This paper describes a new algorithm for selection of faulty circuit in parallel series-compensated lines. It suits for protection of such lines and uses one-end phase currents measurements only. The developed method has been tested and evaluated using signals obtained from versatile computer simulations. A detailed models of considered transmission line including the SC&MOV banks as well as the...
An accurate algorithm for locating faults on a series-compensated line is presented. This algorithm can be applied with current differential protective relays since two-end currents and one-end voltage are utilized as the fault locator input signals. The algorithm applies two subroutines and the procedure for indicating the valid subroutine. The algorithm has been evaluated using the fault data of...
This paper presents an accurate algorithm for locating faults on a series-compensated line. It applies two-end currents and one-end voltage and thus can be applied with current differential protective relays. The algorithm applies two subroutines and the procedure for selecting the valid subroutine. The algorithm has been evaluated using the fault data of ATP-EMTP versatile simulations of faults on...
This paper presents an accurate fault location algorithm for double-circuit series compensated lines. Use of two-end current and voltage signals with taken into account a more general case of unsynchronized measurements is studied. Different options for analytical synchronization of the measurements are considered. The algorithm applies two subroutines, designated for locating faults on particular...
