| Abstract: | The methods of researching on no-direct-ground system are summarized and analyzed. That the numerical simulation method is the effective complementarity for analytic method and experiment is pointed out.A no-direct-ground-system simulation model is built up based on MATLAB. The simulation results are in accordance with the fact.Based on the simulation results,the characteristics of the single-line-to-earth fault is found directly,which are the base for line selecting algorithm.The simulation case shows the efficiency and the feasibility of the proposed method. |
