【Abstract】 Breaking resistor is considered to be useful in transient stability.This paper addresses a control strategy based on extended equal area criteria EEAC .The controller design is transform ed into a static optim ization problem.Then the maximum stability region is regarded as objective function,and the optimization problem is solved via a genetic algorithm GA .The simulation results show that the control strategy is easy to be implemented,the design methodology is practical and the effect is desirable.更多还原
