Digital protection relays are of interest to electric utilities because of their unique data acquisition and communication capabilities. A functional specification for a high-speed digital relay for transmission line protection has been developed, along with its hardware and software architecture and design. The project team developed a product specification based on application and utility market requirements. They followed this effort with an algorithm section process that involved study and computer simulation tests and evaluation of candidate algorithms. The final steps involved hardware and software design. The results of phase 1 hardware and software design indicated that a reliable, cost-effective digital line protection relay could be developed. The phase 1 effort was completed in July 1989 and is described in this report. Subsequent to this work, General Electric Company, on its own, conducted detailed hardware design, software integration, testing product prototyping, and design optimization and developed peripheral support software as well as manufacturing and test facilities. The resulting product has achieved broad acceptance by utilities. 6 figs., 5 tabs.
