Line S1 of Wenzhou Commuter Rail adopts the operation mode of bus rapid transit, which requires high control of train running speed, great traction load, and the train operation safety is unable to be guaranteed when the train is passing through automatically the phase break. With adoption of co-phase power supply technology, it is able to cancel the phase break at exit of substation and may solve the problems of negative sequence. The paper, with the single phase combined co-phase power supply system as an example, introduces the structure and principles of combined co-phase power supply system, and through simulation and analysis are made by establishing of a single phase combined co-phase power supply system model based on related traction design data, the simulation results show that the system has a better effect for control of negative sequence.
