Abstract

Abstract: The development of digital power grid puts forward higher requirements for distribution network planning. A distribution network reliability evaluation method based on graph-model integration technology is proposed, which can improve the efficiency of power network planners while improving the visualization and precision of distribution network reliability evaluation. This method is based on graph-mode integration technology, and a scalable vector graphics (SVG) map is proposed as a visual interactive object to map the planning content of the simulation on the feeder’s SVG map to the common information model (CIM). Based on the CIM, the distribution network topological model is built, and the feeder and load point reliability index solved using the fault diffusion traversal algorithm. Finally, by simulating the feeder planning transformation of a certain area, the reliability index changes before and after the feeder planning are given, showing that this method is effective and practicable. This method can effectively improve the efficiency of reliability evaluation of various distribution network planning projects by planners and provide important support for distribution network analysis, distribution network planning scheme evaluation, benefit evaluation of distribution self-healing project construction and so on.

Key words: graph model integration, visualization, scalable vector graphics, common information model, reliability of distribution network
