Abstract

This paper reports on power transmission distance relay application testing using simulated transient waveforms. Power system modeling and test procedures using modern digital simulators are presented. An extensive study of five commercial relays, comparing their application for a 345 kV transmission line, is carried out by performing thousands of one-terminal and synchronized two-terminal transient tests. The digital simulation approach has proved to be an efficient technique. This paper presents a methodology for evaluating distance relay transient performance based on extensive laboratory testing. Important issues regarding application testing are also addressed and investigated in this paper
