To provide a power conversion system for an electric railway capable of improving operation continuity at the time of occurrence of short circuit in an AC feeder circuit when a power conversion apparatus, which supplies the electric power to the AC feeder circuit of an electric railway, is independently operated.
The power conversion system for an electric railway applies an AC output of an inverter 1 to the AC feeder line for the railway by a constant voltage to supply the power to the load connected to the AC feeder line, and includes a controller 3. The controller subtracts a proportional value from an output of a voltage control device provided for generating a gate pulse of the inverter 1, the proportional value presenting a value proportional to an instantaneous value for the excess when the AC output current of the inverter 1 exceeds a constant value between a rated current and an overcurrent protection level.
