<P>PROBLEM TO BE SOLVED: To perform system-stabilizing control with relatively smaller SVC capacity, as compared with conventional types. <P>SOLUTION: In a system-stabilizing method which controls reactive power by means of a reactive power compensator 11, according to the voltage ripple of a power system where a capacitor 7 is connected to a bus 1 via a breaker 4, the leading compensating reactive power by the reactive power compensator 11 is suppressed, by turning on a capacitor 7 via the breaker 4 when the bus voltage drops, and the delayed compensative reactive power by the reactive power compensator 11 is suppressed, by paralleling off the capacitor 7 via the breaker 4 when the bus voltage rises. <P>COPYRIGHT: (C)2008,JPO&INPIT |
