摘要
针对消弧线圈接地电网中普遍存在的谐振过电压问题,分析了正常运行时及断线故障时位移电压大小,比较分析了当前通常采用的几种解决方案,首次提出:通过调节消弧线圈挡位。
The over voltage based on resonance and line breakage fault is analyzed focusing on the problem of over voltage existing in petersen coil grounded system.A scheme of changing the parameter of system to eliminate resonance over voltage by adjusting petersen coil is presented for the first time.
