摘要

This article describes the protection, control, and automation system developed for a distribution system consisting of 2 generators and 14 substations that are on 3 loops. This project updated the protection and control scheme and added Supervisory Control and Data Acquisition (SCADA) to the site. The design is based on installing multifunctional microprocessor relays at all remote sites and on the corresponding loop circuit breakers in the 13.8 kV switchgear at the Power Plant. Protection is accomplished using programmable functions in each relay and multicast Ethernet messages to mirror data from one relay to others at adjacent substations on each loop. SCADA is accomplished by directly accessing the Human Machine Interface (HMI) and software provided with the relays.
