Operating condition evaluation device, operating condition evaluation method and control system for power plant

摘要

Provided is an operating state evaluation device for evaluating an operating state of a power plant, which is configured to include: an operating mode input section for receiving an operating mode input of the power plant, a behavior model storage section for storing behavior models indicating virtual behavior of the power plant, a simulation section for applying the operating conditions to the behavior models and for calculating virtual process values of the power plant, the operating states containing a set of operating parameters which is set to each of a plurality of manipulation ends provided with the power plant, a storage section for weighted coefficients for storing a weighted coefficient which is defined according to the operating mode for each of the virtual process values and an evaluation calculation section for determining the weighted coefficient corresponding to the input operation mode with Reference to the memory section for weighted coefficients and for calculating an evaluation result of the operating states in each case on the basis of a value which is obtained by multiplying the virtual process values by the weighted coefficient.
