Water demand optimization system, control system and program

摘要

According to one embodiment, a water demand optimization system includes a management terminal, a measuring apparatus, a demand information generating unit and a water-supply control apparatus. The management terminal drives customer equipment, which performs an operation using water, in a time zone in which a power unit rate is low. The measuring apparatus measures an amount of water used in a dwelling unit. The demand information generating unit generates water demand based on the amount of water. The water-supply control apparatus controls a pump in a manner to meet water demand and to minimize a treatment cost in a water purification plant and a cost for conveyance of clear water with reference to a variation in the power unit rate.

主权项

1. A water demand optimization system which conveys clear water from a water purification plant to a distributing reservoir by a pump, and supplies the clear water pooled in the distributing reservoir to an urban area including a plurality of dwelling units, the water demand optimization system comprising:
a management terminal provided in each of the plurality of dwelling units, and configured to drive customer equipment, which performs an operation using water, in a time zone in which a power unit rate is low in each of the plurality of dwelling units; a measuring apparatus provided in each of the plurality of dwelling units, and configured to measure an amount of water used in the dwelling unit in which the measuring apparatus is provided; a demand information generating unit configured to generate water demand information in the urban area, based on the amount of water measured by the measuring apparatus provided in each of the plurality of dwelling units; and a water-supply control apparatus configured to set an impoundment ratio of the distributing reservoir based on water demand indicated in the water demand information and a power unit rate, and to control the pump to convey the clear water in an amount satisfying the set impoundment ratio to the distributing reservoir in a time zone in which the power unit rate is low.
