Abstract
High voltage transmission line is the main channel of transmitting electricity, and the operation reliability is closely related to power effective transmission. In this paper, by analyzing advantages and disadvantages of traveling wave method, transmission line fault location technology based on the OPGW cable was proposed. Basic principle and advantages of this fault location technology were introduced. Three-phase overhead lines fault model was constructed based on PSCAD. Through simulations under different fault types in different fault points, the transient process of the fault phase voltage waveform was analyzed in detail and the fault point was located using the wave pattern features. By comparison, the simulation results and the actual location of fault point were in good agreement, which proved the feasibility of this fault location method.
