Research on Power Supply Reliability of Intelligent Distribution Network with Automatic Blocking Evaluation

The power system can provide users with continuous and stable electric energy. The power supply reliability evaluation of distribution network is a necessary link to ensure the stable work of power system. In order to study the influencing factors of power supply reliability of intelligent distribution network, this study proposes to realize automatic blocking of distribution network by node optimization number, and study the power supply reliability of distribution network by block. The results show that the performance effect of scheme IV is the best among the five schemes in terms of system negative reliability index and system positive reliability index. The closer to the tie line is, the higher the reliability of the load point index is. In other words, factors such as tie line, switch failure, unreliable fuse and maintenance of distribution network equipment will affect the power supply reliability of distribution network. It is hoped that the research results can provide a reference for the in-depth study of power supply reliability of distribution network.
