【 摘 要 】

The optimization idea and method for model construction and model parameters simulation was introduced which based on the general requirements of power grid stability analysis. In the process of parameter identification, a identification method based on genetic algorithm was adopted and implemented using Matlab and its simulation toolbox. Meanwhile, It introduce "turbine speed governing system collaboration curve" in order to adapt the diversity and strong nonlinear characteristics of thermal power units. From the situation of the modeling test in some thermal power generating unit, the Model parameters can satisfy the requirement of power grid stability analysis.
