POWER MONITORING AND LOAD SHEDDING SYSTEM

摘要

An electrical power controlling/load shedding system includes power consumption metering and meter interfacing circuitry for entering overall power consumption into a central processing unit. The CPU memory includes a data storage table characterizing each system electrical load under each of a hierarchy of operational levels, and circuitry is provided for turning local and remote loads on/off, responsive to CPU-issued commands. The digital computing apparatus operates on the meter supplied information and projects energy consumption over the monitoring interval. If power must be shed to obviate an excessive projected demand, loads are examined seriatim and selectively shed on a priority basis as required, depending upon the operational parameters and status characterizing each load for the then prevailing load level condition.
