风电机组偏航交流变频电机的研制

Development of Variable Frequency Yaw Motor for Wind Turbine

为提高风电机组偏航系统的控制精度和响应速度,根据风电机组对偏航系统驱动性能要求,对驱动电机参数进行优化计算,并利用有限元软件进行了仿真分析.在此基础上,设计了一种交流变频偏航驱动电机,对样机进行了试验验证.试验结果显示该变频电机的性能达到了设计要求.

This paper designs an AC variable frequency yaw motor to improve the accuracy and response speed of wind yaw system.According to the requirements of wind yaw system we calculate this moto’s detailed parameters and simulate this model in Maxwell.We also make a test moto to verify our design.The results of experiment prove this model can meet the needs of the wind yaw system.
