A new method using ANN for contigency reactive power voltage prediction is proposed. The training set is composed of the result of load flow computation at different topologies, and the ANN model for contigency voltage prediction is established. The results applied to Ward & Hale 6 nodes system proves that the ANN model can work quickly and accurately.
