Most of FACTS devices and grid connected converters need the information about the frequency and phase of the grid for synchronization and control. In some cases, the value to be measured that is used as synchronization signal is at remote bus or at a different voltage potential, which would require expensive high voltage measurements or high bandwidth communication. A new synchronization method for...
Doubly-fed induction generator (DFIG) is the most common type of generators for wind power generation, because of their high energy yield and the possibility of generating power at variable speeds. For most papers in literature, only the synchronization and power generation of DFIGs, but not the transition between them, are discussed. This paper presents a method to control the transition of DFIGs...
