The potential of icon-based simulation tools has only recently been fully appreciated and is now being exploited for the simulation of large-scale systems. Modern advanced simulation tools enable such systems to be rapidly analysed, aiding both the design process and the task of identifying improvements to existing systems. Modelling and Simulation of Power Generation Plants reports on the research at the Industrial Control Centre, University of Strathclyde, in using such tools to establish a simulation library for power generation plants. The authors present the complete development of the simulation library from modelling to algorithm construction and simulation. The material is set in the general context of control strategies for combined cycle/combined heat and power configurations.
