Description

Technical Field

[0001] The present application relates to the field of financial technology, and in particular to a wind turbine energy storage method, device, equipment and storage medium. Background Art

[0002] With the rapid development of information technology, the scale of data centers and the number of server equipment in banks and other financial institutions are growing at an unprecedented rate, leading to a significant increase in power consumption and cooling requirements. Server equipment within data center computer rooms must maintain a constant temperature, necessitating a continuously operating air conditioning and cooling system to effectively dissipate the heat generated by the server equipment. Currently, cooling systems such as air-cooled direct expansion air conditioners, water-cooled computer room air conditioners, water-cooled / air-cooled chilled water systems, and liquid cooling systems are commonly used to dissipate the heat generated by the server equipment.

[0003] Taking an air-cooled direct expansion air conditioner as an example, the outdoor unit of the air-cooled direct expansion air conditioner generally contains one or more fans; if the temperature in the data center room is higher than 28 degrees, the control system will start the outdoor unit, and then the fan will start to rotate to discharge the heat in the data center room; if the temperature in the data center room is lower than 20 degrees, the compressor in the outdoor unit will be controlled to stop running, and then the fan will also gradually stop rotating.

[0004] In actual work, since the temperature in the data center room is constantly changing, the compressor in the outdoor unit is constantly switching between start and stop states, which causes the fan to start and stop frequently; after the compressor stops running, the fan will not stop immediately, but the speed will gradually decrease, that is, it will enter the idling state. After the fan enters the idling state, the kinetic energy generated by its rotation will be wasted. Summary of the Invention

[0005] In order to fully utilize the kinetic energy generated when the wind turbine enters the idling state, the present application provides a wind turbine energy storage method, device, equipment and storage medium.

[0006] In a first aspect, the present application provides a wind turbine energy storage method, comprising:

[0007] In response to the compressor stopping, monitoring the fan speed to obtain an initial idling speed and a current idling speed;

[0008] Based on the initial idling speed and the current idling speed, switching the working mode of the bidirectional working motor in the wind turbine to a power generation mode;

[0009] Switch the power supply's operating mode to energy storage mode.

[0010] Through the above implementation, after the compressor stops running, by monitoring the initial idling speed and the current idling speed, it can be determined whether the fan is in an idling state, thereby determining whether the working mode of the bidirectional working motor can be switched to the power generation mode. If so, after switching to the power generation mode, the working mode of the power supply is also switched to the energy storage mode. In this way, the fan drives the bidirectional working motor in the power generation mode to generate electrical energy in the idling state and stores it in the power supply; this makes it easy to fully utilize the kinetic energy generated when the fan enters the idling state.

[0011] Preferably, switching the working mode of the bidirectional working motor in the wind turbine to the power generation mode based on the initial idling speed and the current idling speed includes:

[0012] Calculating falling speed information based on the initial idling speed and the current idling speed;

[0013] In response to the speed drop information satisfying a preset mode switching condition, the working mode of the bidirectional working motor in the wind turbine is switched to a power generation mode.

[0014] Through the above implementation, the falling speed information is further calculated by monitoring the initial idling speed and the current idling speed, so that it is convenient to judge whether the working mode of the bidirectional working motor can be switched to the power generation mode based on the falling speed information and the preset mode switching conditions. That is, the timing of switching the working mode of the bidirectional working motor to the power generation mode can be determined by monitoring the initial idling speed and the current idling speed.

[0015] Preferably, the calculating the falling speed information based on the initial idling speed and the current idling speed includes:

[0016] Calculating the difference between the initial idling speed and the current idling speed to obtain a speed drop;

[0017] Determine the deceleration corresponding to the current idling speed to obtain the falling speed deceleration;

[0018] Based on the speed drop amount and the speed drop deceleration, speed drop information is obtained.

