Deriving model parameters from field test measurements

ISSN 0895-0156/02/$17.00©2002 IEEE Amajor component of any power system simulation model is the generating plant, which comprises three major subcomponents of interest: the generator, excitation system, and the turbine/governor. Accuracy of representation is dependent both on the structure of the component models and the parameter values used within those models. Since the accuracy of power system stability analysis depends on the accuracy of the models used to represent the generators, excitation control systems, and speed governing systems, the parameters used in those models could affect the calculated margin of system stability. Use of more accurate models could result in increases in overall power transfer capability and associated economic benefits. Alternately, inaccurate simulation models could result in the system being allowed to operate beyond safe margins. To assist in these efforts, Power Technologies, Inc.
