The aim of this work is to combine electromagnetic compatibility standardization and control strategy of low-voltage distributed generations in order to define possible impact of the generation unit on power quality at the point of common coupling with low-voltage distribution network. Selected relations between power quality indices and parameters as well as regulation characteristic of the distributed generation is discussed. Verification of predicted impact of the distributed generation on power quality is performed using a field-measurement case study of power quality behaviour in real photovoltaic system connected to low-voltage distribution network.

Celem pracy jest wykorzystanie normalizacji stosowanych w zagadnieniach kompatybilności elektromagnetyczne oraz zasad regulacji źródeł rozproszonych niskiego napięcia w celu określenia możliwego wpływu źródła rozproszonego na zaburzenia jakości energii elektrycznej w punkcie przyłączenia. W pracy przedstawiono wybrane relacje pomiędzy parametrami źródła oraz stosowaną charakterystyką regulacyjną źródła a możliwym wpływem na parametry jakościowe w punkcie przyłączenia. Weryfikacja przewidywanego wpływu rozważanego źródła na parametry jakościowe zrealizowana jest na podstawie rzeczywistych pomiarów zaburzeń jakości energii w punkcie przyłączenia systemu fotowoltaicznego.
