Power System Faults Diagnosis Based on Rough Sets-Bayesian Networks
Suxia Chen · Huagong zidonghua ji yibiao · 2011
A Rough Sets theory and Bayesian networks-based faults diagnosis method for the power system was proposed to obtain the minimal fault diagnosis decision-making tables of power system,and to have the fault characteristics of the power system reduced by making use of the rough set reduction algorithm,and have its Bayesian network constructed and the accuracy and efficiency of power system fault diagnosis improved by adjusting the weighting factor of the nodes in Bayesian network.Simulation results show that the proposed method is simple and practical.
