An Overview of Synchronization Methods of Grid Fundamental Signal

Abstract:

The synchronization signals of the grid fundamental wave are applied to various fields, such as power protection system, power quality system, and large power grid interconnection. As new problems emerging during the development of the grid, the synchronization methods keep continuous improved. These methods appeared in accordance with the time sequence are zero crossing detection method, the maximum value algorithm, the Fourier transform method, filter method, and phase locked loop method. In this paper, the typical methods are studied and made analysis of their characteristics, which can be used as reference in the practical applications.
