<P>PROBLEM TO BE SOLVED: To make a desired system stabilization control device of each power plant control system stabilization without using a terminal device and a transmission channel. <P>SOLUTION: The system stabilization system is constituted such that: power plant bus bars BA, BB are connected via cables to an intermediate bus bar B4 connected to a main system via a cable, respectively; the system stabilization control devices 10A, 20B are arranged in a plurality of the power plants 1, 2, respectively, which are constituted of a plurality of generators connected to the power plant bus bars via blockers CB, respectively; the own system stabilization control device of each power plant is autonomously operated when an accident occurs in the cable; and the plurality of generators in the self power plant are controlled so as to selectively be cut off from the power plant bus bar of the self power plant by the blockers. It is determined whether each system stabilization control device is in a mode that the generator in the self power plant is cut off from an electricity amount at a self-end in the occurrence of the accident, and when it is determined that the device in not in the mode that the generator of the self power plant is cut off, the generator cut-off control of the self power plant is locked. <P>COPYRIGHT: (C)2007,JPO&INPIT |
