Abstract :
The new enhanced protection method dedicated for HV three-ended transmission lines is presented. Estimation of the fault location based on orthogonal components of voltages and currents calculated by use of developing window filters is discussed. The core contribution lies in introduction of variable reach characteristics of distance protection that are coordinated with proposed expanding data window filters. The performance of the scheme was tested with use of data obtained from EMTP-ATP simulations of faults in an HV test power network.
