Project Description
Wind power is one of the renewable energy sources which has gained considerable attention, owing to its environmentally friendly, economical, and reliable operation. In this regard, improving the performance of its components results in a more efficient and reliable wind power generation system. Distributed wind power generation systems often require a novel approach in generator design, especially for low power machines. Gearless wind generator designs are particularly preferred for these applications. In this regard, improving the performance of the mechanical part can highly affect the whole system performance in such a way that, increasing the coefficient of wind turbine results in a higher generated power. The process of converting the kinetic energy of wind into mechanical energy of rotational motion of rotating masses using a single-rotor wind turbine in accordance with the Betz’s law is limited to 59% of available wind energy. Thus, this project is to design and fabricate a novel dual rotor counter rotating field excited flux switching generator (CR-FEFSG) for advance counter rotating wind turbine application to improve wind energy conversion efficiency. Due to dual counter rotating wind blades configuration, counter rotating wind turbine results higher power than the conventional single blade wind turbine systems. Moreover, counter rotation can be achieved in the same resource with dual rotor configuration therefore, such low cost and higher power density generators are preferable to wind turbine application. It is worth mentioning that in comparison with conventional design where both stator and rotor rotates, the proposed dual rotor configuration rotates only by eliminating the requirements of the slip rings and extra mechanical accessories. Additionally, due to direct drive configuration, the requirements of gear box are eliminated. Thus, ease in manufacturing process and eliminates constant maintenance cost in compared to existing slip ring and geared generators.