[0019] Through the above implementation, the difference between the initial idling speed and the current idling speed is used as the falling speed deceleration, and the deceleration corresponding to the current idling speed is used as the falling speed deceleration. This makes it convenient to use the falling speed deceleration and the falling speed deceleration as the specific information content of the falling speed information, so as to facilitate the subsequent determination of the timing for the bidirectional working motor to switch the working mode to the power generation mode based on the falling speed deceleration and the falling speed deceleration.

[0020] Preferably, in response to the speed drop information satisfying a preset mode switching condition, switching the working mode of the bidirectional working motor in the wind turbine to the power generation mode includes:

[0021] In response to the speed drop being greater than a preset drop threshold and the speed drop deceleration being greater than a preset deceleration threshold, the working mode of the bidirectional working motor in the wind turbine is switched to a power generation mode.

[0022] Through the above implementation, the speed drop in the speed drop information and the speed drop deceleration are compared with the corresponding thresholds respectively to determine whether the working mode of the bidirectional working motor is switched to the power generation mode; through double comparison judgment, the timing of switching the working mode of the bidirectional working motor to the power generation mode is determined, which facilitates improving the accuracy of determining the timing of switching the working mode.

[0023] Preferably, after switching the working mode of the power supply to the energy storage mode, the method further includes:

[0024] In response to the current idling speed being less than a preset minimum speed threshold, the power generation mode of the bidirectional working motor and the energy storage mode of the power supply are terminated.

[0025] Through the above implementation, when the current idling speed is low, the energy storage work of the bidirectional working motor and the power supply is stopped. This makes it easy to stop the bidirectional working motor and the power supply from continuing to store electrical energy when the energy storage efficiency is very low, and prepare for the subsequent power supply to the fan and compressor.

[0026] Preferably, after terminating the power generation mode of the bidirectional motor and the energy storage mode of the power supply, the method further includes:

[0027] detecting the current power level of the power supply;

[0028] In response to the current power being greater than a power threshold and receiving a start-up signal for the compressor, supplying power to the compressor and the fan using the power supply;

[0029] In response to the current power level being not greater than the power threshold, the compressor and the fan are supplied with power from the mains.

[0030] Through the above implementation, when the power supply is sufficient, the power supply is used to power the compressor and the fan; when the power supply is insufficient, the AC power is used to power the compressor and the fan; this facilitates the application of the electric energy collected by the idling of the fan to the power supply of the compressor and the fan, thereby facilitating the improvement of the utilization efficiency of electric energy.

[0031] In a second aspect, the present application provides a wind turbine energy storage device, comprising:

[0032] A speed monitoring module is used to monitor the fan speed in response to the compressor stopping operation, and obtain the initial idling speed and the current idling speed;

[0033] a mode switching module, configured to switch the working mode of the bidirectional working motor in the wind turbine to a power generation mode based on the initial idling speed and the current idling speed;

[0034] The energy storage module is used to switch the working mode of the power supply to the energy storage mode.

[0035] Through the above implementation, after the compressor stops running, by monitoring the initial idling speed and the current idling speed, it can be determined whether the fan is in an idling state, thereby determining whether the working mode of the bidirectional working motor can be switched to the power generation mode. If so, after switching to the power generation mode, the working mode of the power supply is also switched to the energy storage mode. In this way, the fan drives the bidirectional working motor in the power generation mode to generate electrical energy in the idling state and stores it in the power supply; this makes it easy to fully utilize the kinetic energy generated when the fan enters the idling state.

[0036] In a third aspect, the present application provides a computer device, which includes a memory and a processor, wherein the memory stores a computer program, and the processor implements the steps in the above method when executing the computer program.

[0037] In a fourth aspect, the present application provides a computer-readable storage medium having a computer program stored thereon, which implements the steps in the above-mentioned method when executed by a processor.

[0038] In a fifth aspect, the present application further provides a computer program product, which includes a computer program that implements the steps of any of the above method embodiments when executed by a processor.

