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.

New  technical  developments,  such  as  in  the  field  of  frequency  drives  of  technological  units,  electrified transport, wind, and solar power plants, apply devices built on the basis of powerful transistors. Modern devices designed on these elements  are  powerful  generators  of  higher  harmonics  of  currents  that  penetrate  the  grids  of  power  systems.  It  requires  the development of measures and means to limit the higher harmonics of currents in the electrical grids.
