摘要
广州珠江电厂励磁系统主备励切换时无功功率常常会出现大幅波动,处理不当甚至还可能引起跳机事故的发生。根据三相桥式全控整流电路原理分析了珠江电厂主、备励切换时无功功率大幅波动的原因,并且提出了相应解决的方法。
In Zhujiang Power Plant, on- line- switching between AVR and reserve excitation will cause fluctuation of re.active power, even the break trouble of generator if without proper management. Based on the principle of phase- control rectifier circuits with three- phasebridge type, the authors probe into the reasons of the fluctuation and put forward relative solutions.
