Abstract: This work proposes a practically feasible and distinct method of harvesting wind energy for urban and rural rooftops. This technique is especially useful for distributed generation. A one-fourth scaled version of a new type of wind energy conversion system (WECS) has been presented. The novelty of the reported WECS lies in the usage of a magnetically levitated vertical axis wind turbine (VAWT) along with dynamic guide vanes system. The usage of magnetic levitation results in loss minimisation and efficiency maximisation. To tap maximum wind energy, the guide vanes are programmed to dynamically change their angle according to the wind speed. This paper also presents the utility of an axial flux permanent magnet (AFPM) generator for VAWT systems. An experimental model has been developed and its results have been presented. The experimental results have been put to use for developing a model of the VAWT system using fuzzy inference system (FIS).

Keywords: distributed generation; guide vanes; magnetic levitation; vertical axis wind turbine; VAWT; Venturi effect.
