Abstract:It is to solve the problem that a large number of manual adjustments are required to meet the actual needs after the automatic generation of the existing one-line diagrams of the distribution network. Based on the automatic generation system of the one-line diagrams of the distribution network, a one-line diagram generation method combining an improved gravitation-repulsion algorithm and geographic coordinate information is proposed. The block method is used to reduce the dimensions of the layout, and the gravitation-repulsion algorithm is further optimized in combination with geographic coordinate information. This paper determines the main line based on geographic information, adaptively adjusts the length of the natural connection between nodes, and limits the movement direction of the node through the relationship between the parent node and the child node, and completes the automatic generation of the feeder single-line diagram of the distribution network. The feasibility of the method is verified by comparing the simulation and the results before optimization. The results show that after optimization, this method can generate a distribution network feeder single-line diagram with uniform line length and rich information. It is clear and easy to read, and meets the real-time requirements of power grid enterprises for the single-line diagram automatic generation method.
