ELECTRIC LOCOMOTIVE CONTROL DEVICE AND ELECTRIC LOCOMOTIVE CONTROL METHOD

摘要

[Problem] To provide an electric locomotive control device capable of avoiding the degradation of service for passengers even when a power supply device for supplying power to a passenger car fails.[Solution] An electric locomotive control device (100) comprises: a plurality of first conversion devices (2a, 3a, …) for supplying power for controlling the driving motors (7a, 8a, …) of a passenger/freight car towing electric locomotive; a plurality of second conversion devices (6a, 6b) for each supplying power for a passenger car; a power conversion circuit (21) for converting the power of a specific first conversion device to the power for the passenger car through an insulating transformer (24); and a control unit (30) for, when one of the second conversion devices fails, performing control so that one of the first conversion devices is separated from the driving motors, connected to the power conversion circuit, and used as a substitute.
