1. A method for modeling an excitation system for a synchronous electrical power generator comprising: selecting a standard exciter model to model the excitation system, wherein the standard exciter model is selected from a plurality of standard excitation system models stored electronically; wherein the selected standard exciter model is selected based on a similarity to the excitation system; collecting data from the excitation system by collecting frequency response data from the generator resulting from a perturbing signal applied to the excitation system; determining model parameter settings for the selected standard exciter model using the frequency response data; verifying the selected standard exciter model with the determined model parameter settings by comparing an output of the selected standard exciter model with the determined model parameter settings to a corresponding output of the excitation system; storing electronically the verified selected standard exciter model with the determined model parameter settings, and generating a report of the verified selected standard exciter model with the determined model parameter settings.
