Study on capacity calculation of regenerative inverter for DC electrified transit substation

This paper presents capability calculation methods for regenerative inverter in DC electrified transit system. The proposed method uses a train performance and power simulation tool to calculate the regenerative power generated in the DC substation and decide the capability of regenerative inverter. The capability of regenerative inverters for Seoul subway line 5, 6, 7, and 8 has been calculated.
