[0024] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of this application, including various details to aid understanding. These should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0025] The following describes in detail the operation control method of the dual-rotor wind turbine of this application using an embodiment.

[0026] Figure 1 A flowchart illustrating the operation control method for a dual-rotor wind turbine provided in this application embodiment.

[0027] like Figure 1 As shown, the operation control method for a dual-rotor wind turbine proposed in this embodiment specifically includes the following steps:

[0028] S101. Obtain the power deviation of the wind turbine generator set, and based on the power deviation, obtain the first electromagnetic torque compensation value of the front wind turbine generator and the second electromagnetic torque compensation value of the rear wind turbine generator.

[0029] It should be noted that the first power deviation of the front wind turbine generator and the second power deviation of the rear wind turbine generator can be obtained. Based on the first power deviation, the first electromagnetic torque compensation value of the front wind turbine generator can be obtained, and based on the second power deviation, the second electromagnetic torque compensation value of the rear wind turbine generator can be obtained.

[0030] It should be noted that in the relevant technologies, the main control strategy of wind turbines relies solely on the generator speed as the control variable of the unit. However, in actual operation, the rear rotor of a dual-rotor wind turbine is subject to many constraints. Therefore, relying solely on the generator speed as the control variable cannot accurately track changes in wind speed and the speed of the front rotor.

[0031] Therefore, this application proposes an operation control method for a dual-rotor wind turbine, which uses the rotational speed and output power of the front and rear rotors as calculation variables for the control of the front and rear rotor generators. A power feedback control command is added on top of the basic torque. Furthermore, the compensation value corresponding to the power feedback control command is further modified, and then the front and rear rotors are controlled according to the final generated command.

[0032] The first power deviation refers to the deviation of the output power of the front wind turbine generator from the target power of the front wind turbine generator.

[0033] It should be noted that the target power of the front wind turbine generator can be obtained based on the attributes of the wind turbine unit.

[0034] In this embodiment of the application, after obtaining the first power deviation, that is, after obtaining the power feedback control basis for the front wind turbine generator, the first electromagnetic torque compensation value for electromagnetic torque compensation of the front wind turbine generator can be obtained based on the first power deviation.

[0035] It should be noted that this application does not limit the specific method for obtaining the first electromagnetic torque compensation value of the front wind turbine generator based on the first power deviation, and it can be selected according to the actual situation.

[0036] Optionally, after obtaining the first power deviation, the control parameters of the controller corresponding to the wind turbine can be combined to obtain the first electromagnetic torque compensation value of the front wind turbine generator.

[0037] The second power deviation refers to the deviation of the output power of the rear wind turbine generator from the target power of the rear wind turbine generator.

[0038] In this embodiment of the application, after obtaining the second power deviation, that is, after obtaining the power feedback control basis for the rear wind turbine generator, the second electromagnetic torque compensation value for electromagnetic torque compensation of the rear wind turbine generator can be obtained based on the second power deviation.

[0039] It should be noted that, since there is a power deviation between the rear wind turbine generator and the front wind turbine generator, in this application, a power feedback control compensation command for the rear wind turbine speed can be further added on the basis of the basic electromagnetic torque, that is, the power deviation between the rear wind turbine generator and the front wind turbine generator, in order to obtain the second electromagnetic torque compensation value of the rear wind turbine generator.

[0040] It should be noted that this application does not limit the specific method for obtaining the second electromagnetic torque compensation value of the rear wind turbine generator based on the second power deviation, and it can be selected according to the actual situation.

[0041] Optionally, after obtaining the second power deviation, the control parameters of the controller corresponding to the wind turbine can be combined to obtain the second electromagnetic torque compensation value of the front wind turbine generator.

[0042] S102. Correct the first electromagnetic torque compensation value to obtain the first target electromagnetic torque correction compensation value, and correct the second electromagnetic torque compensation value to obtain the second target electromagnetic torque correction compensation value.

