【Abstract】 To apply neural network to transient stability control decision in large scale power systems, a linear neural network for feature extraction and the sub neural networks dealing with different situations and the Polak-Ribiere-Poiyak conjugate gradient method for simultaneously training the neUral networks are proposed. The simulation results of generator shedding decision for a real 49-machine 248-bus system illustrate the perspective of the application of neural network to transient stability control in large scale practical power systems.更多还原
