摘要： The invention provides a railway vehicle comprising a switching device and an electric storage device, and when contact break between an electric power line and a power collector occurs, the switching device is activated to perform charging or discharging of the electric storage device, wherein after the vehicle recovers from the contact break state, the switching device is stopped so as to cut down fruitless consumption of energy. The control system of an electric vehicle comprises a switching signal output device composed of a DC voltage detector for detecting a voltage value of a power converter for controlling the operation of a main motor and a contact point of the switching device, a travel distance computing device for computing a travel distance of the main vehicle, and a contact break position database storing in advance the position in which contact break occurs, wherein the device predicts entry of the vehicle in a section where contact break occurs by verifying the travel distance value and the contact break position database, and outputs a switching signal. The switching device is activated or stopped based on the switching signal.

摘要： A typical traction system that does not have a storage battery device for a direct-current power unit of a main circuit cannot ensure exciting energy necessary upon activation of an induction generator. Thus, there is a problem that the typical traction system cannot use a small, inexpensive, and highly reliable induction generator as a power generator. A railway vehicle traction system includes an induction generator to be driven by an engine, a first power converter for converting alternating-current power output from the induction generator into direct-current power, a smoothing capacitor for smoothing the direct-current power output from the first power converter, a second power converter for converting the direct-current power output from the smoothing capacitor serving as a direct-current voltage source into alternating-current power and driving an electric motor, storage battery means for supplying power to an on-vehicle control device, and a contactor that is connected between the storage battery means and the smoothing capacitor. By closing the contactor, the smoothing capacitor is charged by the storage battery means, and whereby a current is supplied to the induction generator in order to start an operation of generating power using power charged in the smoothing capacitor.

摘要： There is provided a railway system enabling a railcar including an onboard power storage to run to a nearest station with the minimum capacity of the onboard power storage. The power storage is installed on the railcar and inter-station power feeding equipment is provided. The inter-station power feeding equipment is a power supply facility using a contact line or charging post fed with power from a power supply system different from the power supply system of a contact line near a station. The distance between the station and the inter-station power feeding equipment or the distance between the inter-station power feeding equipment and the inter-station power feeding equipment is within an operating range over which the train can run with the maximum state of charge of the power storage. The onboard power storage can be charged at a location where the inter-station power feeding equipment is provided. Thus, the railway system can reduce the capacity requirements of the onboard power storage and enables the railcar to run to the nearest station.