[0043] In this embodiment, after obtaining the first electromagnetic torque compensation value and the second electromagnetic torque compensation value, the first electromagnetic torque compensation value and the second electromagnetic torque compensation value can be corrected to obtain the first target electromagnetic torque compensation value ΔT. e1* Second target electromagnetic torque compensation value ΔT e2* .

[0044] It should be noted that the specific method of modifying the first electromagnetic torque compensation value to obtain the first target electromagnetic torque compensation value and modifying the second electromagnetic torque compensation value to obtain the second target electromagnetic torque compensation value is not limited and can be selected according to the actual situation.

[0045] Optionally, an electromagnetic torque correction model can be used to obtain a first target electromagnetic torque compensation value and a second electromagnetic target electromagnetic torque compensation value.

[0046] S103. Obtain the first basic electromagnetic torque of the front wind turbine generator and the second basic electromagnetic torque of the rear wind turbine generator.

[0047] Among them, the first basic electromagnetic torque refers to the basic electromagnetic torque corresponding to the front wind turbine generator. Electromagnetic torque refers to the rotational torque formed on the rotor by the interaction of the magnetic flux of each pole of the generator's rotating magnetic field and the rotor current.

[0048] The second basic electromagnetic torque refers to the basic electromagnetic torque corresponding to the rear wind turbine generator. Electromagnetic torque refers to the rotational torque formed on the rotor by the interaction of the magnetic flux of each pole of the generator's rotating magnetic field and the rotor current.

[0049] It should be noted that this application does not limit the specific method for obtaining the first foundation electromagnetic torque compensation value of the front wind turbine generator and the second foundation electromagnetic torque compensation value of the rear wind turbine generator, and the method can be selected according to the actual situation.

[0050] Optionally, the attribute parameters of the dual wind turbine generator set can be obtained, and the first basic electromagnetic torque compensation value of the front wind turbine generator and the second basic electromagnetic torque compensation value of the rear wind turbine generator can be obtained based on the attribute parameters.

[0051] S104. Obtain the speed deviation of the rear wind turbine generator, and based on the speed deviation, obtain the third electromagnetic torque compensation value of the rear wind turbine generator.

[0052] Among them, the speed deviation refers to the speed deviation of the rear wind turbine generator relative to the front wind turbine generator.

[0053] It should be noted that, since the incoming wind speed passes through the front and rear wind turbine generators at different times, that is, there is a certain time interval between the incoming wind speed passing through the front and rear wind turbine generators, there is a speed deviation between the rear wind turbine generator and the front wind turbine generator. Therefore, in this application, a feedback control compensation command for the front wind turbine generator can be further added on the basis of the basic electromagnetic torque, that is, the speed deviation between the rear wind turbine generator and the front wind turbine generator, so as to obtain the third electromagnetic torque compensation value of the rear wind turbine generator.

[0054] It should be noted that this application does not limit the specific method for obtaining the third electromagnetic torque compensation value of the rear wind turbine generator based on the speed deviation, and it can be selected according to the actual situation.

[0055] Optionally, after obtaining the speed deviation, the control parameters of the controller corresponding to the wind turbine can be combined to obtain the third electromagnetic torque compensation value of the rear wind turbine generator.

[0056] S105. Based on the first basic electromagnetic torque and the first target electromagnetic torque correction compensation value, generate the front wind turbine electromagnetic torque command, and based on the second basic electromagnetic torque, the second target electromagnetic torque correction compensation value and the third electromagnetic torque compensation value, generate the rear wind turbine electromagnetic torque command, so as to control the operation of the wind turbine unit according to the front wind turbine electromagnetic torque command and the rear wind turbine electromagnetic torque command.

