METHOD AND DEVICE FOR CONTROLLING A TURBINE, COMPUTER PROGRAM

Description

[0001] The invention relates to a method and device for adjusting a double-adjusted reaction turbine, as well as to a computer program for their implementation.

[0002] The field of the invention relates in particular to electricity production turbines.

[0003] Such reaction turbines are known with double adjustment, namely with adjustment of the orientation of the blades and with adjustment of the orientation of the guide vanes; said guide vanes are also called sluice gates.

[0004] The set of measurements used to find and / or optimize the conjugation laws of these two settings is called Index Test, standardized by the international standard IEC60041.

[0005] Document RU2743704C1 describes a method of adjusting a turbine according to the preamble of claim 1.

[0006] We also know adjustment methods, requiring a measurement of the turbine fluid flow rate to find the optimal operating point on these two settings.

[0007] The flow rate defines the kinematics of the fluid in the turbine body. It is therefore a priori a key quantity for a search for the best combination of valve and blade settings.

[0008] However, measuring the fluid flow rate can be difficult to obtain, for example due to the accessibility to the measurement sections (fluid flow section or areas where the measurement sensor installation points are located), the available distance from straight sections on the hydraulic circuit, etc. In addition, the installation of flow measurement means can be risky in terms of personal safety depending on the accessibility of the measurement sections.

[0009] Measuring fluid flow can also be expensive in terms of equipment: depending on the design of the facilities, a trolley may be necessary to implement the sensors, which must be multiplied in number depending on the flow section. In some cases, the condition of the pressure taps also has a significant impact on the reliability and consistency of the results obtained.

[0010] Such a fluid flow measurement installation requires human resources and remains unreliable. Indeed, depending on the layout, the geometry of the measurement sections is not always verifiable (impossibility of taking geometric readings, combined with old or even incomplete plans) or includes geometric singularities requiring measurement corrections, the distance between the turbine and the measurement section may be insufficient and does not allow the fluid to have an ideally laminar behavior avoiding hydraulic turbulence harmful to the measurement. The reliability of the measurements also depends on measurement uncertainties and metrological monitoring of the sensors involved in the measurement.

[0011] The present invention aims to obtain a method and a device for adjusting the turbine, as well as a computer program for their implementation, which improve the current situation by proposing a control law which combines the adjustment of the blades and the adjustment of the valve, while avoiding the measurement of the fluid flow rate.

[0012] To this end, a first object of the invention is a method of adjusting a turbine, the turbine having a rotation shaft and blades, which are fixed on the rotation shaft and of which a first orientation relative to a transverse plane, perpendicular to the rotation shaft, is adjustable according to a first blade orientation command, the turbine having a fluid inlet path and fluid valve guide vanes, which are located between the fluid inlet path and the blades and of which a second valve orientation is adjustable according to a second fluid valve guide vane orientation command, method in which, during a first step, first sets of combinations, called sets of first iso-power points, of first values ​​of the first blade orientation command and of first values ​​of the second fluid valve guide vane orientation command, are determined by a control module for a plurality of target electrical powers of the turbine,each set of first iso-power points corresponding to one of the target electrical powers of the turbine, characterized in that during a second step, the control module determines for each target electrical power in each set of first iso-power points the first iso-power point having a maximum slope break in absolute value, called the optimum adjustment point for each target electrical power, during a third step, the control module records the optimum adjustment points for the plurality of target electrical powers of the turbine.

[0013] According to one embodiment of the invention, during the first step, during a first sub-step, a first initial conjugation law is entered into the control module, giving the first blade orientation command as a function of the second fluid control guide vane orientation command, the initial conjugation law corresponding to an initial programming of a turbine control automaton for at least one given head height of the turbine, during a second sub-step, the control module calculates a grid of second points located in a prescribed envelope around the initial conjugation law, the second points having coordinates Y p,j and Y v,i for i ranging from 1 to N and for j ranging from 1 to M, where Y p,j is the first blade orientation command, Y v,i is the second fluid control guide vane orientation command, N is a first prescribed natural integer, greater than or equal to 2, M is a second prescribed natural integer,greater than or equal to 2, with , Y v , i + 1 = Y v , i + δ , And Y p , i + 1 = Y p , i + δ ′ , δ being a prescribed step of second command of orientation of the fluid valve guide vanes and being non-zero, δ' being a prescribed step of first command of orientation of the blades and being non-zero, during a third sub-step, the control module obtains the flow rate of the turbine for each second point from a second prescribed law, giving the value of the flow rate Q(Y p,j , Y v,i ) of the turbine as a function of Y p,j and Y v,i , during a fourth sub-step, the control module selects, for each second point having the coordinates Y p,j and Y v,i for i ranging from 1 to N and for j ranging from 1 to M, a third point having coordinates Y' p,j and Y' v,i which correspond to those of the coordinates Y p,j and Y v,i which minimize Q Y vi + 1 Y pj − Q Y vi , Y pj ; Q Y vi + 1 Y pj + 1 − Q Y vi , Y pj ; Q Y vi Y pj + 1 − Q Y vi , Y pj ; Q Y vi Y pj − 1 − Q Y vi , Y pj ; Q Y vi + 1 Y pj − 1 − Q Y vi , Y pj ; Q Y vi − 1 Y pj + 1 − Q Y vi , Y pj ; Q Y vi − 1 Y pj − Q Y vi , Y pj ; Q Y vi − 1 Y pj − 1 − Q Y vi , Y pj ; , where Y' p,j is the first blade orientation command, Y' v,i is the second fluid control vane orientation command, during a fifth sub-step, the control module on the turbine, for each at least one given drop height, sets the second fluid control vane orientation command Y' v,i, associated with the first blade orientation command Y' p,j according to each third point, then an electrical power P corresponding to each third point is measured by a power measuring device provided on the turbine and quadruplets (Y' p,j , Y' v,i , H, P) of data giving in association the first blade orientation command Y' p,j, the second fluid control vane orientation command Y' v,i,the at least one given drop height and the electrical power P having been measured and corresponding to each third point, during a sixth sub-step, the control module determines from the quadruplets (Y' p,j , Y' v,i , H, P) of data the target electrical powers and the first iso-power points associated with the target electrical powers.

