Detailed Description
The following detailed description is provided to assist the reader in obtaining a thorough understanding of the methods, apparatus, and/or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatus, and/or systems described herein will be apparent after an understanding of the present disclosure. For example, the order of operations described herein is merely an example and is not limited to those set forth herein, but may be altered as will be apparent after an understanding of the disclosure of the application, except for operations that must occur in a specific order. Furthermore, descriptions of features known in the art may be omitted for clarity and conciseness.
According to the embodiment of the disclosure, when the wind generating set triggers stopping under the preset working condition, the given torque is controlled to be executed according to the load reduction torque curve, and the wind generating set converter maintains the working state, so that the output supporting torque is realized, the stopping load of the wind generating set is reduced, and meanwhile, the pitch system is stopped cooperatively according to the fast pitch-withdrawing mode. When the wind generating set finishes executing the down-set torque according to the load-reduction torque curve, controlling the converter of the wind generating set to stop adjusting, thereby finishing the stop of the wind generating set.
FIG. 1 is a flow chart illustrating a method of controlling a wind turbine generator set according to an embodiment of the present disclosure. The control method can be executed by the master control of the wind generating set, and can also be executed by other controllers arranged in the wind generating set.
Referring to fig. 1, in step S101, in response to a wind turbine triggering a shutdown under a preset operating condition, the wind turbine is controlled to enter a load-shedding shutdown mode. The load shedding shutdown mode comprises the following steps: and controlling the wind generating set converter to maintain modulation, and transmitting a torque reference to the wind generating set converter based on a preset load reduction torque curve. Here, the preset working condition may be a working condition that affects a safe shutdown of the wind turbine generator set, which is determined by a fan load simulation method. Therefore, for different types of wind turbine generators, the conditions affecting a safe shutdown of the wind turbine generator may be different from each other. In addition, when a wind turbine generator system fails, a shutdown may be triggered. However, the present disclosure is not limited thereto, and the shutdown may be triggered by a manual trigger, a remote trigger, a single winding fault tolerant trigger, or the like. In other words, the load-shedding shutdown mode is not limited to the working condition requiring safe load shedding, but the corresponding shutdown triggering logic can be added according to the requirement of the wind generating set.
In the off-load shutdown mode, continuous shutdown torque support can be achieved by maintaining modulation commands and torque commands to the wind turbine generator system converter. In particular, controlling the wind turbine generator system converter maintenance modulation may include controlling the wind turbine generator system converter rectification side power module to maintain modulation and controlling the wind turbine generator system converter inversion side power module to cease modulation. On the other hand, the torque reference issued to the wind turbine generator system converter may be gradually reduced based on a preset load-shedding torque curve. The implementation of the torque reference issued to the wind turbine generator system converter based on the preset load-shedding torque curve is specifically described below.
According to the embodiment of the disclosure, the preset load-shedding torque curve may be a rotational speed torque curve determined according to a fan load simulation method, which can ensure safe shutdown of the wind generating set. However, the present disclosure is not limited thereto. For example, the preset load-shedding torque curve may be a rotational speed torque curve obtained by converting a specific power torque curve, a voltage torque curve or a rotational speed power curve, and the specific power torque curve, the voltage torque curve or the rotational speed power curve may be a power torque curve, a voltage torque curve or a rotational speed power curve which is determined according to a fan load simulation method and can ensure safe shutdown of the wind turbine generator set.
Fig. 2 is a diagram illustrating an example of a rotational speed torque curve according to an embodiment of the present disclosure.
Referring to fig. 2, the horizontal axis represents the rotational speed value (i.e., the wind turbine rotational speed value) and the vertical axis represents the torque value (i.e., the torque reference issued to the wind turbine converter). Meanwhile, the time required to maintain the torque value corresponding to each rotation speed value in the down-load stop mode is also included under the rotation speed torque curve. The method of determining the rotational speed torque curve is described in detail below.
