Fault Location Method and Case Analysis of Distribution Network Based on Logic Operations
In order to improve the accuracy of fault location in distribution network,aiming at the shortcomings of traditional algorithm model in fault section location,a fault location method based on logical operation is proposed.Logical operation is used to describe the causal relationship between nodes and sections,and a numerical calculation model for fault location is constructed.The simulation results show that the accuracy of particle swarm optimization algorithm and deep learning algorithm does not reach 100%,and the minimum recall rate of particle swarm optimization algorithm is 84%,while the location accuracy and recall rate of logical operation method for single fault in different preset fault areas are both 100%.Therefore,the distribution network fault location method based on logical operation proposed in this paper has the highest accuracy and good application value.
