PLANT OPTIMUM-OPERATION CONTROL SYSTEM

摘要

Disclosed is a plant optimum-operation control system capable of minimizing an operation cost while keeping the operation of a plant stable.  The plant optimum-operation control system comprises an optimum operation-point calculating means (3) for calculating an optimum operation-point to minimize the operation cost of a non-utility generation plant (20), an automatic control means (9) for automatically controlling the plant on the basis of an optimization model in accordance with the optimum operation-point determined by the calculation of the optimum operation-point calculating means, an automatic control making means (5) for starting the automatically controlled operation of the non-utility generation plant by the automatic control means in response to an input, and an optimization variable selecting means (6) for selecting the variable of an optimization subject of the non-utility generation plant in the optimization model, when the automatic control making means performs the automatic control operation.
