Abstract

PURPOSE:To enable the operating power-factor of an inverter to be kept to be almost 1, by controlling the voltage type self-exciting inverter performing continuous system operation with a distribution system, so that the absolute values of the voltage of the distribution system and the output voltage of the inverter may be equal to each other. CONSTITUTION:A distribution system 4 and a voltage type selfexciting inverter 2 are connected to each other via a continuous system reactor 7, to perform continuous system operation. In its case, first, by a transformer 10, the voltage of the distribution system 4 is detected, and by a transformer 8, the output voltage of the inverter 2 is detected. Then, the inverter 2 is contrived to be controlled so that the absolute values of two sorts of the detected voltage may be equal to each other. As a result, the operating power-factor of the inverter 2 of a continuous system point can be kept to be almost 1.
