Abstract

This paper presents implementation details describing a new design of a real-time digital simulator for relay testing. The simulator is developed under requirements to utilize, as much as possible, low cost commercial computer hardware and system software support. The other requirements ask for a three-terminal support with extensive graphical user interface (GUI) and a simulation time step as low as 50 μs. Such a design has been built for Western Area Power Administration (WAPA), USA, and fully validated using a model of an actual WAPA power system section. The simulator was delivered to WAPA in March 1994
