Hello, does anyone know what is the suitable speed governor GAST2A or GGOV1 for a gas turbine, for simulation with PSSE? Thank you.

The GAST2A model was developed in the 1980’s to represent old GE turbine controls (MKII to MKIV). Since that time, the turbine controls have evolved to include a governor with a proportional-integral controller and droop developed with electrical power as the feedback signal. Also, significant changes have been made to the gas turbine design to improve performance. The GAST2A model is not recommended for use for modern gas turbine installations.

The GGOV1 model was developed as a general purpose turbine-governor model to be used for dynamic simulation studies. GGOV1 is appropriate for studies where the plant remains connected to a large grid; that is for all conventional grid interconnection studies. The model can also be used for load rejection studies to simulate the system response to loss of loads. For large load pick up studies (e.g. black start) the model may not provide accurate results since guide vane dynamics, are not included in the GGOV1 model.
