摘要:
针对大型永磁风力发电机设计及运行安全性问题,以1.5MW永磁半直驱式同步风力发电机为研究对象,设计三种极槽比不同的发电机方案,建立风力发电机电磁场二维有限元计算模型,并确定出每种方案的绕组设计参数。研究永磁半直驱式同步风力发电机负载工况下的电磁场分布;计算气隙内谐波含量的大小;同时,根据传热学理论,建立温度场二维有限元计算模型,给出了转子旋转时气隙内空气的有效导热系数及三种结构方案发电机温度分布计算结果。最后,对相同类型结构的小型永磁同步风力发电机的实测数据与理论计算结果进行比较以验证计算方法的正确性。通过以上的研究工作可以使相应的研究更加深入,通过提高电机内温度场的计算精确度可以有效地降低大型风力发电机故障率,为大容量永磁半直驱风力发电机的设计提供一些有意义的参考。
Abstract:
Aiming at running security and design of large capacity of permanent magnent wind generator,a 1.5MW half-direct permanent magnet synchronous wind generator was investigated,for which three structures with different slot/pole ratio were designed,and the 2D finite element analysis models for the electromagnetic fields of generators were established,and the parameters of armature windings are also determined.The electromagnetic fields of machine operation at rated load were studied,and then the flux density ha...
