Digital simulator activity within IEEE Power Systems Relaying Committee

This paper summarizes activities of two working groups formed within the IEEE Power Systems Relaying Committee to deal with issues related to the digital simulators for protective relay testing. Working Group F-8 is concerned with digital simulator performatiice requirements for relay testing while the Working Group F-10 investigates digital models for voltage and current transformers. Since the activities of both working groups are still in progress, this paper gives outlines of the working group assignments and examples of soine preliminary results presently discussed by tlie working group members. The final reports of both working groups are expected in late 1996, early 1997 time frame.
