The advantage of DFIGs is to maintain a reliable operation of the network with improved power quality. Differences between Synchronous and Induction Generators: WebThe main difference between synchronous generator and induction generator is the link between rotor speed and ac supply frequency generated by the machine. For a synchronous machine, the frequency is synchronous to the speed. If a load appears, the speed decreases so the frequency of the ac system generated by the machine. team ftk
