Boiler-turbine dynamics in power-plant control

Fossil-fired power plants are generally equipped with complex control systems, the structure of which reflects the relevant process dynamics underlying the steam-generation process. This paper highlights the principal dynamic phenomena which determine the structuring of boiler-turbine control systems, clarifying the essential connections of such phenomena with the physical nature of the process. In this way, it also describes how to capture basic boiler dynamics by simple first-principle models, specifying the limits of their use for control design. Copyright (C) 1997 Elsevier Science Ltd.
