发电机次同步谐振抑制策略分析

Analysis of Suppression Strategy of Sub-synchronous Resonance in Power Generators

串联电容补偿引起的电力系统次同步谐波问题是实现远距离经济输电的关键技术问题。以锦忻线和忻石线双回500kV线路为例,具体对抑制次同步谐振(SSR)的策略进行了研究,对次同步谐振抑制装置在运行中存在问题进行了分析,并提出相应措施。

In this paper the effect of series compensation and the causes of sub-synchronous resonance（SSR） are introduced.Based on practical application,the strategy of suppression of SSR is discussed.In addition,the problems of suppression device for SSR in operation are analyzed,and the corresponding measures are put forward.
