Abstract: Power system component fault diagnosis problem is a key issue in case of the failure of the power system. A Bayesian network, in which the network parameters are learnt by a particle swarm optimization algorithm, is proposed in this paper to establish the statistical diagnosis model. The Noisy-Or and Noisy-And structure are employed to construct the framework of the model, where the 4-level Bayesian network makes the fault prediction with properly given parameters. In order to verify the performance of our proposed method, a typical power system component fault diagnosis problem is used for empirical case study, and the result demonstrates the effectiveness of the proposed method.

Keywords: Power system; component fault diagnosis; Bayesian networks; parameters learning; particle swarm optimization
