After a Major Automation Rollout, the Benefits Roll In: JEA leverages a distribution automation system to maintain voltage quality and reduce system load

摘要

In 1999, JEA initiated a distribution automation (DA) program, focusing on its 26-kV distribution system for voltage control, fault isolation and service restoration. JEA (Jacksonville, Florida, U.S.) installed some 200 remotely monitored and controlled feeder reclosers in 90 26-kV feeders, and 88 DA-ready LTC voltage controllers at the substations. The utility also installed a package of DA software applications on computers in the control center for performing three major functions: distribution operation modeling and analysis (DOMA), volt-VAR optimization (VVO), and fault location, isolation and service restoration (FLIR).
