Analysis and Application of Fault Location Technology in Distribution Network
In order to reduce the problem of fault location error in distribution network caused by abnormal current state analysis,the analysis and application of fault location technology in distribution network are proposed.Combined with the relationship between the direction of fault current flow and the direction of main power supply current flow,the fault current in distribution network is coded,and the adaptability of current state to the operation state of distribution network is taken as the benchmark to determine the adaptability value of fault current in distribution network under the current code,gradually narrow the fault range and achieve positioning.In the test results,the design foundation positioning precision is the highest,and the accuracy is the most reliable.Compared with the control group,it is significantly more stable.
