The mathematical model of an electromechanical system with an asynchronous generator with rotor’s current regulation by frequency converter with an autonomous voltage inverter controlled by current controllers has been described in the article.
The transient electromagnetic processes in the power generation system with turbo- generator and brushless excitation system in a mode of initial excitation of turbo-generator are analyzed in the article. The research was carried out in the hybrid system that combines a computer model of a power part with the real excitation controller. The influence of setting the automatic control system on quality of voltage regulation and generator excitation current regulation is analyzed.
