[0076] Figure 1 A flow chart of a method for controlling the operation of a fan unit provided in an embodiment of the present application is shown. The fan unit includes a plurality of fans. The method includes:

[0077] Step 101: obtaining a current control speed and a current operating parameter of a target fan, where the target fan is one of the multiple fans;

[0078] Step 102: determining a target control speed of the target fan according to the current control speed and the current operating parameters;

[0079] Step 103: Using the target control speed to control the target fan to operate.

[0080] By acquiring and adjusting the fan control speed in real time, it is ensured that the fan can operate efficiently and stably under different wind speed conditions.

[0081] In a possible implementation manner, in step 102, the current operating parameter includes the current operating speed of the target fan, and determining the target control speed of the target fan according to the current control speed and the current operating parameter includes:

[0082] Obtain the current rated speed and maximum control speed of the target fan, wherein the current rated speed corresponds to the current control speed; determine the target control speed based on the difference between the current rated speed and the current operating speed, and the current control speed is less than the maximum control speed.

[0083] In order to determine the safe operating range of the fan and use it as a basis for adjusting the fan speed, the current rated speed and the maximum control speed are obtained. By comparing the current rated speed with the current operating speed, it can be determined whether the fan is operating at the optimal working point.

[0084] In a possible implementation manner, determining the target control speed according to the difference between the current rated speed and the current operating speed, and the current control speed being less than the maximum control speed, includes:

[0085] According to the fact that the speed difference between the current rated speed and the current operating speed is greater than the speed deviation threshold, and the current control speed is less than the maximum control speed, the target control speed is determined based on the sum of the current control speed and the preset unit speed; or, according to the fact that the speed difference between the current operating speed and the current rated speed is greater than the speed deviation threshold, and the current control speed is less than the maximum control speed, the target control speed is determined based on the difference between the current control speed and the preset unit speed.

[0086] By setting the speed deviation threshold, when the difference between the actual operating speed and the rated speed exceeds this threshold, the control speed of the fan is adjusted. If the difference between the current rated speed and the current operating speed is greater than the speed deviation threshold, and the current control speed has not reached the maximum control speed, then the target control speed is determined based on the sum of the current control speed and the preset unit speed. If the difference between the current operating speed and the current rated speed is greater than the speed deviation threshold, and the current control speed has not reached the maximum control speed, then the target control speed is determined based on the difference between the current control speed and the preset unit speed.

[0087] Assume that when the wind speed of a wind turbine changes, the current operating speed is 950RPM, the current rated speed is 1000RPM, the maximum control speed is 1200RPM, the preset unit speed is 50RPM, and the speed deviation threshold is 30RPM. If the difference between the current operating speed and the rated speed is 50RPM (greater than the threshold 30RPM), and the current control speed (950RPM) does not reach the maximum control speed (1200RPM), the target control speed will be determined based on the sum of the current control speed and the preset unit speed, that is, 950RPM+50RPM=1000RPM. If in another case, the current operating speed is 1050RPM (exceeding the rated speed 1000RPM), the difference is 50RPM (greater than the threshold 30RPM), and the current control speed does not reach the maximum control speed, the target control speed will be determined based on the difference between the current control speed and the preset unit speed, that is, 1050RPM-50RPM=1000RPM. In this way, wind turbines can maintain optimal operating conditions at different wind speeds, which also helps reduce the operation and maintenance costs of wind farms.

[0088] In one possible implementation, the current operating parameters include the current operating current of the target fan. In step 102, determining the target control speed of the target fan based on the current control speed and the current operating parameters includes: obtaining the maximum control speed of the target fan and the current average operating current of the multiple fans; determining the target control speed based on the difference between the current average operating current and the current operating current, and the current control speed being less than the maximum control speed.

[0089] In order to determine the safe operating range of the fan and use it as a benchmark for adjusting the fan speed, the maximum control speed and the current average operating current are obtained; by comparing the current operating current with the average operating current, it is determined whether the fan is operating at the optimal operating point.

