| Abstract: | This paper introduced correlation method to locate transmission line fault. First it described the principle of transmission line fault location based on traveling waves. The principle of correlation analysis is introduced, then the method using correlation analysis in fault location is given. Transmission line model is established with EMTP-ATP. Basing on the model, some kinds of fault are simulated. The feasibility of this algorithm is proved based on simulation results. By comparing with the classical wavelet analysis, this paper gave the advantages of this algorithm in two cases:noise influence suppression and accuracy of near distance fault location. Experiment is established to simulate transmission line grounding fault. The experiment result showed the correlation algorithm's validity . All the analysis result indicated that the correlation algorithm have a high precision. |