[0057] Therefore, according to steps S101 to S104, for the front wind turbine generator, a first target electromagnetic torque compensation value based on power feedback and a first basic electromagnetic torque compensation value based on the basic torque command are obtained; for the rear wind turbine generator, a second target electromagnetic torque compensation value based on power feedback, a second basic electromagnetic torque compensation value based on the basic torque command, and a third electromagnetic torque compensation value based on speed feedback are obtained. Thus, in this embodiment of the application, a front wind turbine electromagnetic torque command can be generated based on the basic electromagnetic torque compensation value and the first target electromagnetic torque compensation value, and a rear wind turbine electromagnetic torque command can be generated based on the second basic electromagnetic torque compensation value, the second target electromagnetic torque compensation value, and the third electromagnetic torque compensation value.

[0058] Furthermore, after generating the electromagnetic torque commands for the front and rear wind turbines, the wind turbine generator can be controlled based on these commands.

[0059] The operation control method for a dual-rotor wind turbine provided in this application obtains the power deviation of the wind turbine, and based on the power deviation, obtains a first electromagnetic torque compensation value for the front wind turbine generator and a second electromagnetic torque compensation value for the rear wind turbine generator. The first electromagnetic torque compensation value is corrected to obtain a first target electromagnetic torque correction compensation value, and the second electromagnetic torque compensation value is corrected to obtain a second target electromagnetic torque correction compensation value. The method also obtains a first basic electromagnetic torque for the front wind turbine generator and a second basic electromagnetic torque for the rear wind turbine generator, obtains the speed deviation of the rear wind turbine generator, and based on the speed deviation, obtains a third electromagnetic torque compensation value for the rear wind turbine generator. Based on the first basic electromagnetic torque and the first target electromagnetic torque correction compensation value, a front wind turbine electromagnetic torque command is generated, and based on the second basic electromagnetic torque, the second target electromagnetic torque correction compensation value, and the third electromagnetic torque compensation value, a rear wind turbine electromagnetic torque command is generated. The wind turbine is then operated and controlled according to the front and rear wind turbine electromagnetic torque commands. Therefore, this application comprehensively considers power feedback control compensation and speed feedback control compensation, and modifies the power feedback control compensation to reduce the load when switching the dual-rotor wind turbine. At the same time, it considers the interval time of the incoming wind speed passing through the front and rear rotors to improve the accuracy of the torque command of the rear rotor and ensure the stable operation of the dual-rotor wind turbine.

[0060] As one possible implementation, such as Figure 2 As shown, based on the above steps, the specific process of obtaining the first electromagnetic torque compensation value of the front wind turbine generator and the second electromagnetic torque compensation value of the rear wind turbine generator according to the power deviation in step S101 is explained, including the following steps:

[0061] S201. Obtain the first control parameters of the front rotor controller of the wind turbine, and obtain the first electromagnetic torque compensation value based on the first control parameters and the power deviation.

[0062] It should be noted that the controller corresponding to the wind turbine's front rotor can be a PID controller (proportional-integral-derivative controller), consisting of a proportional unit (P), an integral unit (I), and a derivative unit (D). Correspondingly, the first control parameter of the front rotor controller can be the first proportional coefficient K. p1 First integration time T I1 First differential time T D1 .

[0063] It should be noted that this application does not limit the specific method for obtaining the first control parameters of the wind turbine's front rotor controller, and the method can be selected according to the actual situation.

[0064] Optionally, pre-stored controller parameter information can be read to obtain the first control parameters of the wind turbine's front rotor controller.

[0065] It should be noted that after obtaining the first control parameters and power deviation, the first electromagnetic torque compensation value can be obtained according to the following formula:

[0066]

[0067] Where ΔTe1 is the first electromagnetic torque compensation value, K p1 The first proportionality coefficient, T I1 For the first integration time, T D1 ΔP represents the first differential time and ΔP represents the power deviation.

[0068] S202. Obtain the second control parameters of the rear rotor controller of the wind turbine, and obtain the second electromagnetic torque compensation value based on the second control parameters and the power deviation.