[0039] The above-mentioned fan energy storage method, device, equipment and storage medium monitor the fan speed in response to the compressor stopping operation to obtain the initial idling speed and the current idling speed; based on the initial idling speed and the current idling speed, the working mode of the bidirectional working motor in the fan is switched to the power generation mode; and the working mode of the power supply is switched to the energy storage mode. Through the above implementation, after the compressor stops running, it can be determined whether the fan is in an idling state by monitoring the initial idling speed and the current idling speed, and thus it can be determined whether the working mode of the bidirectional working motor can be switched to the power generation mode. If so, after switching to the power generation mode, the working mode of the power supply is also switched to the energy storage mode. In this way, the fan drives the bidirectional working motor in the power generation mode to store the electrical energy generated in the power supply in the idling state; this facilitates the full utilization of the kinetic energy generated when the fan enters the idling state.

It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not intended to limit the present disclosure.

Furthermore, the character " / " in this document generally indicates an "or" relationship between the related objects.

[0049] Example 1

[0050] Figure 1 A flow chart of a wind turbine energy storage method provided in Example 1 of this application, refer to Figure 1 The method may be performed by a device for performing the method, and the device may be implemented by software and / or hardware. The method includes:

[0051] S110 : In response to the compressor stopping, monitoring the fan speed to obtain an initial idling speed and a current idling speed.

[0052] Among them, banks and other financial institutions have data centers for the storage and management of financial data. There are multiple servers in the data center computer room, and the servers are specifically used for the storage and management of financial data. The servers will generate a lot of heat in the data center computer room during operation, so that the temperature of the server itself and the data center computer room will continue to rise. Excessive temperature will seriously affect the data processing performance of the server. For this reason, the data center computer room is generally equipped with a cooling air conditioner. The outdoor unit of the cooling air conditioner is provided with a compressor. The compressor is used to increase the pressure and temperature of the refrigerant (such as R410A, R32) by compressing it to promote the refrigeration cycle. The air-conditioning control system is provided with a thermometer in the data center computer room. The thermometer is used to detect the temperature in the data center computer room and transmit the temperature back to the air-conditioning control system. If the air-conditioning control system determines that the temperature is lower than the preset temperature threshold, it will control the compressor in the outdoor unit to stop running. For example, the above temperature threshold is 20 degrees Celsius.

[0053] In addition to the compressor, the outdoor unit is also equipped with a condenser and a fan. The condenser is used to cool and liquefy the high-temperature and high-pressure refrigerant gas discharged from the compressor, releasing heat to the outside; the fan is used to accelerate air flow and assist the condenser in heat dissipation; if the compressor is controlled to stop running, the fan will enter an idling state. The so-called idling state means that the fan blades continue to rotate due to inertia, but the speed gradually decreases.

[0054] After the air conditioning control system controls the compressor to stop running, it immediately monitors the rotation speed of the fan blades to obtain the fan speed, and records the fan speed monitored at the beginning of monitoring as the initial idling speed v0, and also records the fan speed monitored at the current moment as the current idling speed v n The air conditioning control system monitors the fan speed through a speed sensor installed on the fan, with a monitoring frequency of 10 times / s.

[0055] S120: Based on the initial idling speed and the current idling speed, switch the working mode of the bidirectional working motor in the wind turbine to a power generation mode.

[0056] After the compressor stops, the fan needs to continue accelerating air flow and assisting in cooling the condenser for a while. Only when the fan speed drops to a certain level can the kinetic energy generated by the fan idling be converted into electrical energy for storage. To this end, the initial idling speed can be compared with the current idling speed to determine whether the fan speed has dropped to a certain level.

[0057] In this embodiment, the fan consists of a bidirectional working motor and fan blades installed on the bidirectional working motor. The bidirectional working motor can drive the fan blades to rotate, that is, convert electrical energy into kinetic energy. On the other hand, when the fan blades are idling, the current working mode can be converted into a power generation mode by switching the corresponding circuit. At this time, when the fan blades are idling, they can drive the bidirectional working motor to convert kinetic energy into electrical energy.

