Calculating reliability indices of open - loop distribution networks based on the state method

Abstract

– The open-loop power distribution networks have been increasingly developing to improve the reliability of power supply to the load. This research proposes a new scheme to calculate the reliability of the loop distribution networks. The proposed scheme is developed by combining the use of the state method and the analysis of the components’ failure effect on the loads. Each state of a component corresponds to a supply state of the loads (live or outage) and the classification of these states will be carried out by analyzing the path from the source to the load. By combining the states, the supply state parameters of the loads are calculated. From this, the distribution network’s reliability indices are calculated according to the IEEE-1366 standard. With the proposed algorithm, the author has developed a Matlab-based program to calculate the reliability indices of a sample open-loop distribution network consisting of 15 loads, 2 sources. Calculation results are also presented in this article.
