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 8):
A DC-feeding-voltage calculating apparatus connected to a substation that supplies electric power to a feeder in a DC electrified section of an electric railroad and a voltage sensor that measures a voltage value of the feeder, the DC-feeding-voltage calculating apparatus calculating a substation voltage applied to the feeder,\n the DC-feeding-voltage calculating apparatus comprising: a model-information storage to store model information, the model information including train model information, feeding network model information, and substation model information, the train model information including information for controlling a regenerative power reducing amount in a train existing in the DC electrified section, the feeding network model information including position information on the substation and the voltage sensor, the substation model information including control information on the substation voltage; a train-operation-information estimator to estimate second train information on the basis of the model information, a voltage value measured in the substation, current values of feeders by train direction, the voltage value measured by the voltage sensor, and first train information on a train equipped with a wireless communication apparatus, the current values of the feeders being measured in the substation, the second train information is 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; and a substation-voltage-setting-value calculator to calculate, on the basis of the model information and the train operation information, 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 substation-voltage-setting-value calculator outputting the substation voltage setting value to the substation.
