Simulation Results

Lightning overvoltage often leads to transmission lines trip, which is the weak link of power system. In this paper, 110-kV transmission line model is studied on the basis of the EMTP software. Several simulation models are established for back flashover lightning, induced lightning, shield failure. The transient process of lightning stroke is studied. According to the contrast of simulation results of three kinds of lightning, a set of discriminant basis to distinguish lightning on transmission line is put forward.
