Experimental studies of the main indicators of power quality at the terminals of autonomous low-power generators were carried out. The content of higher voltage harmonics, as well as voltage and frequency deviations from the nominal value were determined. In the course of the research, the technical means of data collection and analysis by National Instruments were used. The main indicators of the power quality of autonomous inverter generators are shown to fully comply with the EN 50160-2022 standard.

Brushless excitation systems of synchronous generators provide non-contact transfer of the excitation power to the generator rotor in case absence of a commutation in rotor circuit. Such systems have a long response time of terminal-voltage regulation caused by the additional rotating machine (exciter). Using of fast-acting compound circuit allows improving dynamic parameters of terminal-voltage regulation in modes of sharp voltage variation and short circuit in line.
