Parameter Estimation and Dynamic Simulation Of Gas Turbine Model In Combined Cycle Power Plants Based On Actual Operational Data

Gas turbines are very important nowadays for electric power generation specially that used in the Combined Cycle Power Plants (CCPPs). For this electric power generation, the dynamics of the gas turbine and parameters estimation are very essential. In this article, a simple procedure is used for estimating the parameters of Rowen’s model for HDGTs in dynamic studies for analysis purposes. The parameters of Rowen's model for a 265MW HDGT are derived and several simulated tests using Matlab/Simulink are presented. The way of obtaining the parameters are based on simple physical laws. It explains briefly how to extract the parameters of the model using the operational and performance data. The obtained results via simulations using Matlab/Simulink are highly matched with the involved scientific articles that published in different literature. Furthermore, the obtained results verifies the operational results of the considered HDGT. However, the procedure here is applied on a practical HDGT. The same procedure could be applied for any scale (size) of gas turbines. [H. Emam Shalan, M. A. Moustafa Hassan, A. B. G. Bahgat.
