Abstract:
A DC-feeding-voltage calculating apparatus includes storage that stores train model information including information for controlling a regenerative power reducing amount in a train in an electrified section; feeding network model information including position information on a substation; and substation model information including control information on a substation voltage. On the basis of: the stored information; a voltage value, current values of feeders by train direction, the voltage and current values being measured in the substation; and first train information on a train including a wireless communication apparatus, an estimator estimates second train information on a train not including a wireless communication apparatus and outputs train operation information. A calculator, on the basis of the stored information and the train operation information, calculates a substation voltage setting value for controlling the substation voltage such that regenerative power is increased in a regenerative car in the electrified section.

Claim (Index 9):
A DC-feeding-voltage control system that controls a substation voltage applied to a feeder in a DC electrified section of an electric railroad,\n the DC-feeding-voltage control system comprising: a voltage sensor and current sensors set on feeders by train direction; a wireless communication apparatus mounted on a train; and a DC-feeding-voltage calculator, wherein on the basis of: information concerning a voltage value measured in a substation and current values of the feeders by train direction, the current values of the feeders being measured in the substation; information concerning an on-rail position, a voltage value of a pantograph point voltage, a current value of an electric current supplied from an overhead line, the on-rail position, the voltage value of the pantograph point voltage and the current value of the electric current supplied from the overhead line being measured in the train; and model information including position information on the substation, the DC-feeding-voltage calculator calculates a substation voltage setting value for controlling the substation voltage such that regenerative power is increased in a regenerative car existing in the DC electrified section, the DC-feeding-voltage calculator outputting the substation voltage setting value to plural substations that supply electric power to the feeders, wherein the DC-feeding-voltage calculator includes a train-operation-information estimator to estimate second train information on the basis of the model information, first train information, the voltage value measured in the substation, and the current values of the feeders by train direction, the first train information being information on a train equipped with a wireless communication apparatus, the second train information being information on a train existing in the DC electrified section and not equipped with a wireless communication apparatus, the train-operation-information estimator outputting train operation information including the first train information and the second train information.
