Design and implementation of fuzzy logic controller for static switching control of voltage generated in self-excited induction generator

Wind energy, which is one of the major sources of renewable energy sources, may be extracted using self-excited induction generators and are preferred in hilly, rural and remote areas where grid connections are either costly or not feasible. However, one of the major problems associated with such generators is its poor voltage regulation. This paper presents the application of fuzzy logic controller to regulate the terminal voltage of such machines by static switching control of dump load. It has been shown that such proposal as presented will enhance the overall dynamic performance of the machine. The simulation results with proposed control model under varying consumer load are found to be much better than with PI controller and electronic load controller.
