PURPOSE: An integration power supply device for an electric power substation is provided to reduce time and cost for maintenance by easily grasping a part operated by mistake among all power sources which are necessary within the electric power substation. CONSTITUTION: A charge unit(1) changes alternating current voltage which is provided from systematic power into direct current voltage. A battery(2) having a plurality of cells is charged through output voltage of the charge unit. A dropper(3) for load voltage compensation supplies a power source for electric power substation control by using the output voltage of the charge unit and charging voltage of the battery as input voltage. A DCDC convertor unit(4) supplies a power source for electric power substation communications by using the output voltage of the charge unit and the charging voltage of the battery as the input voltage. An inverter(5) changes the charging voltage of the battery into alternating current voltage and supplies an alternating current source for electric power substation commercial. An integrated controller(6) polysynthetically controls the charge unit, the battery, the dropper for the load voltage compensation, the DC-DC convertor part, and the inverter.
