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.
