Parameter identification of different models of automatic voltage regulation system

In this paper, the parameters of the two different automatic voltage regulation (AVR) system models are estimated using operational data of synchronous generator (SG). The operational data are obtained from the simulation model of the complete AVR system, which is developed using the technical documentation of the excitation system of 40 MVA SG from the hydropower plant (HPP) Perucica in Montenegro. The parameters of the considered AVR system models are extracted using a metaheuristic equilibrium optimizer (EO) algorithm. The mutual comparison between the two considered models, in terms of accuracy and precision, is provided.