[0069] It should be noted that the controller corresponding to the rear rotor of the wind turbine can be a PID controller (proportional-integral-derivative controller), consisting of a proportional unit (P), an integral unit (I), and a derivative unit (D). Correspondingly, the second control parameter of the rear rotor controller can be the second proportional coefficient K. p2 Second integration time T I2 Second differential time T D2 .

[0070] It should be noted that this application does not limit the specific method for obtaining the second control parameters of the rear rotor controller of the wind turbine, and can be selected according to the actual situation.

[0071] Optionally, pre-stored controller parameter information can be read to obtain the second control parameters of the wind turbine's rotor controller.

[0072] It should be noted that after obtaining the second control parameter and power deviation, the second electromagnetic torque compensation value can be obtained according to the following formula:

[0073]

[0074] Where ΔTe2 is the second electromagnetic torque compensation value, K p2 The second proportionality coefficient, T I2 For the second integration time, T D2 The second differential time is ΔP, and the power deviation is ΔP.

[0075] As one possible implementation, such as Figure 3As shown, based on the above steps, the process of correcting the first electromagnetic torque compensation value in step S102 to obtain the first target electromagnetic torque correction compensation value, and correcting the second electromagnetic torque compensation value to obtain the second target electromagnetic torque correction compensation value, is explained, including the following steps:

[0076] S301. Obtain the first starting speed, first low speed threshold, first high speed threshold and first rated speed corresponding to the front wind turbine generator, and the second starting speed, second low speed threshold, second high speed threshold and second rated speed corresponding to the rear wind turbine generator.

[0077] It should be noted that, in this application, when attempting to obtain the first target electromagnetic torque correction compensation value and the second target electromagnetic torque correction compensation value, at least two intervals, such as three intervals, can be pre-divided using the first starting speed, the first low speed threshold, the first high speed threshold, the first rated speed, and the second starting speed, the second low speed threshold, the second high speed threshold, and the second rated speed as interval thresholds. Then, the first target electromagnetic torque correction compensation value is obtained according to the interval in which the first speed is located, and the second target electromagnetic torque correction compensation value is obtained according to the interval in which the second speed is located.

[0078] The first low speed threshold refers to the speed of the front wind turbine generator at a lower power, and the second low speed threshold refers to the speed of the rear wind turbine generator at a lower power.

[0079] Optionally, based on the attribute information of the wind turbine, the lower power of the front wind turbine generator and the lower power of the rear wind turbine generator can be obtained to obtain the first low speed threshold ω_(1_a) and the second low speed threshold ω_(2_a).

[0080] The first high speed threshold refers to the speed of the front wind turbine generator at a higher power, and the second high speed threshold refers to the speed of the rear wind turbine generator at a higher power.

[0081] Optionally, based on the attribute information of the wind turbine generator, the higher power of the front wind turbine generator and the higher power of the rear wind turbine generator can be obtained to obtain the first high speed threshold ω. 1_b Second highest speed threshold ω 2_b .

[0082] The first rated speed refers to the speed of the front wind turbine generator at the first rated power, and the second rated speed refers to the speed of the rear wind turbine generator at the second rated power.

[0083] Optionally, the first speed of the front wind turbine generator and the second speed of the rear wind turbine generator can be obtained based on the attribute information of the wind turbine generator. The first rated speed ω can be obtained by obtaining the rated power of the front wind turbine generator and the rated power of the rear wind turbine generator. 1_n Second rated speed ω 2_n .

[0084] The first starting speed refers to the speed of the front wind turbine generator when it starts generating electricity from the grid, and the second starting speed refers to the speed of the rear wind turbine generator when it starts generating electricity from the grid.

[0085] S802. Based on the first rotational speed, the first starting rotational speed value, the first low rotational speed threshold, the first high rotational speed threshold, and the first rated rotational speed, obtain the first target electromagnetic torque correction compensation value, and based on the second rotational speed, the second starting rotational speed value, the second low rotational speed threshold, the second high rotational speed threshold, and the second rated rotational speed, obtain the second target electromagnetic torque correction compensation value.

