Obviously, the drawings described below are only embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on the provided drawings without creative effort.

[0042] Figure 2 This is a structural block diagram of a device for determining the typhoon resistance performance of a yaw motor, provided in an embodiment of the present invention. Detailed Implementation

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] The conventional yaw motor capability assessment includes drive capability assessment and braking capability assessment. Under typhoon conditions, the control strategies for yaw drive components generally include braking anti-typhoon strategies and active anti-typhoon strategies.

[0045] Currently, Blade simulation cannot simulate yaw start-stop actions. Blade software is a professional wind turbine modeling and load calculation software. The yaw system load is obtained by continuous yaw of the unit. The driving capacity and braking capacity are based on a single continuous load, which can meet the full envelope of the load or short-term non-envelope.

[0046] Currently, the evaluation index for braking and typhoon resistance strategies is the full load envelope or short-term non-envelope. This rough performance evaluation method has a large safety redundancy, which requires the improvement of the load-bearing capacity of the unit's major components, bringing cost pressure.

[0047] The proactive typhoon mitigation strategy requires the yaw motor to operate continuously for 6 hours, but there is no established evaluation metric in the industry. If only the maximum torque envelope of the yaw motor covering the maximum typhoon wind load is used as the evaluation metric, the yaw motor's ability to withstand overload continuously within 6 hours of the typhoon is not considered. If the rated torque envelope of the yaw motor covering the maximum typhoon wind load is used as the evaluation metric, the number of drives in the unit's yaw system needs to be significantly increased.

[0048] Based on the yaw control strategy for typhoon resistance of the unit and the thermal accumulation performance of the yaw motor, this invention proposes a yaw capability evaluation criterion under typhoon resistance conditions. Based on the yaw capability evaluation criterion, a more accurate and scientific typhoon resistance performance of the yaw motor can be obtained.

[0049] The following combination Figure 1 , Figure 1 This is a flowchart of a method for determining the typhoon resistance performance of a yaw motor according to an embodiment of the present invention. The method may include:

[0050] S101: Determine the starting performance of the yaw motor based on its rated torque and starting multiple; determine the maximum equivalent wind load of the system based on the speed ratio of the yaw reducer, the gear ratio between the large and small yaw teeth, and the maximum wind load.

[0051] A yaw drive assembly typically consists of a yaw motor and a yaw reducer. The rated torque of the yaw motor is T. m-rated The starting multiple of the yaw motor is k1. In this embodiment, the starting performance of the yaw motor can be determined based on the rated torque and starting multiple of the yaw motor.

[0052] Specifically, the starting performance T of the yaw motor is determined by multiplying its rated torque and starting multiple. m-rated ×k1, which is the starting torque of the yaw motor.

[0053] In this embodiment, the maximum torque multiple of the yaw motor is k2, so the maximum torque of the yaw motor can be T. m-rated ×k2.

[0054] In this embodiment, the yaw reducer speed ratio is i1, and the gear ratio between the large yaw tooth and the small yaw tooth is i2. This embodiment can convert the measured wind load into the system equivalent wind load with system damping based on the yaw reducer speed ratio and the gear ratio between the large yaw tooth and the small yaw tooth.

[0055] Specifically, this embodiment can determine the maximum wind load T in the active typhoon resistance test. wind-max Dividing the maximum wind load by the gear ratio and then by the yaw reducer ratio yields the maximum system equivalent wind load T, which is converted to system damping. wind-max / i2 / i1.

[0056] S102: Obtain the initial temperature of the yaw motor before the start of typhoon resistance and the termination temperature after the end of typhoon resistance, and determine the temperature rise based on the initial temperature and the termination temperature.

[0057] This embodiment can obtain the initial temperature of the yaw motor before the start of typhoon resistance and the termination temperature after the end of typhoon resistance, and determine the temperature rise based on the initial temperature and the termination temperature.

[0058] This embodiment does not limit the specific method of determining the temperature rise. Generally, the load distribution and single operation time of the yaw motor can be determined. The total number of operations of the yaw motor can be determined based on the typhoon test time and the single operation time. The single braking time of the yaw motor after the end of a single operation can be determined.

[0059] The termination temperature of the yaw motor after a total number of runs is obtained; wherein, the operating conditions of the yaw motor meet the load distribution, running time and braking time of a single run.

[0060] Obtain the initial temperature of the yaw motor before the start of typhoon resistance, and determine the temperature rise based on the initial and final temperatures.

[0061] This embodiment does not limit the specific method for determining the load distribution and single-run time of the yaw motor. Generally, the time-series wind load can be divided into multiple wind load intervals. The system equivalent wind load interval is determined based on the speed ratio and gear ratio of the yaw reducer. The load distribution of the yaw motor in a single run is determined based on the maximum equivalent wind load and interval time within the system equivalent wind load interval. The single-run time of the yaw motor is determined based on the interval time of each system equivalent wind load interval.

[0062] Specifically, the temporal wind load of a typhoon can be divided into n wind load intervals. The system equivalent wind load interval is determined based on the yaw reducer speed ratio and gear ratio. For example, the wind load in the wind load interval is divided by the gear ratio and then divided by the yaw reducer speed ratio to convert the system equivalent wind load.

[0063] In this embodiment, the n equivalent wind load intervals of the system can be (0~T1), (T1~T2), (T2~T3), ..., (T n-1 ~T n ); where the interval time of the equivalent wind load interval of the i-th system is t. i .

