摘要：

随着大容量远距离输电的发展,串联电容补偿技术在超高压、远距离输电中得到了广泛应用。文中介绍了串联电容补偿装置的构成、工作原理,以及等效模型的不同工作方式,分析了MOV的工作特性。串联电容补偿技术是一项成熟的技术,通过串联电容补偿线路感抗,缩短交流传输的电气距离,降低线路输送损耗,改善线路的电压质量,提高线路传输功率,更加合理地分布输送功率,提高系统的动态稳定和静态稳定性。

Abstract:

With the development of large capacity and long distance power transmission,series capacitor compensation techniques have been widely applied in ultra high voltage long-distance transmission.This paper introduces the composition and working principle of series capacitor compensation device,and the equivalent model of the different ways of working.The characteristics of MOV are analyzed.Series capacitor compensation technology is a mature technology,by which the series capacitor compensation circuit inductance shortens electrical distance AC transmission,reduces line loss,and improves the line voltage quality and the transmission power with more reasonable distribution of transmission power,system dynamic stability and static stability.

Key words: series compensation capacitor;series compensated transmission line;distance protection;line impedance
