Implementation of a real time simulator for protective relay testing Calviño-Fraga, Jesús

Abstract

Details on the implementation of the Real-Time simulator for protective relay tester on an off-the-shelf hardware platform are presented. This simulator is a particular implementation of the OVNI simulator (Object Virtual Network Integrator) being developed at the Power System Simulation Laboratory of the University of British Columbia. This report includes the details on the implementation of fast and accurate models for current and coupling-capacitor voltage transformers. Also described are the details on the implementation of accurate timing and other operating system related issues. The user interface program, as well as details on the hardware/software implementation of the simulator are also presented.
