A Through Type In-phase Power Supply System and its Principle Analysis
In response to the problems of negative sequence and discontinuous train power supply caused by electrified railway phase separation,a virtual through phase power supply system based on substation phase power supply and automatic ground passing through phase separation in section post is proposed.At the same time,the core unit functional requirements and corresponding control principles are proposed.This system can not only solve the problem of negative sequence and other power quality issues,but also achieve continuous power supply when the train passes through the neutral zone under the condition of segmented contact network,improving the power supply capacity and quality of the traction network.The simulation results have verified the effectiveness of the virtual through type in-phase power supply system.