[0090] In a possible implementation, the target control speed is determined based on the difference between the current average working current and the current working current, and the current control speed is less than the maximum control speed, including: determining the target control speed based on the sum of the current control speed and a preset unit speed, based on the fact that the current difference between the current average working current and the current working current is greater than a current deviation threshold, and the current control speed is less than the maximum control speed; or determining the target control speed based on the difference between the current control speed and a preset unit speed, based on the fact that the current difference between the current working current and the current average working current is greater than a current deviation threshold, and the current control speed is less than the maximum control speed.

[0091] By setting the current deviation threshold, when the difference between the actual working current and the average working current exceeds this threshold, the control speed of the fan needs to be adjusted. If the difference between the current average working current and the current working current is greater than the current deviation threshold, and the current control speed has not reached the maximum control speed, then the target control speed is determined based on the sum of the current control speed and the preset unit speed. If the difference between the current working current and the current average working current is greater than the current deviation threshold, and the current control speed has not reached the maximum control speed, then the target control speed is determined based on the difference between the current control speed and the preset unit speed.

[0092] Assume that there are multiple wind turbines in a wind farm, the current operating current of one wind turbine is 150A, the average operating current of all wind turbines in the wind farm is 120A, the maximum control speed of the wind turbine is 1200RPM, the preset unit speed is 50RPM, and the current deviation threshold is 20A. If the difference between the average operating current and the current operating current is 30A (150A-120A, greater than the threshold 20A), and the current control speed (e.g. 1000RPM) does not reach the maximum control speed (1200RPM), the target control speed will be determined based on the sum of the current control speed and the preset unit speed, that is, 1000RPM+50RPM=1050RPM. If in another case, the current working current is 90A (less than the average working current 120A), the difference is 30A (120A-90A, greater than the threshold 20A), and the current control speed has not reached the maximum control speed, then the target control speed will be determined based on the difference between the current control speed and the preset unit speed, that is, 1000RPM-50RPM=950RPM. In this way, the wind turbine can maintain the best operating state under different wind speeds and loads, improve power generation efficiency, and help reduce the operation and maintenance costs of the wind farm.

[0093] In a possible implementation, the multiple fans are arranged on the same plane, and an interval between two adjacent fans is less than or equal to an interval threshold.

[0094] According to factors such as the geographical conditions, wind direction and wind speed distribution of the wind farm, an optimal spacing threshold is set to balance the spatial utilization of the wind farm and the influence of the wake effect. The smaller the spacing between wind turbines, the greater the mutual influence between them. Therefore, the control strategy of the wind turbine needs to take into account the coordinated operation of the entire wind farm, not just the optimization of a single wind turbine. By controlling the spacing of wind turbines within a certain range, the spatial utilization of the wind farm can be improved, the number of wind turbines per unit area can be increased, and the total power generation of the wind farm can be increased.

[0095] In a possible implementation, the method further includes: determining a faulty fan from the multiple fans, the faulty fan being a fan that has stopped operating among the multiple fans; obtaining a current medium pressure of a medium associated with the faulty fan based on satisfying a preset condition; the medium is used by the fan to transport gas by doing work on the medium; and restarting the faulty fan based on the current medium pressure and a high pressure threshold range.

[0096] In a possible implementation manner, restarting the faulty fan according to the current medium pressure and the high pressure threshold range includes:

[0097] Obtain the pre-fault operating frequency of the compressor associated with the faulty fan; determine the first debugging operating frequency of the compressor based on the difference between the pre-fault operating frequency of the compressor associated with the faulty fan and a preset unit frequency according to the current medium pressure exceeding the high-pressure threshold range; use the first debugging operating frequency to control the operation of the compressor to restart the faulty fan.

[0098] In a possible implementation, the first debugging operating frequency is used to control the operation of the compressor to restart the faulty fan, including: using the first debugging operating frequency to control the operation of the compressor for a first preset time; based on reaching the first preset time, sending a restart instruction to the faulty fan; based on successful restart of the faulty fan, restoring the operating frequency of the compressor to the operating frequency before the fault; based on failure to restart the faulty fan, determining the second debugging operating frequency of the compressor based on the difference between the first debugging operating frequency and the preset unit frequency, and using the second debugging operating frequency to control the operation of the compressor for the first preset time; and repeating this cycle until the faulty fan is successfully restarted or the frequency of the compressor drops to the lowest safe frequency.