[0014] According to one embodiment of the invention, the target electrical powers are equal to the electrical powers P having been measured and corresponding to the third points.

[0015] According to an embodiment of the invention, during the first step, the control module calculates during the sixth sub-step the target electrical powers and the first iso-power points by interpolation from the quadruplets (Y' p,j , Y' v,i , H, P) of data.

[0016] According to one embodiment of the invention, the envelope prescribed around the starting conjugation law is formed by a zone between a lower envelope curve and an upper envelope curve, which are located respectively below and above the starting conjugation law according to the first blade orientation command.

[0017] According to one embodiment of the invention, the lower envelope curve corresponds to the starting conjugation law, having been shifted by a first prescribed shift downwards according to the first blade orientation command, and the upper envelope curve corresponds to the starting conjugation law, having been shifted by a second prescribed shift upwards according to the first blade orientation command.

[0018] According to an embodiment of the invention, during the third sub-step, the control module obtains the second law from previously recorded turbine flow rate measurements for certain values ​​of the first blade orientation command and / or the second fluid control guide vane orientation command Y' v,i, or from a flow rate model for certain values ​​of the first blade orientation command and / or the second fluid control guide vane orientation command Y' v,i.

[0019] According to another embodiment of the invention, during the first step, during another first sub-step, for each of the target electrical powers, the control module on the turbine sets the first blade orientation command successively to a first selected adjustment value from among several first prescribed adjustment values ​​of the first blade orientation command for at least one given drop height of the turbine, an electrical power of the turbine is measured by a power measuring member provided on the turbine, and the control module on the turbine sets, for each first selected adjustment value of the first blade orientation command and for each at least one given drop height of the turbine,the second fluid throttling guide vane orientation command successively at a second selected setting value from among several second prescribed setting values ​​of the second fluid throttling guide vane orientation command, until the electrical power measured on the turbine is equal to the target electrical power, during another second sub-step, data quadruplets giving each first selected setting value of the first blade orientation command in association with the at least one given head height of the turbine, with the target electrical power and with the second selected setting value of the second fluid throttling guide vane orientation command, for which the electrical power measured on the turbine is equal to the target electrical power,during another third sub-step, the control module determines from the data quadruplets the target electrical powers and the first iso-power points associated with the target electrical powers.

[0020] A second object of the invention is a device for adjusting a turbine, the turbine having a rotation shaft and blades, which are fixed on the rotation shaft and of which a first orientation relative to a transverse plane, perpendicular to the rotation shaft, is adjustable according to a first blade orientation command, the turbine having a fluid inlet path and fluid valve guide vanes, which are located between the fluid inlet path and the blades and of which a second valve orientation is adjustable according to a second fluid valve guide vane orientation command, the device comprising a control module configured to determine for a plurality of target electrical powers of the turbine, first sets of combinations, called sets of first iso-power points, of first values ​​of the first blade orientation command and of first values ​​of the second fluid valve guide vane orientation command,each set of first iso-power points corresponding to one of the target electrical powers of the turbine, characterized in that the control module (MOD) is configured to determine for each target electrical power by the control module in each set of first iso-power points, the first iso-power point having a maximum slope break in absolute value, called optimum adjustment point of each target electrical power, record in a database of the control module the optimum adjustment points for the plurality of target electrical powers of the turbine.

[0023] The method for adjusting the turbine 1 according to the invention and the device 100 for adjusting the turbine 1 according to the invention, implementing this adjustment method, are described below with reference to figures 1 to 12 .

