<p>PROBLEM TO BE SOLVED: To provide a power usage control system which allows for usage of maximum power, while controlling so that the power usage goes below a use limit amount during power usage limitation.SOLUTION: A power usage control system 1 comprises: a total load measurement section 5 for measuring the total load in a power line 3 on the power demand side; m (m is a natural number) switches 8a capable of switching interruption and introduction of power from the power line 3 to a branch line 3a individually; a calculation section 36 which transmits an interruption signal n(where 1≤n<m, n is a natural number) when a total load data 30 goes above a use limit amount data 26, and transmits an introduction signal n when the total load data 30 goes below introduction reference n data 36; and an output display section 10 which can display the electrification situation of m switches 8a. When an interruption signal n or an introduction signal n are transmitted from the calculation section, a switch corresponding to the interruption signal n or an introduction signal n is switched.</p> |
