<P>PROBLEM TO BE SOLVED: To provide a stabilization device for a power system capable of properly selecting a control object necessary for stabilization so as to stabilize a transient stability and resolve an excessive rise of voltage, and capable of effectively selecting the control object; to also provide a control method thereof. <P>SOLUTION: An unstable phenomenon determining part 103 determines stability and an occurrence of excessive voltage rise for each possible accident based on a calculation result of a calculation execution part 102 for transient stability. A generator selection part 104a selects a generator to which a cut-off control is to be executed when the unstable phenomenon determining part 103 determines that the stability is unstable. A selection part 104b for selecting a phase-modifying device selects a phase-modifying device when the unstable phenomenon determining part 103 determines an occurrence of excessive voltage rise. <P>COPYRIGHT: (C)2012,JPO&INPIT |
