<P>PROBLEM TO BE SOLVED: To enhance the quality of power supplied to a load in an interconnection power generation system where a generation power system including an AC generator and a commercial power system are interconnected by suppressing output variation of the generation power system resulting from voltage disturbance. <P>SOLUTION: A phase shift occurring between an output voltage applied to a load 4 and an output current from a generation power system 3 is corrected by inserting a voltage source 8 into the main line route 6 of the generation power system 3 and imparting a compensation voltage from the voltage source 8 to the main line route 6. More specifically, a compensation voltage (V<SB>C</SB>) is imparted to the voltage generated from the AC generator such that the phase of a voltage (V<SB>L</SB>) flowing through an interconnection reactor 7 provided in the main line route 6 delays by 90° behind the phase of a voltage (V<SB>S</SB>) from a commercial power system 1. Since the phase of the output voltage applied to the load 4 matches the phase of the output current from the generation power system 3, high quality power can be supplied to the load 4. <P>COPYRIGHT: (C)2008,JPO&INPIT |
