Abstract In the long term dynamic simulation of power systems, the accurate modeling of the turbine-governors is an essential. This paper investigates the modeling and parameter identification of turbine-governors by field tests. The typical response characteristics of steam turbines and gas turbines under speed step change tests are analyzed. Based on the result of the analysis, a new turbine-governor model structure, known as the response model, is proposed and its applicable range is also discussed. Then, based on the field test data, the parameters of the response model for a typical steam unit are identified by the simplex method. Later, these parameters are verified by a large frequency disturbance test. Comparison between the simulative curves and the test curves shows that the response model and its identified parameters can simulate the behavior of the turbine-governor under large frequency disturbance correctly.

Key words： Turbine-governor response model primary frequency control speed step change test large frequency disturbance test simplex method parameter database
