Synchronization of VSCs to the Grid
摘要
This chapter presents the synchronization of voltage source converters (VSCs) to the grid. In Sec. 4.1, the connection of a VSC to the grid based on the grid equivalent circuit and the energy transfer is explained. Sec. 4.2. gives an overview of different synchronization principles. Basic and advanced voltage-based synchronization concepts are shown and evaluated in Sec. 4.3.