[0086] Optionally, in response to a first rotational speed greater than a first low rotational speed threshold and less than or equal to a first high rotational speed threshold, the first electromagnetic torque compensation value is used as the first target electromagnetic torque correction compensation value, that is: when ω 1_a <ω1≤ω 1_b At that time, the first electromagnetic torque compensation value ΔT e1 The first target electromagnetic torque correction compensation value ΔT e1* .

[0087] Optionally, in response to a first rotational speed being greater than a first starting rotational speed value and less than or equal to a first low rotational speed threshold, or a first rotational speed being greater than a first high rotational speed threshold and less than or equal to a first rated rotational speed, 0 is taken as the first target electromagnetic torque correction compensation value, i.e., ΔT. e1* =0.

[0088] Optionally, in response to the second rotational speed being greater than the second low rotational speed threshold and less than or equal to the second high rotational speed threshold, the second electromagnetic torque compensation value is used as the second target electromagnetic torque correction compensation value, that is: when ω 2_a <ω2≤ω 2_b At that time, the second electromagnetic torque compensation value ΔT e2 The second target electromagnetic torque correction compensation value ΔT e2* .

[0089] Optionally, in response to a second speed value being greater than a second starting speed value and less than or equal to a second low speed threshold, or a second speed value being greater than a second high speed threshold and less than or equal to a second rated speed, 0 is taken as the second target electromagnetic torque correction compensation value, i.e.: ΔT e2* =0.

[0090] It should be noted that the load of a dual-rotor wind turbine varies significantly at low speed thresholds and near rated speed. Therefore, in order to reduce the load during switching of the dual-rotor wind turbine, the electromagnetic torque compensation value needs to be set to zero.

[0091] In summary, based on the first rotational speed, the first starting rotational speed, the first low rotational speed threshold, the first high rotational speed threshold, and the first rated rotational speed, the first target electromagnetic torque correction compensation value ΔT is determined. e1* And based on the second speed value, the second starting speed value, the second low speed threshold, the second high speed threshold, and the second rated speed, the second target electromagnetic torque ΔT is determined. e2* At that time, the following relationship exists:

[0092]

[0093] Where ω1 is the first rotational speed, ω 1_in The first starting speed, ω 1_a For the first low speed threshold, ω 1_b For the first high speed threshold, ω 1_n For the first rated speed, ΔT e1 The second electromagnetic torque compensation value, ΔT e1* This is the correction and compensation value for the first target electromagnetic torque.

[0094]

[0095] Where ω2 is the second rotational speed, ω 2_in For the second starting speed, ω 2_a For the second low speed threshold, ω 2_b The second highest speed threshold, ω 2_n For the second rated speed, ΔT e2 The second electromagnetic torque compensation value, ΔT e2* This is the correction and compensation value for the second target electromagnetic torque.

[0096] As one possible implementation, such as Figure 4 As shown, based on the above steps, the specific process of obtaining the first basic electromagnetic torque of the front wind turbine generator and the second basic electromagnetic torque of the rear wind turbine generator in step S103 is explained, including the following steps:

[0097] S401. Obtain the design parameters corresponding to the wind turbine, and based on the design parameters, obtain the torque control coefficient of the front wind turbine and the torque control coefficient of the rear wind turbine.

[0098] It should be noted that this application does not limit the specific method for obtaining the front and rear wind turbine torque control coefficients, and the method can be selected according to the actual situation.

[0099] Optionally, the front rotor torque control coefficient can be obtained by querying the mapping relationship between the design parameters of the wind turbine and the front rotor torque control coefficient; the rear rotor torque control coefficient can be obtained by querying the mapping relationship between the design parameters of the wind turbine and the rear rotor torque control coefficient.

