In recent years, complication of power system is progressing. Under such a situation, measures for high-speed stabilization are needed in order to prevent beforehand that the influence of the fault spreads for the whole system. If the fault occurs in power system, improvement of transient stability is expected by carrying out of generator shedding, i.e. some generators are separated temporarily. In this paper, the stability estimation system after generator shedding is constructed. Moreover, the neural network for selecting the suitable shedding generator taking account of stability after the fault was newly constructed.
