Research On Fault Location Algorithm For EHV Transmission Lines

With west-east and north-south electricity transmission, EHV transmission lines in a grid has been used. It is worth mentioning double transmission line on the same tower is narrow corridors, thus more and more widely used in the power system.Based on the analysis of the present fault location algorithms and the preliminary work of the students with the transposition of the transposed fault location algorithm. From the perspective of improving the theory and simulation of a double transmission line on the same tower untransposed line fault location algorithm. Bergeron line on the final wave propagation equations and mathematical morphology and the use of modern digital signal processing tools for single-line single-terminal fault location algorithm for a more thorough study again and based on the modified single-ended fault location time-domain algorithm.EMTP simulation: the algorithm is accuracy and validity, and the algorithm positioning accuracy, high precision, have some practical value.
