This article discusses the work carried out in the development, validation and verification of the Turbine/Governor model (GGOV1) in GE Control Systems Toolbox to comprehend the impact of Turbine controls post system transient. Simulation related studies are carried out using the model developed. MATLAB /Simulink has been used as the platform for validating the model. The validated model is replicated in the GE Control System Toolbox , for enhanced grid Simulation related studies. Comparative analysis of results obtained in both platforms with the validated parameters has been accomplished.
