双馈异步风力发电机组定子三相电流不平衡原因分析

Analysis on reasons of unbalance of three-phase currents of double feed asynchronous wind power generator stator

内蒙古华电辉腾锡勒风力发电有限公司#62,#41双馈异步风力发电机组相继发生定子三相电流不平衡故障,对故障原因进行了试验分析,找出了具体的故障位置,可为其他电厂进行双馈异步风力发电机组定子检修时提供参考。

In the double feed asynchronous wind power generators No.62 and No.41 of the Inner Mongolia Huadian Huitengxile Wind Power Generation Company Limited,the unbalance faults of stators three-phase currents had occurred one after another.The reasons of the faults were analyzed and tested;the concrete fault positions were found out.The result of this paper can be used as reference for other wind power farms in stator overhaul of double feed asynchronous wind power generators.
