摘　　要：In order to form an emergency control policy table quickly, this paper proposes a fast algorithm of emergency control named ＂micro-step discrete method＂, which is based on the physical meaning of the gradient and the discrete characteristics of emergency control. Then it is improved through the stability criterion, integral step, and micro-step factor. This paper takes generator-shedding as the emergency control measures. As the optimal generator-shedding control is essentially an optimal control problem and the generator-shedding variables are always constant, it is convenient to use the control parameter algorithm to solve the problem, which can calculate the gradient of the transient stability function to control variables.In order to form an emergency control policy table quickly, this paper proposes a fast algorithm of emergency control named ＂micro-step discrete method＂, which is based on the physical meaning of the gradient and the discrete characteristics of emergency control.
