| Summary: | Segmentation is an important factor affecting the reliability level of medium voltage overhead lines. How to determine the optimal number of segments of medium voltage overhead lines is one of the difficulties in distribution network planning. Different from the assumption that users are evenly distributed in the past reliability analysis, this paper further analyzes and discusses the influence of uneven distribution of users on the reliability level and optimal number of sections of medium voltage overhead single radial lines. Firstly, the mathematical model of different user distribution is established, and then the quantitative calculation formula of reliability index and optimal number of segments under different user distribution is derived based on analytical method. Furthermore, the expression of optimal number of segments considering user distribution is proposed considering economy and reliability. The simulation example verifies the correctness of the theoretical derivation. |