First, the lowest rotational speed n of the rotational speed torque curve needs to be determined c . Minimum rotation speed n c May be determined as the lowest rotational speed at which the wind turbine converter is capable of performing the reference torque. That is, when the rotational speed of the wind generating set is n c Or greater than n c The converter is capable of executing a reference torque when the wind turbine generator set speed is lower than n c At this time, the converter cannot perform the reference torque. According to embodiments of the present disclosure, the minimum rotational speed n may be determined by means of a simulation evaluation or field measurement c . In addition, with n c The corresponding reference torque may be 5% or 10% of rated torque, but the present disclosure is not limited thereto.
Next, at the lowest rotational speed n c And (3) for starting the rotating speed, setting a rotating speed torque curve, wherein the rotating speed torque curve comprises torque values corresponding to the rotating speed values in the load-reducing stop mode and the time required to maintain the torque value corresponding to each rotating speed value. In the process, the torque value corresponding to each rotating speed value and the torque corresponding to each rotating speed value can be determined according to a fan load simulation methodThe time required for the value to be maintained.
As shown in FIG. 2, T run For torque reference, T, performed prior to the triggering of the load-down mode 1 、T 2 、T 3 、…、T k (not shown) is n for rotational speeds N 、n 1 、n 2 、…、n k+1 (not shown), t 1 For operation at operating point (n N ，T 1 ) Duration t of (t) 2 For operation at operating point (n 1 ，T 2 ) Duration t of (t) k For operation at operating point (n k ，T k+1 ) Is not shown, is not shown. n is n N Is the rated rotation speed of the wind generating set.
Here, the following two points need to be noted. First, the rotational speed torque curve as shown in fig. 2 decreases in a linear manner, but the present disclosure is not limited thereto. In practice, the rotational speed torque curve does not necessarily decrease in a linear manner, but may decrease in a nonlinear manner. Next, the rotational speed torque curve as shown in fig. 2 gradually decreases from the rated rotational speed to the minimum rotational speed, but the present disclosure is not limited thereto. In practice, the rotational speed torque curve may gradually decrease from other rotational speeds than the nominal rotational speed to the lowest rotational speed.
In summary, the rotational speed-torque curve may include a plurality of rotational speed values, a plurality of torque values corresponding to the plurality of rotational speed values, and a time required for maintaining each of the plurality of torque values, where the plurality of torque values represent torque references issued to the wind turbine generator system converter. The rotational speed torque curve gradually decreases from the rated rotational speed of the wind turbine generator system to the lowest rotational speed at which the wind turbine generator system converter is capable of performing the reference torque. Alternatively, the rotational speed torque curve gradually decreases from the nominal rotational speed to the lowest rotational speed in a linear manner or a nonlinear manner.
Referring back to fig. 1, in step S102, the wind turbine generator set is controlled to exit the load shedding mode in response to satisfaction of the load shedding mode end condition. According to an embodiment of the present disclosure, it is determined that a load-shedding shutdown mode end condition is satisfied in response to a wind turbine generator set converter performing a torque reference corresponding to a minimum rotational speed for a time required for the torque reference to be reached. Alternatively, when the wind turbine is controlled to exit the load-down shutdown mode, the wind turbine converter may be controlled to stop modulating (i.e., stop issuing modulation instructions) and to open the circuit breakers of the wind turbine converter (i.e., open the converter grid side circuit breakers and the machine side circuit breakers).
According to the embodiment of the disclosure, in response to the wind generating set triggering a stop under a preset working condition, a pitch system of the wind generating set can be controlled to execute feathering at a preset pitch-receiving speed. Here, the preset pitch speed may be the fastest pitch speed that ensures a safe shutdown of the wind turbine. However, the present disclosure is not limited thereto, and the preset pitch speed may be any pitch speed capable of ensuring a safe shutdown of the wind turbine generator set. In general, to increase the rotational speed reduction speed for a safe and fast shutdown, upon entering the load-shedding shutdown mode, the pitch system of the wind turbine may be controlled to perform feathering at a predetermined pitch speed (e.g., the fastest pitch speed) until the wind turbine is shutdown. That is, after exiting the load-shedding mode, the pitch system of the wind turbine may still be controlled to perform feathering at a predetermined pitch speed.