[0099] In a possible implementation, restarting the faulty fan based on the current medium pressure and the high-pressure threshold range includes: obtaining a first current control speed of a first fan based on the current medium pressure being within the high-pressure threshold range, the first fan being any fan other than the faulty fan among the multiple fans; determining a first debugging control speed of the first fan based on a difference between the first current control speed and a preset unit speed; and controlling the operation of the first fan using the first debugging control speed to restart the faulty fan.

[0100] In a possible implementation, the use of the first debugging control speed to control the operation of the first fan to restart the faulty fan includes: using the first debugging control speed to control the operation of the first fan for a second preset time; sending a restart instruction to the faulty fan based on the arrival of the second preset time; based on a successful restart of the faulty fan, restoring the control speed of the first fan to the first current control speed; based on a failed restart of the faulty fan, determining a second debugging control speed based on the difference between the first debugging control speed and the preset unit speed, and using the second debugging control speed to control the operation of the first fan for the second preset time; and repeating this cycle until the faulty fan restarts successfully or the control speed of the first fan drops to the minimum safe speed.

[0101] In a possible implementation manner, before obtaining the current medium pressure of the medium associated with the faulty fan, the method further includes:

[0102] Obtain the number of restarts of the faulty fan within a set monitoring period; if the number of restarts exceeds a set restart threshold, send fault information to a server and stop restarting the faulty fan; if the number of restarts does not exceed the set restart threshold, determine that the preset condition is met.

[0103] Figure 2 A schematic flow chart of another fan unit operation control method provided in an embodiment of the present application, the method comprising:

[0104] Step 201: determining a faulty fan from the multiple fans, wherein the faulty fan is a fan that stops running among the multiple fans;

[0105] Step 202: acquiring the current medium pressure of the medium associated with the faulty fan according to the preset condition being met; the medium is used by the fan to transport gas by doing work on the medium;

[0106] Step 203: restarting the faulty fan according to the current medium pressure and the high pressure threshold range.

[0107] In a possible implementation, before obtaining the current medium pressure of the medium associated with the faulty fan in step 202, the method further includes: obtaining the number of restarts of the faulty fan within a set monitoring period; sending fault information to a server and stopping restarting the faulty fan based on the number of restarts exceeding a set restart threshold; and determining that the preset condition is satisfied based on the number of restarts not exceeding the set restart threshold.

[0108] By monitoring the number of restarts of the wind turbine, it is possible to identify wind turbines with frequent faults and optimize maintenance and repair strategies. Through precise fault monitoring and restart control, unnecessary maintenance work can be reduced and maintenance costs can be reduced. Assuming that wind turbine A in a wind farm stops running, according to the method provided in the embodiment: first determine that wind turbine A is a faulty wind turbine. Check the number of restarts of wind turbine A in the past monitoring period (for example, within 24 hours), assuming it is 1 time. If the set restart threshold is 2 times, the number of restarts of wind turbine A (1 time) does not exceed the threshold, so the preset condition is met. Get the current medium pressure of the medium associated with wind turbine A, assuming it is 0.8MPa. According to the current medium pressure (0.8MPa) and the high pressure threshold range (assuming it is 0.7MPa to 1.0MPa), it is judged that the current pressure is within the safe range and wind turbine A can be restarted. Once the number of restarts exceeds the set threshold, the system will send a fault message to the server in order to notify the maintenance personnel that the wind turbine may have more serious problems and require professional inspection and repair. With this approach, wind farms can effectively control the restart of faulty wind turbines, reduce unnecessary damage and maintenance costs, and improve the operational efficiency and safety of wind farms.

[0109] In a possible implementation, in step 203, restarting the faulty fan according to the current medium pressure and the high-pressure threshold range includes: obtaining the pre-fault operating frequency of the compressor associated with the faulty fan; determining a first debugging operating frequency of the compressor based on the difference between the pre-fault operating frequency of the compressor associated with the faulty fan and a preset unit frequency according to the current medium pressure exceeding the high-pressure threshold range; and controlling the operation of the compressor using the first debugging operating frequency to restart the faulty fan.

