并已应用于多台超临界600MW火电机组。
Abstract
On the basis of simplified model of a supercritical 600 MW unit
simulation on current three coal quality correction schemes was conducted.Moreover
the simulation results were compared with the actual curves to analyze the advantages and disadvantages of each correction scheme and the control indices
thus to propose a coal quality adaptive correction scheme with excellent performance.The new scheme efficiently enhanced the response speed and accuracy of the unit coordinated control system on the coal quality
and has been successfully applied in multiple supercritical 600MW units.
