Wind turbine for family farming in semi-arid areas with technological innovations for low wind speeds

Abstract

Family farming is an important segment of Brazilian agribusiness, and has a large part in producing that food which is essential for food security in Brazil, so the supply of energy to these farmers becomes necessary. One alternative is wind energy; however a challenge in using the wind on small properties in the State of Ceará are its lowspeed conditions of operation (winds < 6 m s-1). The objective of this work was to propose a wind-energy system for small farms in the State of Ceará, having technological innovations. All the systems were designed and scaled employing an innovative turbine, and are suitable for small properties. The cost estimate indicates a low value for acquisition, and by using smart grids and the distribution of generated energy, income can be produced.