[0064] This embodiment can determine the maximum equivalent wind load of the system in each interval, such as T1, T2, ..., T n The load distribution A during a single operation of the yaw motor yaw To ensure the system operates within the corresponding time interval under the maximum equivalent wind load, i.e., the yaw motor's single operation must satisfy A. yaw ={Running time under wind load T1 is t1, running time under wind load T2 is t2, ..., T n The operating time under wind load is t n}

[0065] In this embodiment, the sum of the interval times of all equivalent wind load intervals of the system can be determined as the single running time of the yaw motor. Furthermore, it can be based on the typhoon resistance test time t c and single run time t z Determine the total number of runs m of the yaw motor. ,in For t c / t z The value is rounded up.

[0066] In this embodiment, the termination temperature of the yaw motor after a total number of runs m can be obtained; wherein, the yaw motor needs to meet the single-run load distribution A during each run. yaw The yaw motor's operating time for each run is the single run time t. z The braking time after each operation of the yaw motor is the single braking time t. brake .

[0067] That is, when the yaw motor performs m test runs, [(m×t)] can be used to test the yaw motor. z )+((m-1)×t brake The motor temperature after a certain duration is determined as the termination temperature (Tem) of the yaw motor. py .

[0068] This embodiment can be based on the initial temperature Tem of the yaw motor before the start of typhoon response. p0 and the termination temperature Tem after the typhoon ends py Determine the temperature rise Tem p =Tem py -Tem p0 .

[0069] This embodiment does not limit the specific method for determining the single braking time. Generally, historical typhoon resistance operation data of the wind turbine can be obtained, and the historical single braking time of the yaw motor can be determined from the historical typhoon resistance operation data. Based on the historical single braking time, the single braking time of the yaw motor after the end of a single operation can be determined.

[0070] Because different wind turbine units operate in diverse environments, and the braking time of the yaw motor varies under different environments, this embodiment can obtain the environmental characteristics of the target wind turbine unit, and match similar wind turbine units based on these characteristics; the median of the historical single braking time of similar wind turbine units is determined as the single braking time of the yaw motor after a single operation.

[0071] This embodiment does not limit the method of determining the typhoon resistance test time. It can generally be determined based on the historical typhoon conditions of the target area where the target wind turbine is located. In this embodiment, it can be set to 6 hours.

[0072] S103: When the starting performance of the yaw motor is greater than the maximum system equivalent wind load and the temperature rise is less than the motor insulation temperature, the yaw motor is determined to meet the active typhoon resistance performance.

[0073] In this embodiment, when evaluating the performance of the yaw motor under the active typhoon resistance strategy, two indicators can be set. That is, the starting performance of the yaw motor needs to be greater than the maximum system equivalent wind load, and the temperature rise needs to be less than the motor insulation temperature.

[0074] When a yaw motor starts, its active power is relatively small, with reactive power being the majority; that is, most electrical energy is converted into heat. If the yaw motor stalls, its electrical energy is directly converted into heat, causing a rapid increase in temperature. Therefore, the starting capacity design of the yaw motor must consider the maximum wind load of the typhoon-resistant unit, i.e., T. m-rated ×k1>T wind-max / i2 / i1, or T m-rated ×k1≥T wind-max / i2 / i1.

[0075] Yaw motors utilize thermal accumulation performance and short-term overload capacity to withstand continuous typhoons; therefore, the temperature rise during typhoon resistance must be considered in the motor design. Tem p The temperature must not exceed the motor insulation temperature Tem j , that is Tem p <Tem j ,or Tem p ≤Tem j Otherwise, the motor design needs to be adjusted.

[0076] If the starting performance of the yaw motor is greater than the maximum system equivalent wind load and the temperature rise is less than the motor insulation temperature, then the yaw motor is determined to meet the active typhoon resistance performance.

[0077] S104: When the braking performance of the yaw motor is greater than the maximum system equivalent wind load, the yaw motor is determined to meet the braking anti-typhoon performance.

[0078] In this embodiment, if the braking performance of the yaw motor is greater than the maximum system equivalent wind load, then the yaw motor is determined to meet the braking anti-typhoon performance.

[0079] This embodiment can determine the braking force M of the yaw motor. motor-brake Braking performance is determined based on braking force, yaw reducer ratio, and gear ratio; specifically, the product of braking force, yaw reducer ratio, and gear ratio can be used to determine the braking performance M. motor-brake ×i1×i2.

[0080] Braking performance based on yaw motor M motor-brake ×i1×i2 and caliper braking performance M brake To determine braking performance.

[0081] When the braking performance is greater than the maximum system equivalent wind load M under the braking and typhoon resistance strategy wind-max When this condition is met, the yaw motor is determined to meet the braking anti-tying performance, that is, when (M motor-brake ×i1×i2)+M brake >M wind-max At that time, or (M) motor-brake ×i1×i2)+M brake ≥M wind-max At that time, it was determined that the yaw motor met the braking anti-typhoon performance.

[0082] This embodiment can set performance evaluation indicators for the yaw motor under active typhoon resistance strategy and braking typhoon resistance strategy respectively. By using the performance evaluation indicators, it can be determined whether the yaw motor meets the active typhoon resistance performance and braking typhoon resistance performance, which can effectively guide the quantity and performance design of the yaw motor and the corresponding yaw system.
