Plant control apparatus

A plant control apparatus having operation signal generating unit for calculating an operation signal to be supplied to a plant by using a measurement signal representative of a running state amount of the plant, comprising:

• numerical value analysis executing unit for calculating a numerical value representative of characteristics of the plant;
• learning unit for learning for learning a method of generating the operation signal to make the plant have a desired running state, by using a model configured in accordance with a numerical value analysis result by said numerical value analysis executing unit;
• and
• analyzing unit for analyzing an effect of changing the operation signal in accordance with a learning result, in accordance with said numerical value.

A control apparatus for a plant having a boiler comprising:

• stream line data calculating unit for learning a relation between input data and output data by using a numerical analysis result including at least a gas flow phenomenon occurring in the boiler, and by using, as the input data, at least a fuel flow rate and an air flow rate supplied to burners and an air flow rate supplied to air supply ports other than the burners, and by using, as the output data, position data of a stream line representing a locus of a gas flow supplied from said burners and said air supply ports;
• stream line drawing unit for receiving the stream line position data output from said stream line data calculating unit, and executing a calculation process for drawing the stream line on a display screen as an image;
• and
• image displaying unit for displaying the stream line of gas supplied from said burners and said air supply ports and visualized by said stream line drawing unit.

An operator training apparatus for a plant having a boiler, comprising:

• phenomenon visualizing unit for visualizing a phenomenon in the boiler to display a relation between a control operation and the phenomenon in the boiler;
• and image display unit for the relation visualized by said phenomenon visualizing unit on a screen,
• wherein said phenomenon visualizing unit comprises:
• stream line data calculating unit for learning a relation between input data and output data by using a numerical analysis result including at least a gas flow phenomenon occurring in the boiler, and by using, as the input data, at least a fuel flow rate and an air flow rate supplied to burners and an air flow rate supplied to air supply ports other than the burners, and by using, as the output data, position data of a stream line representing a locus of a gas flow supplied from said burners and said air supply ports;
• stream line drawing unit for receiving the stream line position data output from said stream line data calculating unit, and executing a calculation process for drawing the stream line on a display screen as an image;
• and image displaying unit for displaying the stream line of gas supplied from said burners and said air supply ports and visualized by said stream line drawing unit, and wherein a stream line of the gas supplied from said burners and said air supply ports and visualized by said stream line drawing unit is displayed on the screen of said image displaying unit.
