Comparison of Accuracy of various Impedance Based Fault Location Algorithms on Power Transmission Line

Ankamma Rao J ^[2] | Gebreegziabher Hagos

Abstract: Transmission line protection is important issue in power engineering because 85-87 % of power system faults are occurring in transmission lines. This paper presents three developed algorithms Takagis method, Ericsson method, Fault sequence component of current method. MATLAB/ Simulink software was used to implement these algorithms. The accuracy of fault location on power transmission line are compared for these three method by varying various parameters like fault type, fault resistance, fault location and fault inception angle, on a given power system model. The simulation results demonstrate the validity of the suitable fault location method in 400KV transmission line.
