Abstract
In this paper, the parameters of Rowen’s model for heavy duty gas turbines in dynamic studies are estimated by use of available operational and performance data. The transfer function model of heavy duty gas turbine is required for the analysis and development of optimal controllers. The speedtronic controller derived from Rowen’s model has three controller namely, speed, acceleration and temperature. The model with all these controllers is developed with MATLAB/Simulink to study their response and arrive at the simplified model. The speed controller may have isochronous or drooping governor characteristics. The choice of governor characteristics for the simplified model is made from the response of the system simulated for an unit step load disturbance. The equations are to be validated with the response of the system simulated using MATLAB/Simulink.
