A connection topology and the corresponding current control strategy of photovoltaic (PV) generation for the traction power supply of electric railway are proposed. In this topology, a V/V transformer is used to convert two-phase traction voltage to three-phase voltage, which has the same amplitude and phase angle as the grid voltage. This can provide three-phase balanced voltage for the connection of PV generation. Then, an individual phase current (IPC) control strategy is designed in the three-phase stationary reference frame. In the proposed strategy, the phase current values are used as the controlled variables instead of the positive and negative sequence current components. Without any sequence extraction, it can flexibly inject both symmetrical and asymmetrical current by closed loop control of the phase current. In this way, the PV generation system can operate in two modes: one is the self-generation and self-consumption operation for supplying the locomotive, and the other is the grid-connection operation for feeding back to the grid. Finally, simulation results validate the effectiveness of the connection topology and the IPC control.
