ENERGY MONITOR CONTROL PROCESS, ENERGY MONITOR CONTROL SYSTEM AND ENERGY MONITOR CONTROLLER

摘要

PROBLEM TO BE SOLVED: To improve the accuracy of demand control for contract demand power in an energy monitor control process, energy monitor control, and energy monitor controller for performing measurement monitor and demand control for the power usage of a load such as electrical equipment installed at a plant or the like.;SOLUTION: A measuring function unit 3 measures the electrical energy consumption of a plurality of loads 7, 7, respectively, and a demand control function unit 2 predicts a used electrical energy amount upon the end of a time limit from the electrical energy consumption at predetermined time intervals from the start of the time limit and the respectively measured present electrical energy consumption of the plurality of loads. At least one of the plurality of the loads 7, 7 is controlled so that predicted electrical energy is within a predetermined contract value. By this constitution, a demand controller and a measuring apparatus are individually operated, and the demand controller predicts demand power from a tendency value of a measured pulse from WHM, thus solving problems such as low precision in demand control due to asynchronous operation in time between the prediction and load control.;COPYRIGHT: (C)2005,JPO&NCIPI
