A plurality of voltage compensation circuits P1-P3, N1-N3 converts DC voltages accumulated in a capacitor 11 having respectively different charging voltages (which is 2K times of the minimum voltage (K=0, 1, 2, . . . )) into AC voltages. The plurality of voltage compensation circuits are connected to the electric power system in series. When the voltage dip occurs in an electric power system, a desired combination is selected from the plurality of voltage compensation circuits P1-P3, N1-N3. The total sum of the output voltage compensates the voltage dipped. At the normal time, the high speed mechanical short circuit switch by-passes the voltage compensation circuits to reduce apparatus loss.
A voltage fluctuation compensating apparatus for suppressing fluctuation of a voltage supplied to a load, comprising:
A voltage fluctuation compensating apparatus for suppressing fluctuation of a voltage supplied to a load, comprising:
A voltage fluctuation compensating apparatus connected to an electric power system, the voltage fluctuation compensating apparatus for monitoring a voltage dip of the electric power system and controlling the electric power supply based on the monitoring to output a compensation voltage to compensate the voltage dip of the electric power system and to suppress fluctuation of the voltage to be supplied to the load, the voltage fluctuation compensating apparatus comprising:
