Abstract :
Power quality pollution to power system and locomotive´s discontinued current collection are caused by two phase traction power supply system in electrical railway. Cost-effective co-phased traction power systems (CTPS) consisted of balanced transformer, active power flow controller device (APFC) and passive compensation device (PCD) was presented to reduce power quality pollution and guarantee locomotive´s current collection continuously by canceling neutral section. Two schemes of CTPS were compared, parameter calculating method of PCD and control strategy of APFC are analyzed. CTPS and its control strategy have been verified based on MATLAB simulation.