[0058] Specifically, the air-conditioning control system determines whether the fan speed has dropped to a certain level by comparing the initial idling speed with the current idling speed; if it is determined that the fan speed has dropped to a certain level, indicating that the kinetic energy generated by the fan idling is actually converted into electrical energy, the air-conditioning control system further controls the bidirectional working motor to convert the working mode into the power generation mode, converting the kinetic energy of the fan rotation into mechanical energy, and the mechanical energy is converted into electrical energy through the magnetic field interaction between the stator and rotor in the motor.

[0059] S130: Switch the working mode of the power supply to the energy storage mode.

[0060] The bidirectional working motor is connected to a power source via a wire, and the power source is used to receive the electric energy converted by the bidirectional working motor or to transmit stored electric energy to the bidirectional working motor.

[0061] It should be noted that when the air-conditioning control system converts the working mode of the bidirectional working motor to the power generation mode so that the bidirectional working motor can convert electrical energy, it will also switch the working mode of the power supply to the energy storage mode so that the power supply can receive and store the electrical energy converted by the bidirectional working motor.

[0062] It should be noted that, in this embodiment, after the compressor stops running, by monitoring the initial idling speed and the current idling speed, it can be determined whether the fan is in an idling state, thereby determining whether the working mode of the bidirectional working motor can be switched to the power generation mode. If so, after switching to the power generation mode, the working mode of the power supply is also switched to the energy storage mode. In this way, the fan drives the bidirectional working motor in the power generation mode to generate electrical energy in the idling state and stores it in the power supply; this makes it easy to fully utilize the kinetic energy generated when the fan enters the idling state.

[0063] Example 2

[0064] A wind turbine energy storage method is provided in a second embodiment of the present application. This method optimizes the method of "switching the operating mode of the bidirectional working motor in the wind turbine to the power generation mode based on the initial idling speed and the current idling speed" in the first embodiment. It should be noted that for portions not described in detail in this embodiment, reference may be made to the descriptions of other embodiments. The method includes:

[0065] S210 : In response to the compressor stopping, monitoring the fan speed to obtain an initial idling speed and a current idling speed.

[0066] S221: Calculate falling speed information based on the initial idling speed and the current idling speed.

[0067] The falling speed information is based on the initial idling speed v0 and the current idling speed v n The calculated data volume, the speed drop information is used to represent the degree of decrease in the current fan speed.

[0068] S222: In response to the speed drop information satisfying a preset mode switching condition, the working mode of the bidirectional working motor in the wind turbine is switched to a power generation mode.

[0069] Among them, the mode switching condition is a judgment condition set for the above-mentioned speed drop information. If the speed drop information meets the mode switching condition, it means that the fan speed has dropped to a certain level, which is suitable for converting the fan's kinetic energy into electrical energy. This is the moment to switch the working mode of the bidirectional working motor in the fan to the power generation mode.

[0070] It should be noted that the falling speed information is further calculated by monitoring the initial idling speed and the current idling speed, so that it is convenient to judge whether the working mode of the bidirectional working motor can be switched to the power generation mode based on the falling speed information and the preset mode switching conditions. That is, the timing of switching the working mode of the bidirectional working motor to the power generation mode can be determined by monitoring the initial idling speed and the current idling speed.

[0071] S230: Switch the working mode of the power supply to the energy storage mode.

[0072] Example 3

[0073] A wind turbine energy storage method is provided in a third embodiment of the present application. This method optimizes the "calculating the falling speed information based on the initial idling speed and the current idling speed" in the second embodiment. It should be noted that for parts not described in detail in this embodiment, reference may be made to the descriptions of other embodiments. This method includes:

[0074] S310 : In response to the compressor stopping, monitoring the fan speed to obtain an initial idling speed and a current idling speed.

[0075] S321A: Calculate the difference between the initial idling speed and the current idling speed to obtain a speed drop.

[0076] The speed drop is the difference between the initial idling speed v0 and the current idling speed v n The speed drop is recorded as v △ , v △ =v0-v n ; Speed ​​drop v △ Used to represent the current idling speed v n The decrease compared to the initial idling speed v0.

