摘要
通过对实际多机电力系统的数字仿真研究 ,发现了可控串联补偿 (TCSC)能抑制次同步谐振(SSR)的发生。进一步研究表明 ,TCSC在次同步频率下可能呈现感性 ,从而破坏了产生 SSR的条件。
Through the digital simulation of an actual multi- m achine power system,it is found that the thyristor- controlled series com pensation TCSC can m itigate the sub- synchronous resonance SSR in the system. And the further study shows that under sub- synchronous frequencies the apparent im pedance of TCSC m ay become inductive thus the condition of giving birth to sub- synchronous resonance is destroyed.
