改进贝叶斯网络GO法在高压直流输电系统的可靠性分析
Reliability Analysis on HVDC Transmission System Based on Improved Bayesian Networks GO Methodology
摘要
Abstract
Aimed at the deficiencies of Bayesian network GO methodology,which is only applicable to simple immutable system reliability analysis,an improved Bayesian network GO methodology is proposed in this paper.In order to make it adapt the reliability analysis of complex repairable high-voltage direct current (HVDC) system,the algorithm constructed the equivalent element method of the serial and parallel correlation structure in the Bayesian network and changed the model mapping rules based on the actual operating mode and the correlation of the components.The method is verified by quantitative calculation in the establishment of HVDC system reliability model.The results show that the improved algorithm is feasible,it only needs multiple Bayesian network inference to directly calculate the reliability of the equivalent unit,without taking into account the shared signal and complicated GO operation.Bayesian network can also be used to find the weak link of the system reliability.Compared with the traditional GO methodology,this method has obvious advantages.关键词
