Abstract For an important customer in the power system, there are more than one electricity supply path to maintain the supply reliability of the customer. Therefore, it is necessary to evaluate the real-time reliability of different supply paths considering various outage factors and locate the most reliable supply path. This paper proposes an improved evidence theory and presents a method to acquire the outage rate of electrical equipment considering various outage factors. The correlations between the various outage factors and critical outage factor are analyzed, and then an integrated outage rate model is established considering the subjective judgement and objective data based on the improved evidence theory. Subsequently, a method to find out the most reliable supply path is put forward. This outage rate model can be used to discover the potential outage components in the current operating condition, and also can be further used to search the higher reliability supply path for customers.
