<p>PURPOSE: To provide a correlation diagram including ideal plant efficiency totally including even the time of bottom load or rated load even when a plant operating state shows an operation eccentric to the rated load. CONSTITUTION: Operation data inputted by a plant state input means 2 are preserved in a history data preserving device 4 and data required for providing the correlative relation of operation data are retrieved from this preserving device 4 and recorded in a retrieved result storage device 6. Besides, reference value data are inputted by an input means 7 and recorded in a reference value data storage device 8 corresponding to correlative relation display data recorded in this storage device 6. Corresponding to these recorded data, the reference value data are added to the retrieved result data, reference value curve data are prepared and these data are recorded in a storage device 10. Thus, while using the various data, a distribution diagram and a regression curve showing the correlative relation of operation data are displayed on a display device 12 by a reference curve display means 11.</p> |
