摘要： A station building power supply includes: a power converter that converts DC power to AC power; a casing that houses the power converter; an AC system circuit that supplies the AC power output from the power converter to electrical apparatus outside the casing; and a filter circuit that applies a high-frequency current generated in the power converter from the AC system circuit to the casing. In the station building power supply, the power converter and the casing are grounded.

摘要： The station-building power supply device includes a capacitor unit that stores therein surplus regenerative power, a first power conversion unit that performs DC/DC power conversion, and a second power conversion unit that converts DC power. A first voltage threshold for detecting the occurrence of surplus regenerative power is set and a first SOC threshold for detecting whether the capacitor unit can discharge is set. The first power conversion unit is controlled such that power is supplied from the feeder to the capacitor unit to charge the capacitor unit when the feeding voltage exceeds the first voltage threshold, and the second power conversion unit is controlled such that power is supplied from the capacitor unit to the station loads when the SOC of the capacitor unit exceeds the first SOC threshold.

摘要： A station building auxiliary power unit includes a start-of-operation determination unit that determines, based on a first signal that represents information on a power flow direction indicating a direction of flow of electrical power between an AC distribution line electrically connecting to an electric vehicle and a substation for supplying AC power to the AC distribution line, whether first AC power on an AC distribution line side is to be transformed into second AC power usable by a load, and if it is determined that transformation is to be performed, generates and outputs a second signal, a voltage instruction value calculator that calculates and outputs a voltage instruction value corresponding to the second signal, and a PWM signal generator that generates a control signal for a power converter circuit operated upon transformation of the first AC power into the second AC power, and outputs the control signal.

摘要： The present invention relates to a station auxiliary power source apparatus that converts power supplied from an overhead cable to generate power to be supplied to a load in a station. The station auxiliary power source apparatus includes a first average calculation unit that calculates the average value of the overhead cable voltage for every predetermined time period; a second average calculation unit that calculates, two or more times, an average value of the overhead cable voltage that is larger than a first average value of the average value among the overhead cable voltages; a third average calculation unit that calculates an average value of the overhead cable voltage per day; and a comparator that selects any one of a second average value of the average value and a third average value of the average value and sets the selected value as the threshold value.
