PLANT CONTROL SYSTEM AND THERMAL POWER PLANT CONTROL SYSTEM

摘要

A control system for a plant acquires measurement data of a status quantity of the plant and calculates an operation signal to control the plant by using the measurement data, characterized in that the control system comprising: a measurement data database to acquire and store a measurement data of a status quantity of a plant; a model constructing database to store a model constructing data obtained from conversion of measured data of the plant stored in the measurement data database; a statistical model to simulate plant control characteristics from which a value of the measurement data, which is a status quantity of the plant, is inferred by using the model constructing data stored in the model constructing database when a control signal is given to the plant; an operation method learning part to learn a method of generating a model input equivalent to the control signal given to the plant by using the statistical model so that a model output equivalent to the measurement data achieves a target value; a learning information database to store a constraint condition for learning by the operation method learning part and learning information data about a learning resu and a control signal generating part to calculate a control signal to be sent to the plant by using the measurement data in the measurement database and the learning information data in the learning information database; and a model adjusting part to adjust a basis radius parameter of the statistical model included in the model constructing data to be stored in the model constructing database, whereby the statistical model generates the model output by using adjustment result of the basis radius parameter obtained from the model adjusting part.
