The outstanding power quality problems including three-phase voltage unbalance and large reactive power have drawn more and more attention of railway company and power system. Moreover, the neutral section insulators at exits of substations affect the safety and efficiency of the electric trains, especially in high speed railway and heavy haul railway. A new traction power supply system adopting Vx...
In conventional single-phase 25kV AC traction power supply system, there are some outstanding power quality problems including three-phase voltage unbalance and large reactive power. Moreover, the neutral section insulators at exits of substations affect the safety and efficiency of the electric trains, especially in high speed railway and heavy haul railway. In this paper, a new traction power supply...
