DESIGN AND IMPLEMENTATION OF AN EDUCATIONAL AXIAL FLUX WIND TURBINE/GENERATOR

Abstract

Wind turbines capture low and high speed winds throughout the world. This paper presents design and implementation of an educational, small-scale, axial flux wind turbine-generator. An axial wind turbine is easy to build, fun to learn and cost effective system designed using in almost any windy location in the world. Two students at the University of Northern Iowa (UNI) enrolled in a Bachelors of Science in the Electrical and Information Engineering Technology (EIET) major, have spent many hours researching various wind turbines. The subject matter presented in this paper are (1) design and build a cost effective 0.5 kW wind turbine capable of producing 12-48 V direct current (DC), (2) build two wind turbines with different configurations, (3) build a traveling display that can be taken to remote locations and educate anyone with questions, and (4) experiment with variable loads and blade designs. Senior students involved in this project have shown excellent progress by developing their technical and teamwork/social skills as part of the Senior Design I and II core courses and have been successfully completing their course requirements.

I. Introduction and Problem Definition

Worldwide, the need for electrical power has increased exponentially. Energy needs versus climate change relation has been a subject of a significant debate in the world. Recent scientific evidence indicates that global warming is underway 1. Observed changes show that despite large variations from year to year, the global mean temperature has risen significantly in the last century 1. Expected future increases in global average temperatures may have adverse, possibly irreversible effects on the climate, including changes in regional temperature patterns, more frequent extreme weather events and a rise in sea levels worldwide. Climate change may affect human life and the ecology of the planet in a variety of ways, including changes in agriculture, water supply and quality, human settlements, and human health, in addition to affecting biodiversity and migratory patterns and causing other eco-system disturbances 1.

In recent years, climate change science has made it clearer than ever before that human-induced global warming is underway. Climate change scenarios prepared by the Intergovernmental Panel on Climate Change (IPCC) show a wide range of possible impacts from global warming in the next century 2. The observed global warming is largely due to increases in the emissions of greenhouse gases (GHGs) such as CO2, CH4, NO2, HFCs, PFCs and SF6 from various human and industrial activities. Ice core data show that changes in the atmosphere since pre-industrial times far exceed changes from the preceding 10,000 years 1-2. Since ice cores trap air bubbles from the atmosphere over time, this provides scientists to measure directly levels of greenhouse gases associated with different times in history 1-2. These changes are driven by worldwide population and economic growth, and underlying production and consumption of fossil energy, agricultural activity and land use change.
