Determining Parameters of Turbine´s Model Using Heat Balance Data of Steam Power Unit for Educational Purposes

In this paper, the procedure for deriving the parameters of an IEEE governor-turbine model (particularly turbine model) based on a practical study case consisting of a 200-MW tandem compound, single reheat steam unit and its available heat balance data is presented. The main focus of the work is on presenting a regular procedure and using only available heat balance data of the steam unit, to be suitable for training the principles and details of such an approach for educational purposes. Unavailable parameters are approximated with simple thermodynamic assumptions, resulting in good correspondence to typical values. The model response to step changes for special scenarios is simulated and presented as well.
