Research on Optimization Method of Distribution Network Topology Structure Supported by GIS Spatial Data
Aiming at the shortcomings of the traditional distribution network topology,such as high failure rate and long execu-tion time.In order to improve the structural stability and execution speed of the distribution network,an optimization method of the distribution network topology based on GIS spatial data is studied.The method collects the actual spatial location and e-lectrical performance parameters of equipment lines,converts them into GIS spatial structure data,and constructs a GIS spatial data distribution network model.Based on the k-means algorithm,it clusters the data of the distribution network,extracts the optimal dataset for region division,uses the minimum path method to shorten the execution structure of the distribution net-work,simplifies the equivalent topology structure of the coverage area according to the distribution network load distribution,accurately improves the load performance of the distribution network and reduces the operational failure rate of the distribution network structure.Through experiments,it has been proven that the comprehensive failure rate of the distribution network op-timized by GIS spatial data has been reduced to 7％,with a unit execution step count of less than 2000 steps and an execution time improvement of nearly 90％compared to traditional structures,which makes the optimized offset topology structure more stable and higher execution efficiency.
