摘要

针对连州发电厂3号机静止可控硅自并励发电机失磁保护出现的转子电压显示值比实际值大的问题

分析自并励发电机转子电压波形所具有的特点和部分微机型发电机保护装置转子电压采集回路的原理

找出了该保护装置转子电压测量不准的原因

并提出了解决办法。该办法经实施

效果良好。

Abstract

Directing against the problem of displayed value for rotorvoltage was greater than actual value occurred in fieldloss protection of the selfshunt excitation generator with stationary thyristors for unit NO.3 in Lianzhou Power Plant

the features being possessed of rotorvoltage waveform for generator with said excitation mode and principle of the rotorvoltage acquisition circuit for some generator’s protection facilities operated by microprocessor being analysed

the causes leading to not accurate measurement of rotorvoltage for the said protection facilities being found

and solving measures being put forward. After implementation of said measures

good results have been obtained.
