ABSTRACT:
In a power system wherein a plurality of power plants, load systems and power transmission components are connected to each other for increasing the power transmission capacity of the power system, the power system is stabilized and power swings are suppressed, by controlling a semiconductor switch used in a power system stabilizing apparatus which is provided at the power system in an applying manner adequately corresponding to its operation characteristics and function, in accordance with a stabilizing command signal generated by using state values (for example, voltage, current, power, frequency, phase angle) of the power system, detected by detecting circuits provided in the power system.
