Abstract: The research on the reliability of distribution network uses simulation method or analytical method widely. The existing analysis methods for distribution networks usually require network topology analysis for a single node. Based on the topological relationship of low-voltage distribution network, this paper proposes a new analytical model for low-voltage distribution network. Firstly, using the relationship between the upstream and downstream nodes of the line, an algebraic equation of the expected blackout time and the expected blackout frequency of the entire network could be construct. Secondly, the expected power outage time and the expected power outage frequency at each load point can be calculate. Finally, the average availability index and load loss expectations of the entire network are calculate from the expected power outage frequency and expected power outage time at each load point. The model proposed in this article can determine the reliability index of each load point using fewer algebraic equations, and the calculation is fast and accurate, which can provide a reference for the planning and operation of distribution.
