| Abstract: | This paper presents the reliability evaluation model of the HVDC flexible system based on the basic principle of Markov processes and the properties of the transitional frequencies among cumulative states.Then the weak link in the HVDC flexible system is analyzed by the quantitative analysis method,and the enhancing measures are given.The reliability indices are analyzed and compared at different spare levels,and the result shows that the reliability and economic indices of sthe ystem are well under one spare. |
