摘要
随着现代电力系统向大机组、高电压方向发展,发电机的失步保护日益得到重视。阐述了几种典型的基于阻抗的发电机失步保护方案,并从它们的构成原理上分析其动作特性,从而对现有的几种基于阻抗的发电机失步保护作一比较。
With the advent of EHV system and with the expansion of power transmission system,the relay for gener-ator has been more and more important.This paper describes some traditional out of step relay scheme,which are impedance based.Analysis of the different characteristic of each scheme was also given.
