阳城-淮阴输电工程次同步谐振及MOV作用的研究

Study on SSR and MOV in Yangcheng Huaiyin Transmission System

为研究山西阳城至江苏淮阴输电工程引发次同步谐振（ＳＳＲ）的可能性，采用ＮＥＴＯＭＡＣ软件包进行了时域仿真研究，认为该系统中的串联电容补偿装置不会引起附近机组的次同步谐振，同时分析了金属氧化物可变电阻（ＭＯＶ）在系统故障期间的特殊作用。

The paper applies the time domain method to determine the possibility of subsynchronous resonance(SSR)in the Yangcheng Huaiyin Transmission System with series capacitors by means of NETOMAC. The results show that subsynchronous resonance will not occur in the generators neargy the system. The influence of metal oxide varistors(MOV) during transient period are also analyzed in the paper.