[0100] S402. Obtain the first basic electromagnetic torque based on the front impeller torque control coefficient, and obtain the second basic electromagnetic torque based on the rear impeller torque control coefficient.

[0101] In this embodiment of the application, after obtaining the front wind turbine torque control coefficient, the first basic electromagnetic torque can be obtained according to the following formula:

[0102]

[0103] Among them, K opt1 For the front wind turbine torque control coefficient, T e1 ω1[n] represents the first basic electromagnetic torque, and ω1[n] represents the speed of the wind turbine at time n.

[0104] In this embodiment of the application, after obtaining the rear wind turbine torque control coefficient, the second basic electromagnetic torque can be obtained according to the following formula:

[0105]

[0106] Among them, K opt2 For the rear wind turbine torque control coefficient, T e2 ω2[n] represents the second basic electromagnetic torque, and ω2[n] represents the wind turbine speed after time n.

[0107] It should be noted that, since the load of a dual (front and rear) wind turbine generator set often changes significantly at low speeds and near rated speeds, in order to reduce the load during unit switching, in this embodiment of the application, the first electromagnetic torque compensation value can be corrected to obtain a first target electromagnetic torque correction compensation value, and the second electromagnetic torque compensation value can be corrected to obtain a second target electromagnetic torque correction compensation value.

[0108] As one possible implementation, such as Figure 5 As shown, based on the above steps, the specific process of obtaining the speed deviation of the rear wind turbine generator in step S104 is explained, including the following steps:

[0109] S501, Obtain the distance between the front and rear wind turbines.

[0110] It should be noted that this application does not limit the specific method for obtaining the distance between the front and rear wind turbines, and the method can be selected according to the actual situation.

[0111] Optionally, the distance between the front and rear rotors can be obtained based on the attribute information of the wind turbine.

[0112] S502. Obtain the first rotational speed of the front wind turbine generator at time n, and based on the first rotational speed and distance, obtain the first relative delayed rotational speed of the front wind turbine generator at time ni, and obtain the second rotational speed of the rear wind turbine generator at time n, where i is a positive integer less than n and n is a positive integer greater than 1.

[0113] It should be noted that this application does not limit the specific method for obtaining the first rotational speed of the front wind turbine generator at time n, and it can be selected according to the actual situation.

[0114] Alternatively, a speed measuring instrument can be used to obtain the first speed of the front wind turbine generator at time n.

[0115] Furthermore, after obtaining the first rotational speed and distance, the first relative delay rotational speed can be obtained based on the first rotational speed and distance.

[0116] S503. Obtain the second target speed of the rear wind turbine generator when the speed of the front wind turbine generator is the first relative delay speed.

[0117] It should be noted that when attempting to obtain the second target speed of the rear wind turbine generator, the second target speed of the rear wind turbine generator when the front wind turbine speed is the first relative delay speed can be calculated using the following formula:

[0118] ω2[n]_Cmd=f(ω1[ni])

[0119] Where ω2[n]_cmd is the second target speed of the rear wind turbine generator, and ω1[ni] is the first relative delay speed of the front wind turbine generator.

[0120] It should be noted that time i is related to the front impeller speed and the incoming air velocity, and the incoming air velocity and the front impeller speed are dynamically adjusted. The higher the incoming air velocity, the smaller i is, and the lower the incoming air velocity, the larger i is.

[0121] In this embodiment of the application, after obtaining the incoming wind speed and the distance between the front and rear impellers, i can be obtained according to the following formula:

[0122] i = D / v

[0123] Where i is the time, D is the distance between the front and rear wind turbines, and v is the incoming wind speed.

[0124] The incoming wind speed v can be obtained by measuring with an anemometer or by estimating the front impeller speed.

[0125] v=f(ω1[n])

[0126] Where ω1[n] is the rotational speed of the front wind turbine generator.

[0127] S504. Based on the second rotational speed and the second target rotational speed, obtain the relative delay target rotational speed deviation, and use the relative delay target rotational speed deviation as the rotational speed deviation.

