GE公司EX2100励磁调节器V/Hz限制动作原因分析

Cause Analysis of V/Hz Limiter Action for GE EX2100 Excitation Regulators

详细分析了GE公司EX2100励磁调节器V/Hz限制动作原理,找到了国内某电厂发电机励磁系统频繁误报过激磁限制的原因,确定了GE公司EX2100励磁调节器在设计方面的缺陷,并提出了相应的改进策略。

Based on detailed analysis of the operating principle of V/Hz limiter for GE EX2100 excitation regulator, the reason of frequently misstated excitation restriction occurring in the generator excitation system of a domestic power plant was found to be caused by design deficiency in the GE EX2100 excitation regulator, for which corresponding improvement measures were suggested.
