“…This has been attributed to the inaccurate modeling of many of the thermal unit governors (including Gas Turbines) in the WECC. Since early 2001, WECC has proposed new criteria for Frequency Responsive Reserves (FRR) making the need to develop a more accurate governor model for dynamic simulations imperative [25]- [30]. A model shown in Fig.…”

“…This limit is imposed in the gas turbine model with a curve that relates exhaust temperature to several other engine variables [25]- [30]. The load management element will regulate the turbine power to the setpoint , simulating effectively the adjustments necessary due to the AGC commands.…”

“…Turbine dynamics is essentially considered to be in direct proportion with fuel flow (the relevant time constants are longer compared to the turbine time constants) and hence can be simply represented by a single lead-lag block. Many of the GAST models previously used in the system were replaced by the developed GGOV1 model which is explained in further detail in [25]- [30].…”

Gas turbines have become increasingly popular in the different power systems, due to their lower greenhouse emission as well as the higher efficiency, especially when connected in a combined cycle setup. With increasing installations of gas turbines scheduled in different countries, the dynamics of the gas turbines become increasingly more important. In order to study such dynamics, accurate models of gas turbines are needed. This paper presents a comparative analysis and an overview of various models of gas turbines published in different literature.

“…A modern servo-mechanism is usually controlled by DEH and consists of a servo-controller, a servo-valve, a servomotor, a displacement transducer, and a check-valve [5,6]. The input signal of the servo-mechanism control loop is the required opening value of the servo-valve, while the output signal is the servo-motor position which is also the real opening valve of the servo-valve.…”

The theoretical modeling, parameters test and model correction for a steam turbine (ST) governor are discussed. A set of ST Governor system model for power system simulation is created based on this research. A power system simulation for an actual power grid accident is conducted using this new model and the comparison between the simulation and actual data show that the results are satisfactory.

“…An important result of such effort was the publication of recommended or standard simulation models for generators, excitation systems, turbine/speed governors and power system stabilizers that simplify the modeling effort while still representing the performance of these equipment with enough accuracy and detail for the analysis at hand [1][2][3][4][5][6][7][8].…”

This paper focuses on a few different aspects of the dynamic model validation process. It briefly describes the undergoing development of NERC standards that would require the validation and periodic re-validation of dynamic simulation models and then discusses the capabilities and shortfalls of the different approaches that might be applied to comply with such requirements. Finally, the paper presents some brief examples describing the use of such models in system simulations and how these results could affect the technical and economical operation of power plants.
