PLANT OPERATION SUPPORT DEVICE

PROBLEM TO BE SOLVED: To provide a plant operation support device allowing adjustment in consideration of balance of the whole plant even if a parameter is a parameter affecting a dynamic characteristic. SOLUTION: This plant operation support device using an online simulator has: a tracking model part generating a tracking model while online performing the parameter adjustment based on actually measured data of the actual plant; a prediction model part generating prediction data based on the tracking model; and a prediction/actually measured data storage part storing the generated prediction data and the actually measured data. The tracking model part adjusts the parameter such that a difference between the prediction data and the actually measured data stored in the prediction/actually measured data storage part becomes minimum, and updates the tracking model.