[0024] We first describe below in more detail with reference to the figures 1 to 6 examples of turbine 1. Turbine 1 may be a turbine of a turbo-alternator for generating electricity or a turbine of an electricity generator, or other. As described below, turbine 1 is a reaction turbine with double adjustment Y p , Y v of the blades 12 and guide vanes 14. Turbine 1 is controlled by regulating members 121, 141 of fluid admission 141

[0025] The turbine 1 comprises a rotation shaft 11, which is mounted to rotate in a frame 10 about a first rotation axis 110. Blades 12 are fixed on the rotation shaft 11, around it. The frame 10 comprises a fluid inlet path 101 (for example a spiral tank 101), in which fluid is sent to the blades 12. The frame 10 comprises a fluid outlet path 103, in which the fluid is sent from the blades 12. The blades 12 are located between the fluid inlet path 101 and the fluid outlet path 103. The fluid may be, for example, water, or other, such as, for example, steam, or air for a wind turbine. figure 1 , turbine 1 is for example of the vertical shaft type 11. At the figure 6 , the turbine 1 is for example of the horizontal shaft 11 type.

[0026] Each blade 12 is mounted to rotate around the shaft 11 around a second axis of rotation 122 perpendicular to the first axis 110 of rotation. The second axes of rotation 122 of the blades 12 are spaced apart from each other around the first axis 110 of rotation. For example, the blades 12 are identical to each other. The first orientation ANGP of each blade 12 (for example of the mean plane 120 of each blade 12 or of a reference plane 120 of each blade 12) around its second axis of rotation 122 relative to a transverse plane 13, perpendicular to the first axis 110 of rotation, is adjustable according to a first control Y p of orientation of the blades 12 (or position Y p of the blades 12), as shown in Figures 4 and 5. The first orientation ANGP can be adjusted in common and in the same direction for all the blades 12, and this by one (or more) first adjusting member 121 (or first adjusting actuator 121), for example by a piston 121 provided on the shaft 11 (or by another adjusting member 121). The translation of the piston 121 along the first axis 110 of rotation rotates, by means of an articulation mechanism, the blades 12 each around their second axis of rotation 122, to adjust the first orientation ANGP of the blades 12 around their second axis of rotation 122. The flow 102 of fluid drives the blades 12 and the shaft 11 in rotation around the first axis 110 of rotation. The rotation of the shaft 11 makes it possible, for example, to generate electricity in the case where the shaft 11 of the turbine 1 is connected to an alternator.

[0027] The adjustment of the first ANGP orientation can be quantified in percentage of orientation (or in linear stroke in metric units of the piston 121, allowing the synchronization of the orientation of the blades 12). Thus 0% for the first ANGP orientation corresponds to a configuration of the blades 12 all oriented according to a flattest profile (called first minimum opening) minimizing the passage section between the blades 12, as shown by way of example in figure 4 where ANGP = 0°. Similarly, 100% for the first ANGP orientation corresponds to a configuration of the blades 12 all oriented according to a profile (called first maximum opening) maximizing the passage section between the blades 12, that is to say with the first ANGP orientation equal to a first prescribed maximum orientation.

[0028] The adjustment of the first orientation ANGP or the first angle ANGP of the blades 12 between the average or reference plane 120 of the blade 12 and the normal plane 13 according to the Figures 4 and 5 can also be located between a minimum value and a maximum value.

[0029] Between the fluid inlet path 101 and the blades 12 are provided guide vanes 14 for controlling the fluid. The function of the guide vanes 14 for controlling the fluid is to predetermine a volume of fluid passage between the fluid inlet path 101 and the fluid outlet path 103.

[0030] Each sluice guide vane 14 is mounted to rotate relative to the frame 10 about a third axis 142 of rotation (for example a vortex 142), which may be, for example, parallel to the first axis 110 of rotation. The third axes of rotation 142 of the sluice guide vanes 14 are spaced apart from each other about the first axis 110 of rotation. The convergent type geometry of the inlet path 101 makes it possible to pre-orient the velocity vectors 102 of the fluid entering each passage section between two consecutive sluice guide vanes 14. For example, the sluice guide vanes 14 are identical to each other. Each sluice guide vane 14 is, for example, in the form of a profiled shroud.The second sluicing orientation ANGV (or second angle ANGV) of each sluicing guide vane 14 (for example of the mean plane 140 of each sluicing guide vane 14 or of a reference plane 140 of each sluicing guide vane 14) around its third axis 142 of rotation relative to a radial plane 143 passing through the first axis 110 of rotation, is adjustable according to a second control Y v of orientation of the sluicing guide vanes 14 (or position of the sluicing Y v ), as shown in . figures 2 And 3The second sluicing orientation ANGV can be adjusted in common and in the same direction for all of the sluicing guide vanes 14, and this by one (or more) second regulating member 141 (or second adjustment actuator 141), for example by a sluicing circle 141 connected to the guide vanes 14 or by another adjustment actuator 141. Each sluicing guide vane 14 is connected by means of a lever 148 and a connecting rod 149 to the sluicing circle 141. The valve circle 141 is further connected via one or more control rods 145 which can be translated by one or more servomotors 144 to rotate the valve circle 141 around the first axis 110 of rotation and to rotate the valve guide vanes 14 each around their second axis of rotation 122, to adjust the second valve orientation ANGV of the guide vanes 14 around their third axis 142 of rotation.The set of guide vanes 14 is called a valve or distributor. The second valve orientation ANGV makes it possible to adjust the fluid passage section between two consecutive valve guide vanes 14.

