摘要
Abstract
According to the complicated topology of transmission grid and the uncertainties of the alarm information after fault, this article proposes a distributed power grid fault diagnosis method based on Bayesian networks. The distributed element diagnosis model and combined diagnostic model of line, transformer and bus were constructed and de-laminated. The suspicious faulty components were inferred from the element diagnosis model that combined with the SCAD A/RMS (relay management system) system message. Then, through the reasoning of combined diagnosis model , the faulty components of power system were achieved, which fit the maximum posterior probability. Calculation examples prove that the proposed method is correct and available.关键词
