Abstract

This paper presents a method for the reliability evaluation of distribution networks, including the influence of the weather on the failure rates of the components, and the possibility of preventive maintenance. A mixed technique combining the use of the minimal cut set method with a model based on Markov homogeneous processes of a discrete state-space and continuous parameters has been developed. This technique has been applied to several examples of distribution networks, including open-air, underground and mixed networks. Its efficiency has been proven by the comparison, in respect of both speed and accuracy, with other computational methods
