摘要
统计分析广州蓄能水电厂B厂静止变频器自然换相阶段过流故障现象及原因。基于实测及理论推断,指出其缺陷在于静止变频器逆变器逆变角β裕度不足。通过改进静止变频器的逆变角β,消除了过流故障模式。
The over-current faults in commutation process of Static Frequency Convertor （SFC） in the Plant B of Guangzhou Pumped Storage Power Station and its reasons are analyzed based on the statistical operation data. Based on measured data and theoretical analyses, the over-current faults are mainly caused by insufficient margin of inverter inverting angle β. The over-current faults are finally eliminated by adding the inverting angle β of SFC.