[0077] S321B: Determine the deceleration corresponding to the current idling speed to obtain the falling speed deceleration.

[0078] Each fan speed has a corresponding collection time, and the collection time corresponding to the current idling speed v0 is recorded as the current collection time t0, and the collection time before the current collection time t0 is recorded as the previous collection time t -1 , the previous acquisition time t -1 The corresponding fan speed is recorded as the previous idling speed v -1 After determining the current idling speed v0 corresponding to the current acquisition time t0, the previous acquisition time t -1 The corresponding previous idling speed v -1 , and according to the current acquisition time t0, the current idling speed v0, the previous acquisition time t -1 and the previous idling speed v -1 Calculate the deceleration corresponding to the current acquisition time t0, and record the deceleration as the falling deceleration a0. The calculation formula of the falling deceleration a0 is:

[0079] a0=(v0-v -1 ) / (t0-t -1 );

[0080] The speed reduction rate a0 is used to represent the speed at which the fan speed decreases at the current acquisition moment.

[0081] S321C: Obtain speed drop information based on the speed drop amount and the speed drop deceleration.

[0082] In this embodiment, the speed drop information includes two data quantities: speed drop v △ And the falling speed deceleration a0.

[0083] It should be noted that the difference between the initial idling speed and the current idling speed is used as the falling speed deceleration, and the deceleration corresponding to the current idling speed is used as the falling speed deceleration. This makes it convenient to use the falling speed deceleration and the falling speed deceleration as the specific information content of the falling speed information, so as to facilitate the subsequent determination of the timing for the bidirectional working motor to switch the working mode to the power generation mode based on the falling speed deceleration and the falling speed deceleration.

[0084] S322: In response to the speed drop information satisfying a preset mode switching condition, the working mode of the bidirectional working motor in the wind turbine is switched to a power generation mode.

[0085] S330: Switch the working mode of the power supply to the energy storage mode.

[0086] Example 4

[0087] A wind turbine energy storage method is provided in a fourth embodiment of the present application. This method optimizes the method of "switching the operating mode of the bidirectional working motor in the wind turbine to the power generation mode in response to the speed drop information satisfying a preset mode switching condition" in the third embodiment. It should be noted that for portions not described in detail in this embodiment, reference may be made to the descriptions of other embodiments. The method includes:

[0088] S410 : In response to the compressor stopping, monitoring the fan speed to obtain an initial idling speed and a current idling speed.

[0089] S421A: Calculate the difference between the initial idling speed and the current idling speed to obtain a speed drop.

[0090] S421B: Determine the deceleration corresponding to the current idling speed to obtain the falling speed deceleration.

[0091] S421C: Obtain speed drop information based on the speed drop amount and the speed drop deceleration.

[0092] S422: In response to the speed drop being greater than a preset drop threshold and the speed drop deceleration being greater than a preset deceleration threshold, switching the working mode of the bidirectional working motor in the wind turbine to a power generation mode.

[0093] In order to determine whether the falling speed information corresponding to the current acquisition time t0 meets the preset mode switching condition, this embodiment focuses on the speed drop v in the falling speed information. △ A drop threshold is set, and a deceleration threshold is set for the drop deceleration a0 in the drop speed information; if the speed drop v △ If the value is greater than the drop threshold and the drop deceleration a0 is greater than the deceleration threshold, it indicates whether the drop speed information meets the preset mode switching condition, that is, it is suitable to switch the working mode of the bidirectional working motor in the wind turbine to the power generation mode.

[0094] It should be noted that the speed drop in the speed drop information and the speed drop deceleration are compared with the corresponding thresholds respectively to determine whether the working mode of the bidirectional working motor is switched to the power generation mode; through double comparison judgment, the timing of switching the working mode of the bidirectional working motor to the power generation mode is determined, which facilitates improving the accuracy of determining the timing of switching the working mode.

[0095] S430: Switch the working mode of the power supply to the energy storage mode.

