A simplified nonlinear model for a Combined Heat and Power (CHP) system
Abstract
Steady state errors, hunting, and high interactions were reported in the operation of Combined Heat and Power (CHP) systems working with steam turbines. The design of currently employed regulators in industry is usually based on a linear model of the system. An improved system regulation can only be achieved if a more accurate mathematical model is available. A simplified nonlinear model is derived which can be used to investigate the present problems and evaluate new controller performances.
