摘要
潮流控制器(PFC)用于同相牵引供电系统中,具有传递有功、补偿无功、消除谐波等功能。分析了潮流控制器在各种故障情况下的状态变化。针对故障特征,在潮流控制器自带的脉冲封锁保护基础上,增加了过电流保护和失压保护。
The Power Flow Controller（PFC） is applied to improve the power quality in the cophase traction power supply system. The behaviors of PFC under all kinds of faults occurring situations is analyzed. Based on the pulse blocking protection,over-current protection and under-voltage protection are proposed.