[0110] In a possible implementation, the first debugging operating frequency is used to control the operation of the compressor to restart the faulty fan, including: using the first debugging operating frequency to control the operation of the compressor for a first preset time; based on reaching the first preset time, sending a restart instruction to the faulty fan; based on successful restart of the faulty fan, restoring the operating frequency of the compressor to the operating frequency before the fault; based on failure to restart the faulty fan, determining the second debugging operating frequency of the compressor based on the difference between the first debugging operating frequency and the preset unit frequency, and using the second debugging operating frequency to control the operation of the compressor for the first preset time; and repeating this cycle until the faulty fan is successfully restarted or the frequency of the compressor drops to the lowest safe frequency.

[0111] In step 203, the specific implementation method of restarting the faulty fan according to the current medium pressure and the high-pressure threshold range includes: first, obtaining the pre-fault working frequency of the compressor associated with the faulty fan, so that the fan can be restored to the best working state after the fan is successfully restarted. Further, if the current medium pressure exceeds the high-pressure threshold range, the first debugging working frequency of the compressor is determined based on the difference between the pre-fault working frequency and the preset unit frequency. This step is to adjust the compressor to a safer operating frequency before restarting to adapt to the current medium pressure conditions. The first debugging working frequency is further used to control the compressor to run for a certain period of time, and then a restart instruction is sent to the faulty fan. If the fan restarts successfully, the working frequency of the compressor is restored to the working frequency before the fault. If the fan fails to restart, the second debugging working frequency is determined based on the difference between the first debugging working frequency and the preset unit frequency, and the above process is repeated. Repeat until success or the minimum safe frequency is reached: This cycle will continue until the fan is successfully restarted or the frequency of the compressor drops to the minimum safe frequency, ensuring that the fan restarts under safe conditions and avoiding equipment damage caused by frequent restarts.

[0112] Assume that a wind turbine in a wind farm stops running due to excessive medium pressure. According to the above implementation: the operating frequency of the compressor before the failure is 60Hz. The preset unit frequency is 5Hz, and the current medium pressure exceeds the high pressure threshold, so the first debugging operating frequency is 60Hz-5Hz=55Hz. Run the compressor at a frequency of 55Hz for a certain period of time, and then try to restart the wind turbine. If the wind turbine fails to restart successfully, adjust the frequency to 55Hz+5Hz=60Hz, and try again. If the wind turbine restarts successfully, restore the compressor frequency to 60Hz.

[0113] In a possible implementation manner, in step 203, restarting the faulty fan according to the current medium pressure and the high pressure threshold range includes:

[0114] According to the current medium pressure being within the high-pressure threshold range, a first current control speed of the first fan is obtained, where the first fan is any fan other than the faulty fan among the multiple fans; based on the difference between the first current control speed and a preset unit speed, a first debugging control speed of the first fan is determined; and the operation of the first fan is controlled by using the first debugging control speed to restart the faulty fan.

[0115] In a possible implementation manner, the adopting the first debugging to control the rotation speed to control the operation of the first fan to restart the faulty fan includes:

[0116] The first debugging control speed is used to control the first fan to run for a second preset time; based on the arrival of the second preset time, a restart instruction is sent to the faulty fan; based on the successful restart of the faulty fan, the control speed of the first fan is restored to the first current control speed; based on the failure of the restart of the faulty fan, a second debugging control speed is determined based on the difference between the first debugging control speed and the preset unit speed, and the second debugging control speed is used to control the first fan to run for the second preset time; this cycle is repeated until the faulty fan is successfully restarted or the control speed of the first fan drops to the minimum safe speed.