[0031] The adjustment of the second throttling orientation ANGV can be quantified as a percentage of opening of the guide vanes 14 (or as a linear stroke in metric units of the servomotor(s) 144 which maneuver(s) the throttling circle 141). Thus 0% for the second throttling orientation ANGV corresponds to a configuration (called second minimum opening) of the guide vanes 14 all oriented according to a profile minimizing the passage section between the guide vanes 14 and for example not allowing any fluid to pass between the guide vanes 14 in a position 14F of closing of the guide vanes 14 touching each other as shown in broken lines in figure 3. Similarly, 100% for the second sluicing orientation ANGV corresponds to a configuration (called second maximum opening) of the guide vanes 14 all oriented according to a profile maximizing the passage section between the guide vanes 14, that is to say with the second sluicing orientation ANGV equal to a second sluicing orientation ANGV, maximum prescribed in the fully open or maximum position of the guide vanes 14. The arrow 146 of the figures 2 And 3 corresponds to the direction of closing of the sluice gate guide vanes 14 towards the closing position 14 F. The arrow 147 of the figures 2 And 3 corresponds to the direction of opening of the sluice gate vanes 14 from the closed position 14F to the fully open or maximum position of the sluice gate vanes 14.

[0032] The device 100 for adjusting the turbine 1 according to the invention comprises a control module MOD, configured (programmed) to implement the steps described below of the adjustment method according to the invention, with reference to figures 7 to 12 The control module MOD may comprise several computers, and / or one or more processors, and / or one or more microprocessors, and / or one or more computers, and / or one or more computer programs, and / or one or more INT1, INT2 data input interfaces, and / or one or more INT3 data output interfaces, or others.

[0033] The MOD module is based on an iso-power method for determining the laws of conjugation of the blades 12 and sluicing of the guide vanes 14 of the double-adjustment reaction turbines 1.

[0034] During a first step E1, the control module MOD determines for a plurality of target electrical powers P 1 , P 2 , P 3 , P 4 , P 5 , ... P n of the turbine 1, respectively first sets Y1, Y2, Y3, Y4, Y5,... Yn of combinations Y p , Y v of first values ​​of the first command Y p for orientation of the blades 12 and first values ​​of the second command Y v for orientation of the fluid control guide vanes 14, as shown by way of example in figure 8. Each target power P 1 , P 2 , ... P n can be prescribed in the control module MOD. Each target power P 1 , P 2 , ... P n corresponds to an electrical power value, which can be produced by the turbine 1. These first sets Y1, Y2, ... Yn of combinations Y p , Y v of first values ​​of the first command Y p for orientation of the blades 12 and of first values ​​of the second command Y v for orientation of the fluid control guide vanes 14 are called sets or curves Y1, Y2, ... Yn of first points Y p , Y v of iso-power. Each set Y1, Y2, ... Yn of first points Y p , Y v of iso-power corresponds to one of the target electrical powers P 1 , P 2 , ... P n of the turbine 1. The target electrical powers P 1 , P 2 , ... P n can be prescribed. Each set or curve Y1, Y2, ...Yn of first points Y p , Y v of iso-power gives a first value of the first command Y p of orientation of the blades 12, which is decreasing according to the first value of the second command Y v of orientation of the guide vanes 14 of fluid throttling.

[0035] An example of a curve Y1 of first points Y p , Y v of iso-power for the target electric power P 1 is represented in figure 11 This curve Y1 passes through the first iso-power points {Y v1 , Y p1}, {Y v2 , Y p2}, {Y v3 , Y p3}, {Y v4 , Y p4} and {Y v5 , Y p5} for the target electric power P 1 .

[0036] During a second step E2, the control module MOD determines, for each target electrical power P 1 , P 2 , ... P n and among the first iso-power points Y p , Y v of each set Y1, Y2, ... Yn, the first iso-power point INF(Y p , Y v ) having a maximum slope break in absolute value, called point INF(Y p , Y v ) of optimum adjustment of each target electrical power P 1 , P 2 , ... P n , as represented by way of example in figure 8. Thus, for example for the set Y1 of first iso-power points Y p , Y v , the first iso-power point INF(Y p , Y v ) of optimum adjustment is that of these first iso-power points Y p , Y v which has a maximum slope break in absolute value compared to the neighboring first iso-power points Y p , Y v , each slope joining each first iso-power point Y p , Y v to its neighboring first iso-power point Y p , Y v . According to a first possibility, the control module MOD determines the first iso-power point INF(Y p , Y v ) of optimum adjustment by detecting, for each first iso-power point INF(Y p , Y v ), whether the change in slope is greater than a prescribed slope value, having been set by the user on the interface INT1 of the control module MOD.

