control parameters DEWrnin, DNSNrnir, and DNSSmin corresponding to the minimum of the positioning parameters respectively DEW, DNSN and DNSS of the set of solar 50 forming the solar follower 20,30,40 considered.
    [0018] The table of FIG. 14 illustrates an example of a practical result resulting from the evaluation method of the control parameters 100 according to the invention. The various solar trackers 20,30,40 of the solar power station 10 are labeled "Zi Rj Tk" in this table. For the solar tracker "Z1 R2 T2", the latter comprises a set of twenty-seven solar modules 50, numbered from 1 to 27 in the table. The set of relative positioning parameters of the twenty-seven tables of the solar modules 50 has been reported in the table.
    [0019] The evaluation method of the driving parameters 100 according to the invention makes it possible to customize a set of driving parameters for each solar follower 20, 30, 40 forming the solar power station 10. Thus, the control system of the solar power station 10 adapts the piloting the solar tracker or only those involved in shading a table of one of their solar modules 50 on one of the direct neighboring tables. This maximizes the energy production of the solar power station 10 during the daytime run of the sun. However, it is possible to make numerous modifications to the invention without departing from the scope thereof.
