THE USE OF THE ÅSTRÖM-BELL MODEL FOR THE DESIGN OF DRUM LEVEL CONTROLLERS IN POWER PLANT BOILERS

Abstract This paper is concerned with the study of drum water level control using the well established single element and 3 element controllers. The study is based on the Astrom-Bell (A-B) interpretation model of the boiler, which is used to simulate a 160 MW plant P16-G16 in Sweden and a 500 MW plant WW500 in Australia.