Fig. 3 is a flowchart illustrating an example of a control method of a wind turbine generator set according to an embodiment of the present disclosure.
Referring to fig. 3, in step S301, it is determined whether the wind turbine generator set enters a down-load shutdown mode. As described above, if the wind turbine generator system triggers a shutdown under a preset working condition, the wind turbine generator system will enter a load-shedding shutdown mode, otherwise, step S301 will be repeatedly performed.
When the wind turbine enters the down-load shutdown mode, in step S302, the wind turbine converter modulation is maintained, and in step S303, the pitch system of the wind turbine is controlled to perform minimum time feathering (i.e., the pitch system is controlled to perform feathering at the fastest closing speed).
Next, in step S304, it is determined whether the execution of the rotational speed torque curve is completed, that is, whether the issuing of the torque reference is completed in accordance with the rotational speed torque curve. As described above, the rotational speed torque curve gradually decreases from the rated rotational speed of the wind turbine generator system to the lowest rotational speed at which the wind turbine generator system converter is capable of performing the reference torque.
When the execution of the rotation speed torque curve is completed, in step S305, the wind turbine generator system is controlled to exit the load-reducing stop mode, otherwise, steps S302 and S303 are executed in a returning manner.
Fig. 4 is a flowchart illustrating another example of a control method of a wind turbine generator set according to an embodiment of the present disclosure.
Referring to fig. 4, in step S401, it is determined whether the wind turbine generator set is in an operating state. If the wind park is in operation, in step S402, it is determined if the wind park triggers a load shedding shutdown mode. As described above, if the wind turbine generator system triggers a shutdown under a preset operating condition, a load-shedding shutdown mode is triggered. If the load-down shutdown mode is triggered, in step S403, the wind turbine generator set converter modulation is maintained, and in step S404, a torque reference is issued to the converter based on the rotational speed torque curve. In step S405, it is determined whether the execution of the rotational speed torque curve is completed. If the execution of the rotation speed torque curve is completed, in step S406, the wind turbine generator set is controlled to exit the load-reducing stop mode, otherwise, the step S404 is executed again. After exiting the load-shedding mode, in step S407, the control converter stops modulating and opens the circuit breaker of the converter. On the other hand, when the load-down stop mode is triggered, the pitch system of the wind turbine generator system is controlled to perform the shortest time feathering in step S408, and the feathering operation is completed in step S409. Thereafter, in step S410, the wind turbine generator system is completely shut down. Here, it is to be noted that although step S410 is shown in fig. 4 as being performed after step S407, the precondition for performing step S410 is to complete the feathering operation (i.e., step S409) instead of controlling the current transformer to stop modulation and open the circuit breaker of the current transformer (i.e., step S407).
Fig. 5 is a block diagram illustrating a controller according to an embodiment of the present disclosure. The controller may be implemented as a master controller or other controller of the wind turbine.
Referring to fig. 5, a controller 500 according to an embodiment of the present disclosure includes a processor 510 and a memory 520. Processor 510 may include, but is not limited to, a Central Processing Unit (CPU), a Digital Signal Processor (DSP), a microcomputer, a Field Programmable Gate Array (FPGA), a system on a chip (SoC), a microprocessor, an Application Specific Integrated Circuit (ASIC), or the like. The memory 520 may store computer programs to be executed by the processor 510. Memory 520 may include high-speed random access memory and/or a non-volatile computer-readable storage medium. When the processor 510 executes a computer program stored in the memory 520, the control method of the wind turbine set as described above may be implemented.
Alternatively, controller 500 may communicate with other various components in the wind park in a wired or wireless communication manner, and may also communicate with other devices in the wind park (e.g., a master controller of the wind park) in a wired or wireless communication manner. Further, the controller 500 may communicate with devices external to the wind farm in a wired or wireless communication.
