Development of Mini Generator based on Wind Turbine Principle

Shortage of resources to generate electricity is one of the big issue nowadays. Recently, in Malaysia, electricity is generated from fossil fuels and water flow pressure. However, fossil fuels are facing extinction problem due to the limited production of these sources while flow pressure water also has limitation to supply electricity energy to the residents. Besides, the usage of fossil as energy resources affect the environment. Thus, this research proposed a mini wind turbine as an alternative source to generate electricity for consumer daily usage. The designed generator is developed with different number of blades and the operation is implemented by using arduino. The analysis of the effectiveness of the designed system is measured through different evaluation of produced voltage based on different number of fan blades and wind speed. The result shows that for ideal and simple wind turbine structure, the increment of rotational speed produced higher voltage and current. Thus, the system can be used an alternative source of electricity generator for small-scale individual user.
