摘　　要：针对双馈感应风力发电机高电压穿越问题,传统的研究只涉及常规双馈感应风力发电机的高电压故障穿越,对于发生定子绕组匝间短路故障的双馈感应风力发电机高电压穿越鲜有研究,且在发生定子绕组匝间短路下的高电压穿越控制策略少有提及。基于此,在分析双馈感应风力发电机暂态特性的基础上建立了含定子绕组匝间短路故障的双馈感应风力发电机数学模型,提出了一种基于无源控制理论的网侧变流器和转子侧变换器控制策略,改善了定子绕组匝间短路的双馈感应风力发电机的故障穿越性能,有助于故障风机高电压穿越的实现。For the high voltage ride through(HVRT)problem of doubly-fed induction wind generator,traditional studies are only concerned with the high voltage fault ride through of conventional doubly-fed induction wind generator,so there is little research on HVRT of doubly-fed induction wind generator with stator winding interturn short circuit(SWITSC)fault,and the control strategy of HVRT in case of SWITSC is rarely mentioned.Based on this and an analysis of the transient characteristics of the doubly-fed induction wind generator,the mathematical model of the doubly-fed induction wind generator with SWITSC fault is established,and a control strategy of network-side converter and rotor-side converter based on passive control theory is proposed,which improves the fault ride through performance of doubly-fed induction wind generator with SWITSC and is helpful to realization of HVRT of faulty fans.
