Title:
CONTROLLING METHOD FOR OPTIMUM EFFICIENCY OF THERMAL POWER PLANT
Document Type and Number:
Japanese Patent JPS5843002
Kind Code:
A
Abstract:
PURPOSE:To always keep the plant efficiency at the highest level, by deciding plural initial point groups in consideration of the plant efficiency characteristics obtained previously and the limit conditions of the state of plant. CONSTITUTION:A calculation is carried out for estimation of the model normative efficiency by means of a plant model 240 for calculation of efficiency which is incorporated in a control system 200. A maximum efficiency searching means 230 delivers the trial operation quantity 9 to the model 240 before deciding the optimum operation quantity 11. Thus the plant efficiency 10 is obtained. The above-mentioned procedure is repeated to search the maximum efficiency point. In this case, the initial trial point group is decided by means of the model 240 in consideration of the plant efficiency characteristics obtained previously and the limit conditions of the state of plant.
