| Abstract: | When non -linear load transmission line appears fault,the conventional ways of faultlocation often occur big errors,it makes against the fault judgment. this study puts forward two -terminal fault location correcting algorithm for HV transmission line based on two-terminal nonsynchronous data correction from the filter algorithm analysis and line parameter on -linemeasurement. The simulation result shows that this algorithm is accurate,reliable and stable fordistance measuring,meet the need of field operation. |
