摘要
基于对 TCSC次同步频率等效阻抗特性的研究 ,分析了 TCSC次同步频率等效电阻和等效电抗对抑制次同步谐振 (SSR)的不同作用。发现系统中 SSR的抑制主要取决于 TCSC的次同步频率等效电抗特性 ,而 TCSC的次同步频率等效电阻对 SSR的抑制本质上是一个能量转换过程 ,它只能在一定程度上削弱 SSR,不可能彻底消除 SSR。
Based on the research of equivalent impedance characteristic of TCSC under sub-synchronous frequencies, this paper analyzes the mitigation effect on SSR respectively by TCSC equivalent resistance and TCSC equivalent reactance under sub-synchronous frequencies. It is found that the mitigation of SSR in the system is determined by the sub-synchronous equivalent reactance of TCSC; whereas the mitigation effect on SSR by TCSC equivalent resistance is essentially an energy conversion process, through which SSR can only be mitigated to some extent, rather than completely removed.
