this paper investigates the islands formation in initial stages of restoration process in blackout condition and studies the impacts of islands number variation on the process execution. in addition, a method is proposed to determining each island optimal boundaries. then the effects of transmission lines thyistor controlled series compensators (tcsc) to facilitate restoration process and impro...

This paper presents the impact study of GTO Controlled Series Capacitor (GCSC) parameters on measured impedance (Zseen) by MHO distance relays for single transmission line high voltage 220 kV in the presence of single phase to earth fault with fault resistance (RF). The study deals with a 220 kV single electrical transmission line of Eastern Algerian transmission networks at Group Sonelgaz (Alg...

This paper presents a comprehensive survey on transmission and distribution fault location algorithms that utilize synchronized measurements. Algorithms based on two-end synchronized measurements and fault location algorithms on three-terminal and multiterminal lines are reviewed. Series capacitors equipped with metal oxide varistors (MOVs), when set on a transmission line, create certain probl...

In power systems, it is challenging to identify the faulty line and fault distance when compensating devices are present in system. This work presents a locator using an Adaptive-Network-based Fuzzy Inference System (ANFIS) that accurately estimates location on compensated conjunction with active differential-based backup protection algorithm for identification. Both identification ANFIS-based ...

An algorithm for locating faults on series-compensated transmission lines is presented. Use of two-end synchronized measurements of currents accomplished by current differential protective relays with additional incorporation of the locally measured three-phase voltage is considered. In case of double-circuit lines also providing of zero-sequence currents from the healthy parallel line is assum...
