Adaptive Regulation of the Boiler-Turbine Unit of a Combined Heat and Power (CHP)System

摘要

A simplified nonlinear model of a Combined Heat and Power (CHP) system is used toinvestigate the steady state errors, hunting phenomena and high interactions produced in the linear regulators currently employed in industry. In order to improve the regulation of the boiler turbine unit of the CHP system the gains of regulators should be changed adaptively according to the steam flow and valve position ratios and identical and fast acting servomotors should be chosen for the inlet and pass out values.
