摘要

Reliability evaluation combines the concept of severity of the accident consequence and the likelihood of it occurring. The severity of the accident consequence caused by transmission lines malfunction has rarely been considered in the existing contingency screening technique. This paper proposed a fast contingency filtering technique for transmission system reliability evaluation based on vulnerability analysis. The influence of faulty transmission lines on the severity of accident consequence is described by functional factors based on the vulnerability analysis. The sequence of transmission lines is ordered by the severity coefficients determined by state probabilities or functional factors of the faulty lines or both of them. Contingency states are searched and ranked based on the sequence of transmission lines. Three severity coefficients for a line are defined and examined based on reliability and functional factors. The merits of the proposed techniques and severity coefficients are validated by evaluating the IEEE-RTS79 test system.
