<P>PROBLEM TO BE SOLVED: To provide a power control apparatus for numerically grasping the effect of demand control. <P>SOLUTION: A power control apparatus 1 is connected to each of a power apparatus 2 and forcedly shuts off the operation of the power apparatus 2 to realize the demand control. It comprises main processes (ST1-ST9) which are repeatedly performed, after a power is turned on as an infinity loop, and timer interruption processes (ST20-ST28) started at regular time intervals. The timer interruption processes include a first process ST21 which detects an instantaneous current supplied to the power apparatus, a second process ST23 which cumulatively counts the number of times if significant values are detected in the first process, and third processes ST26 and ST27 which cumulatively count frequency of no significant power detection in the first process, depending whether it is on forced shut off. <P>COPYRIGHT: (C)2003,JPO |
