Series-compensated transmission lines (SCTLs) are increasingly preferred for transmitting bulk amounts of electricity generated from the present-day large-scale wind farm to utility grid due several technical and economic benefits. However, when a fault occurs in such farm-integrated SCTL, impedance across metal oxide varistor (MOV)-protected series capacitor varies non-linearly. Also, current ...

This paper proposes an adaptive dynamic Mho distance relay based on a phase comparator scheme for protecting interconnected transmission networks compensated with Thyristor Controlled Series Capacitor (TCSC). The proposed uses impedance index factor to initiate the fault detection subroutine. RMS of positive sequence current faulted loop and TCSC terminal are compared zone identification. A gro...
