Abstract

In terms of power frequency component of two terminals fault location principle, there are some traditional problems,such as the synchronization difficulty on the measured data between two ends of line, the more iterative times, the slower convergence speed and the difficulty of identifying the false roots. Thus, the paper proposed a new fast fault location method based on voltage distribution regularities along transmission line. The paper analyzed the distribution of voltage amplitude along transmission line on the basis of distributed parameter line model. A transmission line is divided into several areas according to the monotonicity of voltage amplitude distribution curve under an internal fault. The tangent line can be gotten by two distributed points in each area, and the fault location can be preliminarily determined based on the tangent intersection principle. Considering the fault location error caused by the nonlinear factors of long line parameter, the tangent intersection principle is further used to adjust the location results iteratively until the fault distance successively approximate to the actual fault point. Simulation results show that the proposed fast fault location method only uses the line parameters and the measured data at the single terminal, so the method can accurately remove the false roots and achieve precision location results based on several iterations without the synchronization of the data. Also it shows that the principle of fault location is simple, the number of iterations is small, and the convergence speed is fast. The fault location can be locked within 300 meters only by the calculation of 4 times.

Key words： Transmission line fault location voltage distribution tangent intersection iteration
