Load management terminal
First Claim
1. A microprocessor based load management terminal, said load management terminal being a component in a power distribution system for delivering electrical power and carrying information, said load management terminal comprising:
- a power line coupling unit connecting said load management terminal to the power distribution system;
a signal receiver and conditioning unit producing a command signal in response to said power line coupling unit;
control logic means performing load management functions in response to said command signal;
a power supply producing supply voltages for said load management terminal;
a plurality of load control switches each selectably connecting a load to said power distribution system in response to said control logic means; and
a cold load pick-up monitoring one of said supply voltages, said cold load pick-up producing an output signal responsive to power outages, said output signal input to said control logic means such that said load is disconnected in response to said cold load pick-up;
said loads being disconnected by said control logic means in response to a said cold load pick-up output signal for a predetermined shed time plus a randomly generated shed time such that said loads are reconnected to the power distribution system at different times.

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.
