兆瓦级双馈风力发电机定子温度场有限元计算

摘要

The paper presented the basic structure of MW-class double-fed wind generator. The FEM model of generator stator was established and the calculation methods of heat parameters were given. At the same time,the stator temperature field was calculated by the software of Ansys. Analysis and compare of the testing and calculation results demonstrate that the models and simulation methods are correct and reliable.%文章在论述兆瓦级双馈风力发电机基本结构的基础上,利用有限元法建立了发电机定子有限元计算模型,给出了相应的热性能参数计算方法；应用有限元分析软件Ansys对发电机的定子温度场进行了仿真计算,通过试验与仿真结果的对比分析,表明了有限元模型和仿真方法的正确性和可行性.
