摘要
Abstract
The distribution network has a complex line structure,and access to distributed power sources makes it difficult to locate faults.In order to solve the problem,the network topology is layered.Based on the existing traveling wave ranging and locating methods,it uses multi-terminal traveling wave information to filter out important wave head data,and then the wave head time difference is brought into the double-ended ranging formula to locate the fault point.When important data is missing or wrong,and the DG grid-connected line installed without measuring devices fails,according to the principle of network layering,the position of the fault point can be inferred by using other traveling wave head information.The PSCAD/EMTDC simulation results show that the method is accurate in positioning and has a high tolerance for traveling wave measurement information.关键词