[0037] The number n of target electrical powers P 1 , P 2 , ... P n may for example be greater than or equal to 2 or 5 or others, and may for example be less than or equal to 10 or even greater than or equal to 10. The number of first iso-power points Y p , Y v in each set Y1, Y2, ... Yn may for example be greater than or equal to 2 or 3 or others, and may for example be less than or equal to 8 or even greater than or equal to 8. Each target electrical power P 1 , P 2 , ... P n is greater than or equal to a minimum permissible power prescribed for the proper operation of the turbine 1 for a given head height H and is less than or equal to a maximum power prescribed for the proper operation of the turbine 1 for a given head height H.

[0038] During a third step E3, the control module MOD records in its memory MEM or database MEM the optimum adjustment points INF(Y p , Y v ) for the plurality of target electrical powers P 1 , P 2 , ... P n of the turbine 1.

[0039] The optimum adjustment points INF(Y p , Y v ) for the plurality of target electrical powers P 1 , P 2 , ... P n of the turbine 1 form an optimal law (or optimal cam) for the combination of the blades 12 and the guide vanes 14.

[0040] The conjugation cams (or laws) are the laws of the best combinations of the first command Y p for orientation of the blades 12 of the regulating member 121 and first values ​​of the second command Y v for orientation of the guide vanes 14 for fluid control of the regulating member 141 at a given drop height H, making it possible to maximize the overall efficiency of the turbine 1 for each flow rate of the turbine 1.

[0041] The efficiency of turbine 1 can be described using the following hydraulic turbomachinery equations for a given head H: P hyd = ρ . g . Q . H P roue = η roue . P hyd P m é ca = η m é ca . P roue P = η g é n . P m é ca

[0042] More generally, the overall performance of a turbine, in other words its overall efficiency η tur is written with the following equation: η tur = P P hyd that is, by replacing P and combining eq 2 and eq 3 , it comes η tur = η g é n × η m é ca × η roue with P hyd: Hydraulic power, P wheel: Power at the wheel of blades 12, η wheel : Efficiency of the blade wheel 12, P mech: Mechanical power at shaft 11 of turbine 1, η mechanics : mechanical efficiency of turbine 1, P: Electrical power of turbine 1, η gen : Efficiency of the generator of turbine 1, Q: flow rate of the fluid in turbine 1, ρ: density of the fluid in turbine 1, g: acceleration of gravity.

[0043] The invention makes it possible to obtain the conjugation cams of the settings Y p , Y v of the blades 12 and the guide vanes 14 without having to measure the flow rate of the turbine 1 for each of these settings Y p , Y v .

[0044] Indeed, measuring the flow rate Q of the fluid can be difficult to obtain, for example due to the accessibility to the flow measurement sections (fluid flow section or areas where the measurement sensor installation points are located), the available distance from straight sections on the hydraulic circuit, etc. In addition, the installation of flow measurement means can be risky in terms of personal safety depending on the accessibility of the measurement sections. Measuring the flow rate Q of the fluid can also be expensive in terms of equipment: depending on the design of the facilities, a trolley may be necessary for the implementation of the flow sensors, which must be multiplied in number according to the flow section. In some cases, the condition of the pressure taps also has a preponderant weight on the reliability and consistency of the results obtained. Such a flow measurement installation mobilizes human resources and remains, however, unreliable.Indeed, depending on the layout, the geometry of the flow measurement sections is not always verifiable (impossibility of taking geometric readings, combined with old or even incomplete plans) or includes geometric singularities requiring measurement corrections; the distance between the turbine and the flow measurement section may be insufficient and does not allow the fluid to have an ideally laminar behavior avoiding hydraulic turbulence harmful to the measurement. The reliability of flow measurements also depends on measurement uncertainties and metrological monitoring of the sensors involved in the measurement.

[0045] Steps E1, E2 and E3 can be performed for at least one given head height H of the turbine 1, and for example for a single given head height H or for each of several different given head heights H. The head height H is defined by the difference in height between, on the one hand, a first fluid load line (for example water) located in the fluid inlet path 101 and a second fluid load line located in the fluid outlet path 103. The optimum adjustment points INF(Y p , Y v ) for the plurality of target electrical powers P 1 , P 2 , ... P n of the turbine 1 can therefore form the optimal law (or optimal cam) for conjugation of the blades 12 and the guide vanes 14 for at least one given head height H of the turbine 1, or for each of several different given head heights H.

[0046] In a first embodiment, shown in figures 7 , 8 , 9 ,10 And 11 , the first step E1 may include the sub-steps described below.

[0047] During a first sub-step E11 of the first step E1, a first starting conjugation law L1(Y p , Y v ) is entered into the control module MOD, giving the first command Y p for orientation of the blades 12 as a function of the second command Y v for orientation of the fluid control guide vanes 14. The starting conjugation law L1(Y p , Y v ) corresponding to an initial programming of an automaton AUT for controlling the turbine 1 for at least one given head height H of the turbine or for each of the different given head heights H. The first starting conjugation law L1(Y p , Y v ) is prescribed and pre-recorded in the memory MEM or database MEM of the control module MOD.The first substep E11 may comprise measuring by a first sensor CAP12, which is provided on or in the turbine 1 and which is connected to the data input interface INT of the control module MOD, the first orientation ANGP for the first command Y p of orientation of the blades 12 at 0% and for the first command Y p of orientation of the blades 12 at 100%. The first substep E11 may comprise measuring by a second sensor CAP14 of the turbine 1, which is provided on or in the turbine 1 and which is connected to the data input interface INT of the control module MOD, the second orientation ANGV for the second command Y v of orientation of the guide vanes 14 for fluid control at 0% and for the second command Y v of orientation of the guide vanes 14 for fluid control at 100%.