[0117] In step 203, the specific implementation method of restarting the faulty fan according to the current medium pressure and the high-pressure threshold range includes: when the current medium pressure is within the high-pressure threshold range, select a non-faulty fan (the first fan) and obtain its current control speed. Based on the difference between the current control speed of the first fan and the preset unit speed, determine the first debugging control speed of the first fan. Use the first debugging control speed to control the first fan to run for a second preset time, and then send a restart command to the faulty fan. If the faulty fan is restarted successfully, restore the control speed of the first fan to the first current control speed. If the faulty fan fails to restart, determine the second debugging control speed based on the difference between the first debugging control speed and the preset unit speed, and repeat the above process. Repeat until success or the minimum safe speed is reached: This cycle will continue until the faulty fan is successfully restarted or the control speed of the first fan drops to the minimum safe speed.

[0118] Assume that wind turbine A in a wind farm fails, and wind turbine B participates in the restart process as the first wind turbine: Get the current control speed of the first wind turbine: The current control speed of wind turbine B is 1000RPM. The preset unit speed is 50RPM, and the first debugging control speed is 1000RPM-50RPM=950RPM. Run wind turbine B at a frequency of 950RPM for a second preset time, such as 10 minutes, and then try to restart wind turbine A. If wind turbine A restarts successfully, the speed of wind turbine B is restored to 1000RPM. If wind turbine A fails to restart, the first debugging control speed is adjusted to 950RPM+50RPM=1000RPM, run again for 10 minutes, and then try to restart wind turbine A. Through this method of gradually adjusting the speed, the restart process of the wind turbine can be effectively controlled to ensure that the wind turbine restarts under safe conditions, while reducing damage to equipment and maintenance costs. This method reflects the optimization of the wind turbine restart strategy and helps to improve the operating efficiency and stability of the wind farm.

[0119] By determining a faulty fan from the multiple fans, the faulty fan is a fan that has stopped running among the multiple fans; according to satisfying a preset condition, the current medium pressure of the medium associated with the faulty fan is obtained; the medium is used by the fan to transport gas by doing work on the medium; according to the current medium pressure and the high-pressure threshold range, the faulty fan is restarted. By monitoring and determining the faulty fan, problems can be discovered and handled in a timely manner, reducing downtime caused by faults. By monitoring the current medium pressure of the medium associated with the faulty fan and comparing it with the high-pressure threshold range, the operating parameters of the fan unit can be scientifically determined to avoid equipment damage that may be caused by blind restart.

[0120] Figure 3 The schematic diagram of the fan matrix wall is shown, and each fan is marked as A1, A2, ..., AN. The system monitors the current of each fan in real time. Current is an important parameter to measure the working status of the fan, and the load condition of the fan can be indirectly understood through the current. The speed of a motor (such as an induction motor or a permanent magnet motor) is usually determined by the power supply frequency and the number of pole pairs. At a constant power supply frequency, the speed of the motor is fixed. However, in actual applications, the speed of the motor may change due to load changes. In the absence of speed feedback control, if the speed of the fan decreases, it may be because the load increases. In this case, the current of the motor may increase because the motor needs to provide more torque to overcome the increased load. On the contrary, if the speed of the fan increases and the load decreases, the current of the motor may decrease.

[0121] In a multi-fan system, there are usually two situations to monitor and control the operation of the fans:

[0122] The first case: Current monitoring without speed feedback: When the system has no speed feedback signal or the fan does not have a speed sensor, the fan's working status will be indirectly determined by monitoring the fan's current. The magnitude of the current can reflect the load of the fan. If the current of a fan deviates significantly from the average value, it may mean that the load of the fan is too high or too low and needs to be adjusted.

[0123] The second case: Speed ​​monitoring with speed feedback: When the system has speed feedback function, that is, the fan is equipped with a speed sensor, it will directly monitor the actual speed of the fan. By comparing the actual speed with the set rated speed, the system can more directly determine whether the fan is working normally. If there is a large deviation between the actual speed and the rated speed, the system will make corresponding adjustments.

[0124] The control logic of the first case when the fan has no feedback speed specifically includes:

[0125] Step 1: The system monitors and calculates the difference between the average current Ia0 and the real-time current IaN of a specific wind turbine (labeled as AN) in real time.

