| Abstract: | 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. |
