| 摘 要： | 双馈异步发电机是目前风电行业中的主要机型,如果设计不合理,电机会产生很大的谐波磁场,从而增加电机谐波损耗,劣化发电机效率,降低风能利用率。通过分析双馈异步发电机谐波磁场产生原理,推导出电机谐波磁场的削弱方法,并利用有限元分析对其进行仿真分析,验证了这些削弱措施的正确性。

| Abstract: | At present, doubly-fed induction generator （DFIG） was the main-stream one in the wind power market. The improperly designed DFIG would enlarge the harmonic magnetic field, increase the harmonic loss, reduce the efficiency of the generator and decrease the utility ratio of the wind power. Based on the study of harmonic flux, an effective method of weakening the harmonic flux was presented. The simulation analysis with software FEA demonstrated that the method was effective and correct. |