[0048] During a second sub-step E12 of the first step E1, the control module MOD calculates a grid of second points P2 located in a prescribed envelope ENV around the starting conjugation law L1(Y p , Y v ), as shown as an example in figure 9 . The second points P2 have coordinates Y p,j and Y v,i for i ranging from 1 to N and for j ranging from 1 to M, where Y p,j is the first command Y p for orientation of the blades 12, Y v,i is the second command Y v for orientation of the fluid control guide vanes 14, N is a first prescribed natural integer, greater than or equal to 2, M is a second prescribed natural integer, greater than or equal to 2. The integer N can be equal to M or be different from M. The command module MOD can calculate as many grids of second points P2 as there are drop heights H.

[0049] The integer N may be greater than or equal to 4 or 5 and less than or equal to 10. The invention may also be applied to values ​​of N less than 4 or greater than 10.

[0050] The integer M may be greater than or equal to 4 or 5 and less than or equal to 10. The invention may also be applied to values ​​of M less than 4 or greater than 10.

[0051] The second points P2 of the grid are spaced at a prescribed pitch δ (non-zero) along the second command Y v for orientation of the fluid control guide vanes 14. We therefore have Y v,i+1 = Y v,i + δ.

[0052] The second points P2 of the grid are spaced at a prescribed pitch δ' (non-zero) along the first blade orientation command Y p 12. We therefore have: Y p,i+1 = Y p,i + δ'. ​​The pitch δ' can be equal to the pitch δ or be different from the pitch δ.

[0053] The prescribed envelope ENV around the starting conjugation law L1(Y p , Y v ) may be formed by an area between a lower envelope curve ENV1 and an upper envelope curve ENV2. The lower envelope curve ENV1 is an increasing function of Y p as a function of Y v and is located below the starting conjugation law L1(Y p , Y v ). The upper envelope curve ENV2 is another increasing function of Y p as a function of Y v and is located above the starting conjugation law L1(Y p , Y v ). For example, the lower envelope curve ENV1 corresponds to the starting conjugation law L1(Y p , Y v ), having been shifted by a first prescribed shift downwards according to the first blade orientation command Y p of the blades 12.For example, the upper envelope curve ENV2 corresponds to the starting conjugation law L1(Y p , Y v ), having been shifted by a second prescribed shift upwards according to the first blade orientation command Y p 12. The first shift can be equal in absolute value to the second shift. Of course, the envelope curves ENV1 and ENV2 could be different from the starting conjugation law L1(Y p , Y v ) having been shifted.

[0054] During a third sub-step E13 of the first step E1, the control MOD module obtains the flow rate of turbine 1 for each second point P2 from a second prescribed law, giving the value of the flow rate Q(Y p,j , Y v,i ) of turbine 1 as a function of Y p,j and Y v,i . The second law is prescribed in the control MOD module and may have been entered into the control MOD module. For example, the second law may have been obtained from previously recorded flow rate measurements of turbine 1 or from charts giving the measured flow rate of turbine 1, for certain values ​​of the first command Y p for orientation of blades 12 and / or of the second command Y' v,i for orientation of guide vanes 14 for fluid control, or from a model of the flow rate for certain values ​​of the first command Y p for orientation of blades 12 and / or of the second command Y' v,i for orientation of guide vanes 14 for fluid control.The second law can be, for example, in the form of one or more 3-dimensional tables. Thus, the method according to the invention does without real-time measurement of the fluid flow rate in the turbine 1, but relies on pre-recorded flow rate measurements.

[0055] During a fourth sub-step E14 of the first step E1, the control module MOD selects, for each second point P2 having the coordinates Y p,j and Y v,i for i ranging from 1 to N and for j ranging from 1 to M, a third point P3 having coordinates Y' p,j and Y' v,i which correspond to those of the coordinates Y p,j and Y v,i which meet the criterion of the minimum in absolute value between the flow rate of each second point P2 and the flow rate of the neighboring second points P2. Each third point P3 therefore minimizes the variation in the flow rate Q. This advantageously makes it possible to preserve the facilities, the equipment and the safety of third parties during the operation of the control module MOD. The coordinate Y' p,j is the first command Y p for orientation of the blades 12. The coordinate Y' v,i is the second command Y v for orientation of the fluid control guide vanes 14.The command MOD module thus selects for each second point P2 the third neighboring point P3 which meets the following criterion, calculated by the command MOD module: . min Q Y vi + 1 Y pj − Q Y vi , Y pj Q Y vi + 1 Y pj + 1 − Q Y vi , Y pj ; Q Y vi Y pj + 1 − Q Y vi , Y pj ; Q Y vi Y pj − 1 − Q Y vi , Y pj ; Q Y vi + 1 Y pj − 1 − Q Y vi , Y pj ; Q Y vi − 1 Y pj + 1 − Q Y vi , Y pj ; ; Q Y vi − 1 Y pj − Q Y vi , Y pj ; Q Y vi − 1 Y pj − 1 − Q Y vi , Y pj ; , where min denotes the minimum of this set between {}. The control module MOD thus carries out an automatic exploration, point P2 after point P2, of the grid to select the points P3 among the points P2. This automatic exploration is also called routine. The starting point P2 of the routine can be for example the first minimum opening of the blades 12 at 0% and the second minimum opening at 0% of the guide vanes 11, for the turbine 1 considered. The starting point P2 of the routine could be for example the first maximum opening of the blades 12 at 100% and the second maximum opening of the guide vanes 11 at 100%, for the turbine 1 considered.

