The Impact

On EHV transmission lines, the impact of distributed capacitance is necessary to be considered in case of fault location. A novel fault location method for single-phase grounded fault of transmission lines is presented based on the distributed parameter model of transmission line. In this method only the voltage and current of single end is used. The residual phase voltage at the fault point should have the same phase angle as the current through fault branch due to the pure resistive characteristics of the fault path impedance. By virtue of searching the minimum phase angle differ-ence between the phase voltage along the transmission line and the fault-component current meas-ured at the side equipped with protection, the fault distance can be located. ATP simulations are used to generate data that are supplied as inputs to the fault location algorithm.
