Title:
The driver system for rail cars
Document Type and Number:
Japanese Patent JP6186231
Kind Code:
B2
Abstract:
A railway vehicle with an engine power generation drive system operates with reduced engine noise at a station platform without restricting the engine power necessary for the drive of the vehicle. The drive system comprises an engine driven power generator that supplies AC current to a first traction converter, which itself supplies DC current to: a second traction converter that controls an electric motor; and to a third traction converter that supplies power to auxiliary apparatus (e.g. air-conditioning). Based on information obtained from the three converters, a control device gives an operating command to reduce power consumption of the auxiliary apparatus, from when the vehicle starts from a station until it departs the station platform. A train information control system detects the starting status of the vehicle, when an entrance door shifts from the open to closed and the rotor frequency (absolute value) of an electric motor calculated by an inverter device shifts from zero to a positive value. The station-platform running distance is calculated and the mileage after the start from the station is calculated by integrating the rotor frequency from the time point of the start from the station. Until the mileage exceeds the station-platform running distance, operation of service equipment is restricted to reduce power consumption.
