Abstract: A breaker 162 is opened when a pantograph 101 is lowered. The pantograph 101 is connected to an overhead wire 200. Voltage and its phase of the overhead wire are detected by a detector 161. Power is supplied from a power storage device 150c to a tertiary winding 112c via a power converter 14c such that a primary side of the main transformer 110 has the same voltage and phase as the overhead wire so as to reversely excite the main transformer 110. When the voltage of the main transformer 110 has the same phase as the voltage of the overhead wire 200, the breaker 162 is turned on and then the pantograph 101 is raised, to connect the overhead wire 200 and the main transformer 110 to each other, thereby preventing the occurrence of an excitation inrush current to the main transformer 110.

Abstract: Frequent charging/discharging to an electric energy storage element is suppressed for energy saving and longer lifetime. A transmission-line-side power converter device converts power from a transmission line, and supplies DC power to a feeder line connected to an electric energy storage element. An output current controller connected with a line voltage detector detects the feeder line voltage, and a charging rate detector detects a charging rate of the electric energy storage element. A control table sets charging/discharging start voltages and current saturated voltages based on the detected line voltage and charging rate. The output current controller controls the electric energy storage element to discharge at a high line voltage as the charging rate increase, to suppress charging the electric energy storage element at the low line voltage, and makes discharging difficult at the low line voltage to facilitate charging at the low line voltage as the charging rate decreases.
