Abstract: In view of the limitations of traditional reliability assessment methods about on the main electrical connection of the substation, Bayesian network was applied to the reliability assessment and optimization of main electrical connection of substation. For this purpose, the example selected of two kinds of common main connection mode. Firstly, decomposed system according to the structure and function and obtained the logic diagram. Secondly, determined the minimum path from generator to the load and established the Bayesian networks which the function module was the node. Finally, calculated the system availability on basis of the Bayesian networks and found the weak links of reliability in the two main electrical connection. Calculation results show that the Bayesian network can help engineers to choose substation main electrical connection and guide maintenance work in the future, has a greater practical significance.