[0056] During a fifth sub-step E15 of the first step E1, the control module MOD sets (or sends) to the turbine 1, via the data output interface INT3 of the MOD module connected to the regulating members 121 and 141, for one or each of the given drop heights H, the second command Y' v,i for orientation of the fluid control guide vanes 14, associated with the first command Y' p,j for orientation of the blades 12 according to each third point P3.

[0057] The modification of the second command Y' v,i for the orientation of the fluid control guide vanes 14 of the regulating member 141 and of the first command Y' p,j for the orientation of the blades 12 of the regulating member 121 is carried out automatically by the control module MOD according to criteria of waiting time, stabilization and recording of the data during the execution of the routine for positioning at the third point P3.

[0058] According to one possibility, a so-called step-by-step mode, according to the routine, allows to pass from a second command Y' v,i to another and from a first command Y' p,j to another on instruction entered by the user on the INT1 interface of the MOD control module (the next point P3 to be tested being always designated by the MOD module according to the criterion described previously). The routine can be interrupted (and restarted) at any time for reasons of safety and preservation of the turbine 1 tested as well as for the proper operation of the hydraulic system.

[0059] Alternatively, an automatic mode, according to the routine, allows switching from a second command Y' v,i to another and from a first command Y' p,j to another automatically in a manner programmed in the command MOD module.

[0060] The control module MOD can switch from a second command Y' v,i to a first command Y' p,j either simultaneously or one after the other, depending on the control technology of the turbine tested 1.

[0061] Then, during the fifth sub-step E15, a power measuring member or sensor CAPP provided on the turbine 1 measures an electrical power P produced by the turbine 1 (for example by measuring an electrical voltage V produced by the turbine 1 and by measuring an electrical current I produced by the turbine 1, the measuring sensor CAPP being able to comprise an active power transducer TPA, as shown by way of example the figure 7) for each third point P3. The electrical power P measured by the measurement sensor CAPP is sent to the control module MOD, comprising an interface INT2 for receiving data from this measured electrical power P, this reception interface INT2 being connected to the measurement sensor CAPP. The control module MOD records quadruplets (Y' p,j , Y' v,i , H, P) of data giving in association the first command Y' p,j for orientation of the blades 12, the second command Y' v,i for orientation of the fluid control guide vanes 14, the at least one given drop height H and the electrical power P having been measured and corresponding to each third point P3, in the memory MEM or database MEM.

[0062] During a sixth sub-step E16 of the first step E1, the control module MOD determines from the quadruplets (Y' p,j , Y' v,i , H, P) of data the target electrical powers P 1 , P 2 , ... P n and the first iso-power points Y p , Y v associated with the target electrical powers P 1 , P 2 , ... P n (first sets Y1, Y2, ... Yn).

[0063] For example, in a first case, the target electrical powers P 1 , P 2 , ... P n can be equal to the electrical powers P having been measured and corresponding to the third points P3.

[0064] For example, in a second case, the control module MOD calculates during the sixth sub-step E16 the target electrical powers P 1 , P 2 , ... P n and the first iso-power points Y p , Y v by interpolation from the quadruplets (Y' p,j , Y' v,i , H, P) of data.

[0065] For example, in a second case, each target power P 1 , P 2 , ... P n can be prescribed in the control MOD module. The control MOD module can sort the quadruplets (Y' p,j , Y' v,i , H, P) of data according to the electrical powers P. In the case where each target power P 1 , P 2 , ... P n has been prescribed in the control MOD module, the control MOD module can retain for this target power P 1 , P 2 , ... P n the quadruplet (Y' p,j , Y' v,i , H, P) of data, the measured power P of which is closest to the target power P 1 , P 2 , ... P n , for example to within plus or minus a predetermined value ΔP.

[0066] At the end of sub-step E16, the control module MOD performs the second step E2 described above to determine the points INF(Y p , Y v ) for optimum adjustment of the target electrical powers P 1 , P 2 , ... P n .

[0067] In a second embodiment, shown in figures 7, 8 , 11 And 12 , the first step E1 may include the sub-steps described below.

