ABSTRACT OF THE DISCLOSURE A stabilizing equipment for a power transmission system having a power source system, at least one transmission line and at least one line circuit breaker inserted between said power source system and said transmission line for interrupting said transmission line when a fault occurs on said transmission line, and said stabilizing equipment comprising a fault detector for detecting said fault, a series damping resistor, first means for inserting said series damping resistor between said power source system and said line circuit break before said line circuit breaker is interrupted and after said fault is detected by said fault detector, a parallel damping resistor, second means for inserting said parallel damping resistor between said power source system and the ground after said line circuit breaker is interrupted, and third means for separating said parallel damping resistor first and subsequently said series damping resistor before said line circuit breaker is reclosed after reclosing conditions are satisfied. According to this invention, a transient stability of the power transmission system is improved even if the transmission line is interrupted long after the occurrence of the fault, for example, by a back up protective relay.
