Plant operation optimization support device, plant operation optimization control device and method

A plant operation optimization control device for improving an efficiency of a plant operation, the plant operation optimization control device in communication with a processor, memory and storage, the plant operation optimization control device comprising:

• an input device that inputs an operation amount signal provided to a plant and a process signal detected by the plant as input signals;
• a sensitivity estimation device that requires a time-series change of the process signal as for the operation amount signal, as a sensitivity signal;
• a signal classification device that classifies an operation state of the plant from the input signals to provide an operation state signal and that extracts the sensitivity signal indicating a high sensitivity from the sensitivity signals in every classified operation state, as a state-classified high sensitivity signal;
• a control rule optimization device that, on receipt of the state-classified high sensitivity signal, determines an optimized control rule in a plant control for transition to a target state and provides the above as a control rule signal, when a high efficiency operation state of the plant is defined as the target state;
• a display device configured to present the control rule signal provided by the control rule optimization device and the operation state signal and the state-classified high sensitivity signal provided by the signal classification device as a displayed data;
• and
• a control device that determines the operation amount signal provided to the plant using the displayed data including the control rule signal obtained from the state-classified high sensitivity signal during a time of the operation state signal,
• wherein as a result of the operation amount signal obtained based upon the state-classified high sensitivity signal an amount of data from the input signals required for the determination of the operation amount signal is reduced, and
• the plant operation transitions to the target state based upon the optimized control rule.
