Abstract: The pulse closing technology can avoid thermal stress and mechanical stress caused by medium-voltage or high-voltage (more than 10 kV) faulty lines reclosing. Aiming at the characteristic that the pulse closing technology needs to deal with a large amount of historical fault data, carrying out fault analysis slowly, this paper adopted Monte Carlo algorithm to make the current pulse clipped and analyzed quickly and accurately. WAVEWIN software was used to derive and analyze fault waveforms, to make the equipment response quickly, which removes the power network faults, so as to ensure the normal operation of the distribution system.
Key words: Monte Carlo algorithm; pulse closing technology; recloser
