Gas turbines play an important role in power generation and aeroengines. An extended survey of methods associated with the control and systems identification in these engines, Dynamic Modelling of Gas Turbines reviews current methods and presents a number of new perspectives. • Describes a total modelling and identification program for various classes of aeroengine, allowing you . The Steam Turbine and Governor block implements a complete tandem-compound steam prime mover, including a speed governing system, a four-stage steam turbine, and a shaft with up to four masses. The speed governing system consists of a proportional regulator, a speed relay, and a servomotor controlling the gate opening. The objective of controlling a steam turbine is to extract the required amount of work from the turbine using the minimum amount of steam. The objective of the Process Control Engineer is to maximize the pressure in the steam chest at P will always result in minimizing the steam consumption per unit of work extracted in the turbine case.

The simulations indicate that the present control system design is capable of handling expected load transients satisfactorily. The dynamic characteristics of the experiment were investigated to determine specific control system designs required to satisfy varying electrical and waste heat demands and, at the same time, to keep plant component temperatures and stresses within acceptable limits.
