Summary: | The invention provides an electrified railway traction power supply system and a photovoltaic power generation split-phase current control method thereof. The method comprises the following steps: obtaining active power output by a photovoltaic inverter; calculating a positive sequence current reference value of the photovoltaic inverter based on the active power; calculating a negative sequence current reference value of the photovoltaic inverter based on the load power of the traction load; the output current of the photovoltaic inverter is controlled to track the positive sequence current reference value and the negative sequence current reference value in an error-free mode, so that active power is output to a traction load through the photovoltaic inverter, the third transformer, the low-voltage alternating-current bus and the second transformer in a photovoltaic mode; and the photovoltaic inverter compensates the negative-sequence current of the high-voltage alternating-current power grid caused by the |