[0128] In this embodiment of the application, after obtaining the second target rotational speed, the difference between the second rotational speed and the second target rotational speed can be obtained using the following formula to obtain the relative delay target rotational speed deviation:

[0129] Δω2[n]=f(ω1[ni])-ω2[n]

[0130] Where Δω2[n] is the relative delay target speed deviation, ω2[n]_cmd is the second target speed of the rear wind turbine generator, and ω2[n] is the second speed.

[0132] S601. Obtain the third control parameter of the rear rotor controller corresponding to the wind turbine.

[0133] It should be noted that the controller corresponding to the rear rotor of the wind turbine can be a PID controller. Accordingly, the third control parameter of the controller corresponding to the wind turbine can be the third proportional coefficient Kp*, the third integral time TI*, and the third derivative time TD*.

[0134] It should be noted that this application does not limit the specific method for obtaining the third control parameters of the rear rotor controller corresponding to the wind turbine, and the method can be selected according to the actual situation.

[0135] Optionally, pre-stored controller parameter information can be read to obtain the third control parameters of the controller corresponding to the wind turbine.

[0136] S602. Obtain the third electromagnetic torque compensation value based on the speed deviation and the third control parameter.

[0137] It should be noted that after obtaining the third control parameter and the speed deviation (relative to the target speed deviation with delay), the third electromagnetic torque compensation value can be obtained according to the following formula:

[0138]

[0139] Where ΔTe* is the third electromagnetic torque compensation value, Kp* is the third proportional coefficient, TI* is the third integral time, TD* is the third differential time, and Δω 2[n] This refers to the rotational speed deviation (relative to the target rotational speed deviation over time).

[0140] As one possible implementation, such as Figure 7 As shown, based on the above steps, the specific process of generating the front wind turbine electromagnetic torque command based on the first basic electromagnetic torque and the first target electromagnetic torque correction compensation value in step S105, and generating the rear wind turbine electromagnetic torque command based on the second basic electromagnetic torque, the second target electromagnetic torque correction compensation value, and the third electromagnetic torque compensation value, is explained, including the following steps:

[0141] S701. Add the first basic electromagnetic torque and the first target electromagnetic torque correction compensation value to obtain the first target electromagnetic torque corresponding to the front wind turbine generator.

[0142] In this embodiment of the application, after obtaining the first basic electromagnetic torque and the first target electromagnetic torque correction compensation value, the first basic electromagnetic torque and the first target electromagnetic torque correction compensation value can be added together to obtain the first target electromagnetic torque corresponding to the front wind turbine generator, that is: T 1_ T e =T e1 +ΔT e1* Among them, T e1 For the first fundamental electromagnetic torque, ΔT e1* This is the correction and compensation value for the first target electromagnetic torque.

[0143] S702. Generate the electromagnetic torque command for the front wind turbine based on the first target electromagnetic torque.

[0144] In this embodiment of the application, after obtaining the first target electromagnetic torque, a front wind turbine electromagnetic torque command T can be generated. 1_ T e This is to control the front wind turbine generator to operate according to the first target electromagnetic torque.

[0145] S703. Add the second basic electromagnetic torque, the second target electromagnetic torque correction compensation value, and the third electromagnetic torque compensation value to obtain the second target electromagnetic torque corresponding to the rear wind turbine generator.

[0146] In this embodiment of the application, after obtaining the second basic electromagnetic torque, the second target electromagnetic torque correction compensation value, and the third electromagnetic torque compensation value, the second basic electromagnetic torque, the second electromagnetic torque compensation value, and the third electromagnetic torque compensation value can be added together to obtain the second target electromagnetic torque corresponding to the rear wind turbine generator, i.e., T. 2_ T e =T e2+ΔT e2* +ΔT e* Among them, T 2_ T e For the second target electromagnetic torque, T e2 For the second fundamental electromagnetic torque, ΔT e2* The second target electromagnetic torque correction compensation value, ΔT e* This is the third electromagnetic torque compensation value.

