点击翻译按钮获取中文摘要

RTDS Technologies, Winnipeg is one of the leading organizations in the world developing real time digital power systems simulators. It offers detailed electromagnetic simulation modeling platform for testing protection systems, which is a core expertise area of the principal investigator. The company has a major R&D arm. The company has expressed keen interest in collaborating with Prof. Rama Gokaraju (University of Saskatchewan) and supporting a NSERC Engage grant proposal to develop and test a high speed digital protection system for extra voltage transmission systems. The research and development for this project would involve designing sub cycle Fourier transform method (using "phaselets") on latest digital hardware (field programmable gate array boards -- FPGAs), which are available in the computer industry. A state-of-the-art testing method used in the electric power industry would be adopted for testing the relaying functions. The hardware-in-the-loop testing platform would consist of the RTDS simulator with substation standard communication protocols -- "IEC 61850" (available at the University of Saskatchewan) and Xilinx ML-605 FPGA board. The testing platform would be used for evaluating the performance of the new digital relay similar to what is done in the industry. The findings of the testing would be useful for RTDS Technologies to demonstrate new relay testing methods to the developers, protection equipment manufacturers and the electric utilities. The results would published as an IEEE paper. The proposed research will provide a unique opportunity to the students to do both research and testing using the latest simulation and digital technologies available in the power industry.
