PROBLEM TO BE SOLVED: To add a compensation function for power fluctuation by using an inverter device, etc., in common. SOLUTION: This device is provided with a power fluctuation monitoring means, which monitors and detects power fluctuation at a receiving point 9, in accordance with the measurement results of the voltage of the injection point 14 of an intermediate order harmonic current and the current of a service entrance line, a power compensating means which generates the injection signal of a compensation power, which cancels the power fluctuation in accordance with the detection result of the power fluctuation, and an inverter device 18, which is controlled to drive with a signal obtained, by adding the injection signal of the compensation power to the injection signal of the intermediate order harmonic current and injects the intermediate order harmonic current and the compensation power into the injection point. |
