Abstract:   (2760 Views)
In this paper, a new algorithm has been proposed for determining accurate fault distance on multi-terminal transmission lines. This method is based on genetic algorithm, and uses synchronous data recorded at all terminals, and includes two steps. In the first step, employing a comparing method, the faulty section is identified. In the second step, precise distance of the fault is found utilizing genetic algorithm. This method is more accurate compared to the previously proposed algorithms for multi-terminal transmission lines, Since it utilizes the distributed parameter line model in the time domain which fully models the capacitive characteristic of the line, and also because of employing the recorded samples at the terminals, presented harmonics in the waveforms of the terminals do not influence on the performance of the algorithm. Simulation results show high accuracy of the proposed method compared to the previously algorithms.
