Abstract

This paper proposes two Neural Networks (NNs) based approaches for on-line power system TRANSIENT STABILITY EVALUATION (TSE). The first approach represents the application of FEEDFORWARD NEURAL NETWORKS in estimating the critical clearing time (t cr) for TSE. The second one presents a similar effort using the Kohonen neural network. Knowing that for a particular fault scenario, tcr is a function of only pre-fault system operating point, the main objective of the first approach is to investigate the way that one may develop a feedforward neural network based method to approximate this function by considering the smallest set of directly monitorable variables which characterize the pre-fault operating point adequately. In the other approach, it is shown that the small amount of changes in the pre-fault conditions leads to the small amount of changes in the tcr . So, a Kohonen neural network is used for the classification of the pre-fault conditions and estimation of the tcr. The proposed approaches have been successfully applied to a three-machine test system. The difficulties of using the Kohonen netbased approach in large POWER SYSTEMS are also explored.
