Abstract
A load management terminal is utilized as an end device in a utility's distribution network communication system. The distribution network carries electrical power as well as communication signals. The load management terminal is comprised of a power line coupling unit for connecting the load management terminal to the power distribution network. A signal receiver and conditioning unit produces a command signal in response to a received communication signal. A solid state memory contains preprogrammed instructions and data. A control logic circuit performs load control functions in response to the preprogrammed instructions, data and the command signal. These load control functions include the opening and closing of load control switches for selectively disconnecting and connecting, respectively, customer loads. A cold load pick-up produces power outage information enabling the load management terminal to provide local, load control functions.