[0148] In this embodiment of the application, after obtaining the second target electromagnetic torque, a rear wind turbine electromagnetic torque command T can be generated. 2_ T e This is to control the rear wind turbine generator to operate according to the second target electromagnetic torque.

[0149] It should be noted that, in the embodiments of this application, the incoming wind speed of the wind turbine, the wind turbine rotor start-up determination threshold set, and the wind turbine rotor shutdown determination threshold set can be obtained, so as to generate matching control commands based on the incoming wind speed, the first rotational speed, the second rotational speed, the front rotor start-up determination threshold set, and the rear rotor start-up determination threshold set, so as to control the wind turbine to start and stop according to the control commands.

[0150] As one possible implementation, such as Figure 8 As shown, based on the above steps, the specific process of controlling the wind turbine's start-up and shutdown according to control commands includes the following steps:

[0151] S801, Obtain the incoming wind speed of the wind turbine.

[0152] It should be noted that start-stop control strategies are often only applicable to single-rotor wind turbines. Furthermore, for dual-rotor wind turbines, the start-stop control strategy relies solely on generator speed and incoming wind speed as the conditions for starting and stopping the wind turbine. However, in actual operation, the rear rotor of a dual-rotor wind turbine is subject to many factors, and the incoming wind speed does not directly affect the rear rotor. Therefore, relying solely on generator speed and incoming wind speed cannot be used as the conditions for starting and stopping the unit.

[0153] Incoming air velocity refers to the distance a fluid (wind) travels per unit time.

[0154] Alternatively, an anemometer can be used to obtain the incoming wind speed of the wind turbine.

[0155] S802. Obtain the wind turbine start-up determination threshold set and the wind turbine shutdown determination threshold set for the wind turbine unit.

[0156] It should be noted that the wind turbine start-up determination threshold set includes the front wind turbine start-up determination threshold set and the rear wind turbine start-up determination threshold set, and the wind turbine shutdown determination threshold set includes the front wind turbine shutdown determination threshold set and the rear wind turbine shutdown determination threshold set.

[0157] It should be noted that this application does not limit the specific methods for obtaining the wind turbine start-up and wind turbine shutdown threshold sets, and the methods can be selected according to the actual situation.

[0158] Optionally, the mapping relationship between the front and rear rotors of the wind turbine can be queried during operation, and the rotor start-up and rotor shutdown judgment threshold sets of the wind turbine can be obtained based on the mapping relationship.

[0159] S803 generates matching control commands based on the incoming wind speed, first rotational speed, second rotational speed, front impeller start-up determination threshold set, and rear impeller start-up determination threshold set, so as to control the impeller to start and stop according to the control commands.

[0160] In this embodiment of the application, after obtaining the wind turbine start-up determination threshold set and the wind turbine shutdown determination threshold set, a matching start-up and shutdown control command can be generated based on the incoming wind speed, the first rotational speed, and the second rotational speed.

[0161] Furthermore, after generating matching control commands, the wind turbine can be started and stopped according to the control commands.

[0162] In summary, the control method for dual-rotor wind turbines provided in this application addresses the issue of numerous constraints during operation. For the front rotor, the output power is used as the calculation variable for front rotor generator control, and a power feedback control command is added on top of the basic torque. For the rear rotor, the front rotor speed, rear rotor speed, front rotor power, and rear rotor power are used as the calculation variables for rear rotor torque control, and a front rotor speed feedback control compensation command is added on top of the basic torque command. This improves the accuracy of the rear rotor torque command, enhances the adaptability of the dual-rotor wind turbine to wind speed fluctuations, enables the dual-rotor wind turbine to track wind speed and front rotor speed changes in real time, increases the power generation of the dual-rotor wind turbine, and ensures the stable operation of the dual-rotor wind turbine.
