Abstract

EHV/UHV long transmission lines have large distributed capacitance which has significant effect on the operation of a distance relay. To set the distance relay without considering the distributed capacitance will cause serious over reaching or under reaching. This paper analyzes the effect of distributed capacitance on the relay tripping characteristics and the setting principal of distance relay for EHV/UHV long transmission line is discussed.
Key words: EHV/UHV long transmission line, distance relay, distributed capacitance, relay tripping characteristics.
