Power plant performance evaluation method and power plant performance evaluation program

摘要

The object of the present invention is to provide a power plant plant evaluation method capable of determining the performance fluctuation of the power plant.The power plant performance evaluation method of the present invention isObtaining a plurality of operation data and external factor variation data per unit time representing a predetermined reference period of the power plant and an evaluation period after the elapse of this period, and obtaining the external factor fluctuation dataAmong multiple operation data acquired in the standard periodAt least one operation data with constant correlation with external factor fluctuation data is selected as the target operation data.The correlation function between the target operation data and the external factor data is obtained.On the operation data corresponding to the external factor fluctuation data acquired in the evaluation periodDeriving alternative operation data based on the correlation function andComparing this alternative driving data with actual operating data acquired during the evaluation period, andIs included.Diagram
