A robust synchronization method based on least mean square is proposed for the real time detection of fundamental and harmonic symmetrical components, including positive, negative and zero sequence. The new architecture is composed of three parallel structures providing estimation of each phase fundamental and harmonic components delivered into a linear matrix transformation for grid sequence extraction. To achieve frequency adaptation, a combination of least mean square and phase locked loop is used. The paper presents excellent simulation and experimental results in order to verify correctness and validity of the algorithm.

W artykule opisano opracowaną metodę synchronizacji z siecią, wykrywającą w czasie rzeczywistym częstotliwość podstawową oraz wyższe harmoniczne, w tym składową zgodną, przeciwną i zerową. Architektura składa się z trzech równoległych estymatorów harmonicznych dla każdej fazy. Po przetworzeniu danych i wyznaczeniu składowych, dokonywana jest synchronizacja, z wykorzystaniem metody najmniejszych kwadratów oraz PLL. Przedstawione zostały wyniki symulacyjne i eksperymentalne.
