Impact of MOV-Protected Thyristor Controlled Series Capacitor (TCSC) on Distance Relay Trip Boundaries in the Nigeria 330KV Power System

open access: yes, 2020
Metal-oxide-varistor (MOV) devices, connected in parallel have been used to protect the series compensation against overvoltage during faults. The MOV-protected series compensation increases the complexity of fault analysis and device protection. Hence the performance evaluation of distance protection scheme in the presence of Flexible Alternating ...
