并联电抗器降低输电线路静态稳定性的机理分析

Mechanism Study of Reducing Static Stability about Transmission Line with Shunt Reactor

针对在电力系统中越来越多地使用并联电抗器的情况,为正确认识并联电抗器的作用,采用基于波过程和二端口网络理论相结合的方法,对并联电抗器降低输电线路静态稳定性的机理进行了研究,通过改变并联电抗器的某些重要参数,分析输电线路静态稳定功率极限的变化情况,得出了一些重要结果。

Due to more and more shunt reactors used in power system, it is necessary to correct understanding the effect of the shunt reactors on power systems. This paper uses the wave process and two-port networks theories to study the mechanism of reducing static stability about transmission line with shunt reactors. By changing the key parameters of the shunt reactors, it analyzes the mechanism of the static transmission power limiting. Then it obtains some important results.
