OPERATION CONTROL SYSTEM OF CIRCULATING FLUIDIZED BED BOILER

摘要

DISCLOSED IS AN OPERATION CONTROL SYSTEM (21) OF A CIRCULATING FLUIDIZED BED BOILER WHICH CAN PERFORM CONTROL FOR OPTIMIZING A PLURALITY OF INDEX ITEMS OF THE CIRCULATING FLUIDIZED BED BOILER BY A PLURALITY OF SETTING ITEMS. THIS OPERATION CONTROL SYSTEM INCLUDES A BOILER CONTROLLER (27) WHICH PERFORM OPERATION OF THE BOILER (2) WITH AN OPERATION AMOUNT (MV) DETERMINED BASED ON COMPARISON BETWEEN THE INPUT VALUES (SV3) OF A PLURALITY OF SETTING ITEMS AND THE ACTUAL MEASUREMENT VALUES OF A PLURALITY OF INDEX ITEMS; A BAYESIAN NETWORK INFERENCE UNIT (39) WHICH SELECTS SOME OF A PLURALITY OF SETTING ITEMS AND CALCULATES ADJUSTMENT VALUES (SV2) FOR ADJUSTING THE INPUT VALUES (SV1) OF SELECTED SETTING ITEMS, AND AN INPUT VALUE ADJUSTMENT UNIT (51) WHICH TRANSFERS ADJUSTED INPUT VALUES, WHICH ARE A FUNCTION OF THE OPERATOR INPUT VALUES (SV1) TO BE VALUES INPUT BY AN OPERATOR AND THE ADJUSTMENT VALUES (SV2), TO THE BOILER CONTROLLER (27) AS THE INPUT VALUES (SV3) OF THE SELECTED SETTING ITEMS. THE BAYESIAN NETWORK INFERENCE UNIT (39) PERFORMS CALCULATION USING A BAYESIAN NETWORK TO CALCULATE THE ADJUSTMENT VALUES (SV2). THE MOST ILLUSTRATIVE DRAWING IS FIG.2.
