ABSTRACT:In this article an algorithm for transmission line fault location is discussed. This algorithm is based on Distributed Parameter Line Model which utilizes unsynchronized voltage and current measurements from two ends of the line. Firstly, the algorithm is derived, based on Distributed Parameter line model, then the simulation is carried out in MATLAB to obtain the fault voltages and currents at both ends of a transmission line. Then, with the help of Newton-Raphsonapproach based iterative method simulated data is used for estimating the location of faults (unbalanced and balanced) on line. It is observed that solution is independent of fault resistance and source impedance. Evaluation studies based on MATLAB/SIMULINK Simulation studies have been undertaken to verify the accuracy of the algorithm.

“…Accurate fault location in both cases of permanent and temporary faults is useful and can reduce the time and expenses of repairing the faulted line and would yield continuity of service [1]. Different methods have been presented so far for calculating the exact location of faults on transmission lines [2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Conventional methods [2-10] directly calculate the location of fault using the governing equations between voltages and currents based on the model they consider for the transmission line.…”

An accurate algorithm for locating faults on two-terminal transmission lines is presented in this study. The presented method does not require values of line parameters to locate the fault; therefore variation of line parameter values does not affect its accuracy. The method utilises synchronous post-fault measurements of currents and voltages in both terminals and is based on the distributed time-domain representation of transmission lines. Unlike conventional methods, fault location is converted to an optimisation problem. Then, this problem is solved by genetic algorithm to find the accurate location of fault. Furthermore, modifying the problem to be solved by the Newton optimisation method is discussed in this study. Simulation results performed by ATP/EMTP verify high accuracy of the presented method, and reveal that it is not significantly affected by fault resistance, fault type, fault inception angle and source impedance. Moreover, effect of measurement errors and synchronisation errors on the accuracy of presented method have been analysed which verify the efficiency of the algorithm in these conditions.