[0126] Step 2: Determine whether the difference Ia0-IaN is greater than the set allowable deviation value F. If so, proceed to step 3;

[0127] Step 3: Check whether the current control speed QaN of the fan AN has not reached the maximum control speed Qmax. If so, proceed to step 4;

[0128] Step 4: If the difference is greater than F and QaN is less than Qmax, the output speed QaN of the fan AN is increased by a preset unit speed, i.e., QaN=QaN+preset unit speed. If QaN has reached Qmax or the difference is not greater than F, the current speed of the fan AN is maintained unchanged.

[0129] In the first case, another control logic when the fan has no feedback speed includes:

[0130] Step 1: The system monitors and calculates the difference between the real-time current IaN and the average current Ia0 of a specific wind turbine (labeled as AN) in real time.

[0131] Step 2: Determine whether the difference IaN-Ia0 is greater than the set allowable deviation value F.

[0132] Step 3: Check whether the current control speed QaN of the fan AN has not reached the maximum control speed Qmax.

[0133] Step 4: If the difference is greater than F and QaN is less than Qmax, the output speed QaN of the fan AN is reduced by a preset unit speed, i.e., QaN=QaN-preset unit speed. If QaN has reached Qmax or the difference is not greater than F, the current speed of the fan AN is maintained unchanged.

[0134] These two control logics ensure that in the absence of speed feedback, the system can automatically adjust the speed of the wind turbine according to the current difference to maintain speed uniformity among wind turbines and improve the overall efficiency and safety of the wind farm.

[0135] In the second case, the control logic when the fan has feedback speed specifically includes:

[0136] Step 1: The system monitors the actual feedback speed Pa0,1~n of each fan in real time, and obtains the rated speed Ya0,1~n of the fan at the output speed Qa0,1~n.

[0137] Step 2: For each fan, calculate the difference between the actual feedback speed and the rated speed, PaN-YaN.

[0138] Step 3: If the difference PaN-YaN is greater than the preset allowable deviation value G, and the current output speed QAN of the fan has not reached the maximum control speed Qmax, then execute step 4. Otherwise, maintain the status quo.

[0139] Step 4: Reduce the output speed QAN of the fan by 1 unit, that is, QAN=QAN-preset unit speed.

[0140] This control logic ensures that the fan output speed is adjusted according to the difference between the actual feedback speed and the rated speed to keep the fan running in the best state. If the difference exceeds the allowable deviation and the output speed has not reached the maximum value, the system will reduce the output speed to reduce the difference. If the difference is within the allowable range or the output speed has reached the maximum value, no adjustment is made.

[0141] In the second case, the control logic when the fan has feedback speed also includes:

[0142] Step 1: The system monitors the actual feedback speed Pa0,1~n and the rated speed Ya0,1~n under the current control speed Qa0,1~n of each fan in real time.

[0143] Step 2: For each fan, calculate the difference between the rated speed and the actual feedback speed, YaN-PaN.

[0144] Step 3: If the difference YaN-PaN is greater than the preset allowable deviation value G, and the current fan output speed QaN does not reach the maximum control speed Qmax, execute step 4. Otherwise, maintain the status quo, that is, do not adjust the fan output speed.

[0145] Step 4: If the conditions of step 3 are met, the output speed QaN of the fan is increased by a fixed value, that is, QaN=QaN+preset unit speed.

[0146] If the actual feedback speed of the fan is lower than the rated speed by more than the preset allowable deviation value G, and the output speed has not reached the maximum value, the system will increase the output speed to try to make the actual speed close to the rated speed. Such adjustments can help ensure that the fan provides sufficient power when needed while avoiding exceeding the maximum control speed limit.

[0147] The purpose of this logic is to ensure that the actual speed of the fan is as close to its rated speed as possible to maintain the efficiency and stability of the system. By increasing the speed, the system attempts to reduce the deviation between the actual speed and the rated speed. In actual operation, the system will adjust the output of the fan based on these monitoring data to ensure that the operating status of all fans is as consistent as possible, so as to achieve efficient and stable operation of the entire system. This control strategy can be summarized as follows: in the absence of speed feedback, the output of the fan is controlled by adjusting the current. In the case of speed feedback, the output of the fan is controlled by adjusting the speed. The system will select the most appropriate control method according to the actual situation, and may switch between these two control strategies under different operating conditions.

