The Athens Automation and Control Experiment (AACE), a large-scale distribution automation research project, was conducted at Athens, Tennessee. The experiment involved the monitoring and control of three substations and twelve feeders (nearly the entire system) of the Athens Utilities Board (AUB). The monitoring and control hardware consists of supervisory and data acquisition, feeder monitoring and control, and customer load control. In total 75 locations on the AUB distribution system were automated and 2000 customer loads were placed under control. The controlled equipment includes 2 load-tap-changing transformers, 12 circuit breakers, 4 line regulators, 29 capacitor banks, 35 load break switches, 12 power reclosers, and 21 fault detectors. Two software programs, an automated capacitor control program and distribution automation analysis program, that have been essential to the AACE are discussed. There have been several operational benefits associated with the automation of the AUB system which are described in this paper. 10 refs., 10 figs., 1 tab.