[0096] Example 5

[0097] A wind turbine energy storage method is provided in Example 5 of the present application. This method supplements the method described in Example 1. It should be noted that for parts not described in detail in this embodiment, reference may be made to the descriptions in other embodiments. The method includes:

[0098] S510 : In response to the compressor stopping, monitoring the fan speed to obtain an initial idling speed and a current idling speed.

[0099] S520: Based on the initial idling speed and the current idling speed, switch the working mode of the bidirectional working motor in the wind turbine to a power generation mode.

[0100] S530: Switch the working mode of the power supply to the energy storage mode.

[0101] S540: In response to the current idling speed being less than a preset minimum speed threshold, the power generation mode of the bidirectional working motor and the energy storage mode of the power supply are terminated.

[0102] It should be noted that after the working mode of the bidirectional working motor is switched to the power generation mode and the working mode of the power supply is switched to the energy storage mode, the bidirectional working motor first converts the kinetic energy of the fan blades into mechanical energy, further converts the mechanical energy into electrical energy, and transmits the electrical energy to the power supply in the energy storage mode for storage, thereby realizing fan energy storage. As the energy storage process continues to advance, the kinetic energy of the fan blades gradually decreases, that is, the speed of the fan continues to decrease. In a short period of time before the fan speed is 0, the kinetic energy of the fan blades is already very low. At this time, it is basically impossible to effectively transmit electrical energy to the power supply, but the fan blades will still rotate very slowly. When the kinetic energy of the fan blades is already very low, but the fan speed is not yet 0, it is suitable to end the energy storage process so that the bidirectional working motor and the power supply can be prepared for the working state when the compressor is started next time.

[0103] Specifically, in order to determine whether the kinetic energy of the fan blades is already very low, the air-conditioning control system sets a minimum speed threshold for the current idling speed v0. The minimum speed threshold is used to compare with the current idling speed v0. If the current idling speed v0 is less than the minimum speed threshold, it means that the bidirectional working motor can basically no longer effectively transmit electrical energy to the power supply. The air-conditioning control system then ends the power generation mode of the bidirectional working motor and the energy storage mode of the power supply, that is, ends the energy storage process.

[0104] It should be noted that when the current idling speed is low, the energy storage work of the bidirectional working motor and the power supply is stopped. This makes it easy to stop the bidirectional working motor and the power supply from continuing to store electrical energy when the energy storage efficiency is very low, and prepare for the subsequent power supply to the fan and compressor.

[0105] Example 6

[0106] A wind turbine energy storage method is provided in Example 6 of the present application. This method supplements the method described in Example 5. It should be noted that for parts not described in detail in this embodiment, reference may be made to the descriptions in other embodiments. This method includes:

[0107] S610: In response to the compressor stopping, monitor the fan speed to obtain an initial idling speed and a current idling speed.

[0108] S620: Based on the initial idling speed and the current idling speed, switch the working mode of the bidirectional working motor in the wind turbine to a power generation mode.

[0109] S630: Switch the working mode of the power supply to the energy storage mode.

[0110] S640: In response to the current idling speed being less than a preset minimum speed threshold, the power generation mode of the bidirectional working motor and the energy storage mode of the power supply are terminated.

[0111] S650: Detect the current power level of the power supply.

[0112] Among them, the compressor and fan in the air-conditioning outdoor unit are originally powered by the mains electricity. In this embodiment, after multiple power transmissions to the power supply, the power supply will store a certain amount of electricity, which can also be used to power the compressor and fan in the air-conditioning outdoor unit for a period of time to save electricity. In order to determine whether a certain amount of electricity is currently stored in the power supply, it is necessary to detect the electricity of the power supply at the current moment to obtain the current electricity of the power supply.

[0113] S660: In response to the current power being greater than the power threshold and receiving a start-up signal for the compressor, supply power to the compressor and the fan using the power supply.

[0114] Among them, in order to determine whether the amount of electricity currently stored in the power supply can be used to power the compressor and the fan, this embodiment sets a power threshold for the current amount of electricity. If the current amount of electricity is greater than the power threshold, it means that the amount of electricity stored in the power supply can be used to power the compressor and the fan; if the air-conditioning control system receives a start-up signal for the compressor at this time, it means that the compressor is about to start working, and the power supply is controlled to supply power to the compressor and the fan.

