摘要

A robust synchronization method based on least mean square is proposed for the real time detection of fundamental symmetrical components, including positive, negative and zero sequence. The new architecture is composed of three parallel structures providing estimation of each phase fundamental 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 results in order to verify correctness and validity of the algorithm.
