摘要

The conventional distance relays exhibit limited performance while used for the protection of unified power flow controller (UPFC) compensated transmission lines (TLs) due to rapid changes of voltage and current signals during various operational modes of UPFC. This paper investigates the impact of the different operating modes of UPFC and propose an improved protection algorithm for the relay. Th...
