Energy conservation control method |
摘要 |
An energy conservation schedule is followed automatically in response to production activity in a plant facility. The demand of power from the utility company is used as an indicator of actual production activity. The ON/OFF ratio of non-production loads is reduced to conserve energy and such adjustment is automatic in relation to actual demand of power. In one embodiment of the invention, a higher level of constraint is imposed on the non-production loads as soon as the demand has passed a critical threshold downward. In a second embodiment of the invention, control of the demand is installed in the plant in order to meet a demand limit at the end of a period of control involving the production loads as well as non-production loads under constraints. In the latter situation, whenever demand control is ineffective for a full control period to affect switching of the production loads, the system goes to energy conservation with a higher level of constraints applied to the non-production loads.
