Improvements in protection and control via communications methods used to exchange digital bits (DBs) among devices are common in progressive utilities in high-voltage sub-stations. These improvements are now being incorporated into the process-sensitive electric power distribution systems of large industrial plants. Until now, new equipment purchases for new projects in industrial facilities using microprocessor (μP) multi-function protective relaying technology were typically done as a direct replacement of older technologies or as an updated equivalent. This paper describes a recently commissioned electrical substation design philosophy, including implementation, construction, maintenance, and performance with μP-based protective relaying, metering, and control schemes. These schemes extensively utilize the interdevice DB exchange and programmable logic capabilities of time-synchronized μP technology.
