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...

Photovoltaic (PV) power plants have comparatively weak infeed characteristics, unlike conventional synchronous generators. The controllability of grid-connected inverters and the limited overcurrent capability electronic devices means that characteristics faults on transmission lines fed by PV stations are substantially different than those sources. Operating performances distance relays PV-fed...

Conventional distance protection methods usually require additional filtering of the input signals to remove influence DC component and distortion sinusoidal signals. The paper shows an algorithm that does not proposed uses measured voltages at beginning line auxiliary as were calculated from currents known parameters. compares instantaneous values detects a fault on based change in phase angle...
