Title:
AC FEEDER EQUIPMENT FOR ELECTRIC RAILWAY
Document Type and Number:
Japanese Patent JP2001354052
Kind Code:
A
Abstract:
To preclude an antiphase component from flowing into a three-phase AC power system, and reduce a voltage drop caused by a line impedance.
A three-phase AC electric power of the electric power system 1 is converted into DC electric power of a prescribed DC voltage by an ac-to-dc converter 4 to be transmitted to an dc-to-ac inverter 7 provided in a feeder substation 6 via a DC circuit 5. The DC electric power transmitted via the circuit 5 is converted into an AC electric power of a prescribed single phase AC voltage in the inverter 7 to be supplied to an alternating current feeder circuit.