[0148] In another possible implementation, the system is first in a normal control state, and the fan operates according to a predetermined logic. When a fan AN fails, the system will attempt to restart it. The fan fault handling logic specifically includes:

[0149] Step 1: The system first identifies the stopped fan AN and confirms it as a faulty fan. The faulty fan is a fan that has stopped running among the multiple fans;

[0150] Step 2: The system restarts fan AN and checks whether the restart is successful. If the restart fails, proceed to step 3;

[0151] Step 3: The system checks the number of faults of fan AN within the most recent set time. If the number of faults exceeds the set number, the system will stop further restart attempts, because this may mean that there is a more serious problem with the fan and manual intervention or maintenance is required. At this time, the system will report the fault information for subsequent processing. If the number of faults does not exceed the set number, proceed to step 4.

[0152] Step 4-1: High-pressure situation processing: The system obtains the current medium pressure of the medium associated with fan AN. If the current medium pressure Pc exceeds the high-pressure alarm value minus the high-pressure allowable deviation value H (i.e., Pc ≥ high-pressure alarm value - H), the frequency of the compressor will be reduced by a preset unit frequency (e.g., 1Hz) to reduce the system pressure and prevent equipment damage due to excessive pressure. The system will continue to monitor and adjust until the fan AN is successfully restarted or the compressor frequency drops to the minimum safe frequency, ensuring that the fan restarts under safe conditions and avoiding equipment damage caused by frequent restarts.

[0153] Step 4-2: Low pressure situation processing: If the current medium pressure Pc does not exceed the high pressure alarm value minus the high pressure allowable deviation value H (i.e. Pc < high pressure alarm value - H), the system will adjust the output of other fans, and the output of each fan will be reduced by 1 preset unit speed to reduce the burden of the faulty fan AN, and try to restart the fan AN. The system will continue this adjustment and restart process until the faulty fan AN is successfully restarted or the control speed of the remaining fans drops to the minimum safe speed.

[0154] This process ensures that when a fan fails, the system can maintain stable operation by reducing the compressor frequency or adjusting the output of other fans, while avoiding equipment damage caused by excessive pressure. Through this logic, the system can maintain operating efficiency as much as possible while ensuring safety until the faulty fan is repaired or replaced.

[0155] In another possible implementation, before a wind turbine failure occurs, a fault warning strategy can be used, such as a wind turbine fault diagnosis and warning model based on cluster analysis and improved ANFIS, to identify abnormal equipment status in advance and avoid equipment downtime caused by gradual deterioration of health status. For wind turbines with frequent failures, the management of wind farms can optimize the solution by establishing a mathematical model for fault maintenance scheduling.

[0156] This multi-fan matrix control technology mainly solves two key technical problems, thereby significantly improving the operating efficiency and safety of the wind farm. First, it targets the uniformity of the fan speed. By real-time monitoring the current of each fan, the system can accurately determine whether the current speed of each fan is uniform. Once the speed is found to be uneven, the system will automatically adjust the output ratio of the fan to ensure that the speed of all fans remains consistent and achieve uniform distribution of the wind farm. Secondly, when a fault occurs during the operation of the fan, the system will quickly take a series of measures to ensure the safe and stable operation of the system. Specifically, the system will reduce the speed of all fans until the faulty fan can start normally, thereby reducing the burden on the faulty fan and ensuring that other fans will not be damaged due to excessive load. At the same time, if the system detects that the high pressure is too high during the process of reducing the fan speed, the system will further reduce the frequency of the compressor to prevent damage caused by excessive system pressure. In addition, while handling the fault, the system will report the status of the current unit to the management system for further monitoring and maintenance.

[0157] This control technology not only improves the reliability and stability of the system through intelligent monitoring and adjustment, but also improves energy efficiency. Through real-time monitoring and dynamic adjustment, the system can adapt to different operating conditions and ensure optimal performance in all situations, thus providing a strong guarantee for the efficient and stable operation of the wind farm.