[0068] During another first sub-step E11' of the first step E1, for each of the target electrical powers P 1 , P 2 , ... P n the control module MOD sets (or sends) to the turbine 1 via the data output interface INT3 of the MOD module connected to the regulating members 121 and 141, for one or each of the given drop heights H the first command Y p for orientation of the blades 12 successively to a first selected value Y pr of adjustment from among several first prescribed values ​​Y pr1 , Y pr2 , ... , Y prK of adjustment of the first command Y p for orientation of the blades 12 (for example with a prescribed and non-zero step δ" between these first prescribed values ​​Y pr1 , Y pr2 , ... , Y prK of adjustment).

[0069] Then, during the other first sub-step E11', the power measuring member or sensor CAPP provided on the turbine 1 measures an electrical power P produced by the turbine 1 (for example by measuring an electrical voltage V produced by the turbine 1 and by measuring an electrical current I produced by the turbine 1, the measuring sensor CAPP being able to comprise an active power transducer TPA, as shown by way of example in figure 7 ). The electrical power P measured by the CAPP measuring sensor is sent to the control module MOD, comprising an INT2 interface for receiving data from this measured electrical power P, this INT2 receiving interface being connected to the CAPP measuring sensor.

[0070] Then, during the other first sub-step E11', for each target electrical power P s equal to one of P 1 , P 2 , ... P n (for the integer s ranging from 1 to n), the control module MOD adjusts (or sends) to the turbine 1 via the data output interface INT3 of the MOD module connected to the regulating members 121 and 141, for each first selected value Y pr for adjusting the first command Y p for orientation of the blades 12 and for each given height H of fall of the turbine 1, the second command Y v for orientation of the guide vanes 14 for fluid control successively to a second selected value Y vr for adjustment from among several second prescribed values ​​Y vr1 , Y vr2 , ... , Y vrL for adjustment of the second command Y v for orientation of the guide vanes 14 for fluid control (for example with a prescribed and non-zero pitch δ‴ between these second prescribed values ​​Y vr1 , Y vr2 , ..., Y vrL setting), until the electrical power P measured on turbine 1 is equal to the target electrical power P s , for example to plus or minus a predetermined value ΔP.

[0071] During another second sub-step E12' of the first step E1, the control module MOD records in its database MEM quadruplets (Y pr , H, P s , Y vr ) of data giving each first selected value Y pr for setting the first command Y p for orientation of the blades 12 in association with the at least one given head height H of the turbine 1, with the target electrical power P s equal to one of P 1 , P 2 , ... P n (for the integer s ranging from 1 to n) and with the second selected value Y vr for setting the second command Y v for orientation of the fluid control guide vanes 14, for which the electrical power measured on the turbine 1 is equal to the target electrical power P s .

[0072] During another third sub-step E13' of the first step E1, the control module MOD determines from the quadruplets (Y pr , H, P s , Y vr ) of data the target electrical powers P 1 , P 2 , ... P n and the first iso-power points Y p , Y v associated with the target electrical powers P 1 , P 2 , ... P n (first sets Y1, Y2, ... Yn).

[0073] For example, each target power P 1 , P 2 , ... P n can be prescribed in the control MOD module. The control MOD module can perform sorting of the quadruplets (Y pr , H, P s , Y vr ) of data according to the target electric powers P s .

[0074] At the end of sub-step E13', the control module MOD performs the second step E2 described above to determine the points INF(Y p , Y v ) for optimum adjustment of the target electrical powers P 1 , P 2 , ... P n .

[0075] The MOD control module can be portable and can be added or connected to the AUT control automaton of turbine 1 (control-command of turbine 1). The MOD control module allows both to control turbine 1 by controlling the regulating members 121 and 141, and to collect and analyze the data for the search and optimization of the conjugation cams automatically.

[0076] The invention makes it possible to supply the conjugation cams more quickly than with the standardized method and flow measurement, with a greatly reduced impact on the operation and availability of the turbines on the electrical network. The deployment of the MOD module can be considered rapid on the tested turbines and requires a limited mobilization of resources for implementation (1 person compared to 2 to 4 people for a standardized IEC60041 flow measurement (mill, piezometric control, etc.); the operating constraints are also limited in time. The results (i.e. the laws or conjugation cams) for a given turbine resulting from the use of this MOD module make it possible to ensure sustainable and optimal operation of these turbines, with a guarantee of hydromechanical durability. The MOD module is compatible and adaptable to any AUT automation of double-regulated reaction turbines that we wish to optimize and operate at their best operating points.The MOD module allows the turbine to be controlled while collecting and recording data from which it will be possible to determine and optimize these conjugation laws (or cams).

[0077] The advantages of the invention include in particular: No flow measurement required, Less impact on production for the installation of the module, Limited impact on the operation of the turbine and associated facilities Time saved to obtain reliable results that can be implemented almost immediately in their automation systems, Optimization and therefore gain in production capacity and guaranteed hydromechanical sustainability, Can be used as a diagnostic tool (evolution of laws or conjugation cams, detection of mechanical wear, etc.).

[0078] Of course, the embodiments, features, possibilities and examples described above can be combined with each other or selected independently of each other.
