Optimal Allocation Of Efficiency In Distribution Network Fault Rush-repairing Based On Genetic Algorithm

Distribution network repair efficiency has a direct impact on power supply reliability,the regional economic effects and social stability,thus to enhance the efficiency of distribution network repair is of great importance.In this paper,based on the analysis of the status quo of domestic and international distribution repair,on account of genetic iterative algorithm,starting from the economic,overall,and systematic point of view,studies the effective means to improve the repair efficiency of distribution network by means of stagnation optimization,system improvement and process specification.The main research work and achievements are as follows:1)Compared with the domestic and foreign distribution network repair system,according to the characteristics of China's urban distribution network,collect and analyze of urban distribution network repair efficiency of a number of factors.Based on the analysis of each factor,put forward the problems of repairing system in urban distribution network.2)Establish a data model based on genetic algorithm toolbox to solve the existing situation of repairing regional distribution network.Considering the main factors influencing the efficiency of distribution network repair based on the urban intensive load region,the model takes into account the global efficiency and economic impact.According to the application performance of the model,a constraint condition is established to optimize the demand and engineering practice.3)Considering the effect of multiple faults in city distribution network on the efficiency of repairing,this paper combines the regional geography diagram to complete the calculation of GA optimal solution.Based on the genetic algorithm toolbox,this paper analyzes the model of the distribution network repairing system.Based on the comparison of the optimal repair configuration and the existing emergency repair configuration,the paper evaluates the economic and efficiency of the data.Network repair in the global configuration with better efficiency and economy,to meet the network repair work efficiency,improve the economic requirements.4)From the regional point of view,the search for efficiency improvement space for the network repair process under the power grid fault,matching with the network based on GA optimization of the distribution network repair,design of distribution network repair command center construction program and a set of quantitative dynamic assessment system.The design has achieved significant economic and social benefits in practical engineering applications.This paper makes thorough analysis of the distribution network fault repair process and explores efficiency short board,puts forward the global technology and the remedy measures of the management direction in the network fault,the process does not need to increase the existing basis of stagnation,the installation of an additional upgrade equipment,verified by simulation,the efficiency has been improved.
