摘要:
分析双馈异步发电机定子绕组匝间短路故障负序电流的来源,提出以负序电流作为故障特征量进行故障诊断,建立双馈异步发电机仿真模型,通过改变模型中短路匝数和短路电阻的大小实现了匝间短路故障模拟。对仿真发电机在风速恒定的条件下发生定子绕组匝间短路故障进行了模拟。结果表明,定子发生匝间短路故障后,会在定子中增加负序电流分量,定子负序电流的大小随故障严重程度加剧而增加;定子负序电流的大小受发电机负载变化影响很小,有利于轻载状态时定子绕组故障的诊断。
Abstract:
The source of negative sequence current of a doubly-fed induction generator(DFIG)when the DFIG takes place stator winding inter-turn short circuit fault was analyzed in this paper,the negative sequence current as the fault feature of fault diagnosis was put forward,the DFIG simulation model was established,and stator winding inter-turn short circuit fault simulation was achieved by changing the number of turns and the size of short circuit resistance.At last,the simulation of the DFIG was carrie...
