摘要
为判断永磁风力发电机定子绕组及永磁体运行时的稳定性,准确计算电机内的温度场非常重要,以一台100kW,100r/min的径向磁通永磁同步风力发电机为例,采用三维有限元法对发电机的温度场进行计算,并分析在计算中某些关键因素对温度场计算结果的影响。通过对计算结果与实验数据的比较分析,验证了计算方法的正确性;得出了一些有意义的结论,可为永磁同步风力发电机的设计提供参考。
In order to estimate operating stability of wind generator stator winding and permanent magnet in operation, it is necessary to calculate the thermal field of gengertor. A 100kW, 100r/min radial flux permanent magnet synchronous wind generator was investigated, firstly using finite element method to calculate the temperature field. Some key factors that may have a great influence on thermal analysis are considered. At last, the comparisons of the analysis results with test data were proposed to verify the correctness of calculation. Conclusions can be drawn to provide certain references for designing the permanent magnet synchronous wind generator.