[0115] S670: In response to the current power level being not greater than the power threshold, supplying power to the compressor and the fan using AC power.

[0116] If it is determined that the current power level is not greater than the power threshold, it means that the power stored in the power supply cannot be used to power the compressor and the fan. At this time, the mains power is still used to power the compressor and the fan.

[0117] It should be noted that when the power supply is sufficient, the power supply is used to supply power to the compressor and the fan. When the power supply is insufficient, the AC power is used to supply power to the compressor and the fan. This facilitates the application of the electric energy collected by the idling of the fan to the power supply of the compressor and the fan, thereby facilitating the improvement of the utilization efficiency of electric energy.

[0123] a mode switching module, configured to switch the working mode of the bidirectional working motor in the wind turbine to a power generation mode based on the initial idling speed and the current idling speed;

[0124] The energy storage module is used to switch the working mode of the power supply to the energy storage mode.

[0125] Each module in the aforementioned wind turbine energy storage device can be implemented in whole or in part through software, hardware, or a combination thereof. Each module can be embedded in or independent of a processor in a computer device in hardware form, or stored in a computer device memory in software form, so that the processor can call and execute the corresponding operations of each module.

[0126] It should be noted that, in this embodiment, after the compressor stops running, by monitoring the initial idling speed and the current idling speed, it can be determined whether the fan is in an idling state, thereby determining whether the working mode of the bidirectional working motor can be switched to the power generation mode. If so, after switching to the power generation mode, the working mode of the power supply is also switched to the energy storage mode. In this way, the fan drives the bidirectional working motor in the power generation mode to generate electrical energy in the idling state and stores it in the power supply; this makes it easy to fully utilize the kinetic energy generated when the fan enters the idling state.

[0127] In an optional embodiment, in terms of switching the working mode of the bidirectional working motor in the wind turbine to the power generation mode based on the initial idling speed and the current idling speed, the mode switching module is specifically configured to:

[0128] Calculating falling speed information based on the initial idling speed and the current idling speed;

[0129] In response to the speed drop information satisfying a preset mode switching condition, the working mode of the bidirectional working motor in the wind turbine is switched to a power generation mode.

[0130] In an optional embodiment, in calculating the falling speed information based on the initial idling speed and the current idling speed, the mode switching module is specifically configured to:

[0131] Calculating the difference between the initial idling speed and the current idling speed to obtain a speed drop;

[0132] Determine the deceleration corresponding to the current idling speed to obtain the falling speed deceleration;

[0133] Based on the speed drop amount and the speed drop deceleration, speed drop information is obtained.

[0134] In an optional embodiment, in response to the speed drop information satisfying a preset mode switching condition, the mode switching module switches the working mode of the bidirectional working motor in the wind turbine to the power generation mode, and is specifically configured to:

[0135] In response to the speed drop being greater than a preset drop threshold and the speed drop deceleration being greater than a preset deceleration threshold, the working mode of the bidirectional working motor in the wind turbine is switched to a power generation mode.

[0136] In an optional embodiment, after the operating mode of the power supply is switched to the energy storage mode, the wind turbine energy storage device further includes:

[0137] The mode termination module is used to terminate the power generation mode of the bidirectional working motor and the energy storage mode of the power supply in response to the current idling speed being less than a preset minimum speed threshold.

[0138] In an optional embodiment, after the power generation mode of the bidirectional working motor and the energy storage mode of the power supply are terminated, the wind turbine energy storage device further includes:

[0139] A power detection module, used to detect the current power of the power supply;

[0140] a power supply module, configured to supply power to the compressor and the fan using the power supply in response to the current power being greater than a power threshold and receiving a start-up signal for the compressor;

[0141] The mains power supply module is configured to supply power to the compressor and the fan using the mains power in response to the current power being no greater than a power threshold.
