伊冯可控串补过电压保护控制及主动绝缘配合研究

OVERVOLTAGE PROTECTION CONTROL AND ACTIVE INSULATIONCOORDINATION OF YI FENG THYRISTOR CONTROLLED SERIES COMPENSATION

文章介绍东北伊冯５００ｋＶ可控串补装置的过电压保护控制策略及主动绝缘配合的设想和措施。提出了采用主动绝缘配合方法后，伊冯可控串补的过电压保护水平、氧化锌限压器的容量、晶闸管电流等主要技术参数及其概率分布。

This paper discusses the overvoltage protection control strategy and methodology of active insulation coordination for Yi Feng thyristor controlled series compensation. The overvoltage protection level, as well as MOV energy requirement, thyristor surge current and their statistic characteristics are also presented to demonstrate the effectiveness of overvoltage protection control and active insulation coordination at Yi Feng TCSC.
