SYSTEM AND ASSOCIATED METHOD FOR MONITORING AND CONTROLLING A POWER PLANT

摘要

A control system, for use with a power plant having a mill for pulverising material for input into a combustion system of the power plant, the control system comprising: a first sensor (12), for recording a first parameter of a first output from the combustion system; a second sensor (14), for recording a second parameter of a second output from the combustion system; an adjuster system (16), for adjusting and recording at least one variable parameter of the combustion system; a state estimator (18) component operable to receive a first signal relating to such first parameter, a second signal relating to such a second parameter and a third signal relating to such at least one variable system parameter, the state estimator component being operable to use the first signal, second signal and third signal to produce a material parameter indicator signal (20) and a system state indicator signal (22); and an output component (24) operable to receive such a material parameter indicator signal and such a system state indicator signal and to combine said material parameter indicator signal and system state indicator signal to produce an output control signal.
