Abstract
A thermal efficiency diagnostic of a combined power generation plant is performed by using measurement data relative to energy input/output of the respective equipment of the combined power generation plant, recording the design values of heat balance, using measurement data having high measuring accuracy as standard parameters, conducting an optimum state estimation by adjusting the key parameters, which largely affect the diagnostic results so as to be consistent with the standard parameters, so that each deviation of the reference parameters becomes minimum and the probability of the heat balance becomes maximum in a whole plant, comparing the heat balance thus determined with the heat balance based on a design value, analyzing the degree of contribution of performance of each equipment to the thermal efficiency and specifying the equipment which causes the thermal efficiency deterioration in accordance with the degree of contribution.
