چکیده :

Due to the depletion of fossil resources, employing renewable energies has been increased and experienced significant growth in recent years. Among these long-lasting sources, wind energy is one of the best sources for energy supply in the entire world due to its availability and continuity. The specific generators used in wind turbines, such as doubly-fed generators, have dominated wind turbines due to their low cost. But the main issue associated with these types of generators is their sensitivity to voltage drop. In fact, with the occurrence of faults within the grid and the resulting voltage drop, the current on the stator side increases and due to the connection between the stator and the rotor, this current is transferred to the rotor leading to utilizing complex and expensive electronic power converters. In this paper, the design and electromagnetic analysis of brushless salient pole induction generator with direct current auxiliary field winding is investigated. On the proposed stator structure, in addition to the phase windings, there are also field windings while there are no windings placed on the rotor. The proposed structure can easily manage the flux through the simple control of the direct current of the field winding. This way, generator output voltage is effectively controlled. The analysis and simulation results guarantee the suggested structure.
