5 Days Small Wind Turbine Construction Workshop

Starts from 31st October, 2017 (Tuesday) to 4th November, 2017 (Saturday)

Venue: Kathmandu University, Technical Training Center

Timings: 9:00AM to 5PM

Construction Course for building a 2.4m small wind turbine






Brief summary

During this 5 day course a 600W small wind turbine with 2.4m rotor diameter will be constructed from scratch, using simple raw materials like wood for the blades, steel for the mounting frame and tail, copper wire for the coils and neodymium magnets cast in resin for the generator. The wind turbine will be built with subdivided focus groups working in parallel sessions of woodworking, metalworking and generator fabrication, along with short breaks to share/question what we have learned with the whole team.

Woodworking will involve hand carving the blades of the rotor using drawknives and spokeshaves, planes and chisels. Metalworking will involve fabricating the steel frame to support the generator, blades and tail, with the use of welding, grinding and drilling techniques. Generator fabrication will involve winding coils, placing magnets, preparing plywood moulds and casting the stator coils and rotor magnet disks into resin. Basic woodworking and metal working skills will be taught during the course, and will enable all participants with enough hands-on experience to complete the wind turbine construction.

Although most of the course is practical, an introduction to the basic theory of small wind turbine systems will cover important aspects such as the wind energy resource, aerodynamics and blades, electromagnetism and generators, the furling tail system, tower installation and connection to a battery bank. Apart from these short presentation briefs during the workshop, chances for discussions on the topics will come up throughout the duration of the course.

Apart from constructions and basic theory, the maintenance procedure of the small wind turbine will also be described.

Through the construction of a 2.4m rotor diameter small wind turbine, participants will get the chance to develop practical skills such as woodworking, metalworking and working with resins, along with skills on installing small wind turbines. Basic theoretical knowledge on wind energy systems will be developed, such as aerodynamics and electromagnetism.

Transportation information:

  • For people coming from Kathmandu, a bus will be available from Koteshwore bus park which will leave at 7:45am sharp in the morning. It takes approximately 1 hour to reach Kathmandu University. For all participants preferring to travel by bus, please reach the buspark before this time considering few minutes extra time to find/reach the bus at the bus stop. Each day after the workshop, the bus will take participants back to Koteshwore from Kathmandu University.
  • Bus No: Ba 4 Kha 613

Food:

  • There is a provision of lunch each day during the course in the university canteen.

Small Wind Turbines

Kathmandu Alternative Power and Energy Group has been working on constructing small wind turbines since 2004 by conducting various projects utilizing locally available resources.

The wind turbines that will be built in the workshop are based on the designs of Hugh Piggott. The wind turbines can be constructed with the use of common materials, simple manufacturing techniques and basic tools, providing a low cost small wind turbine for practitioners. Hundreds of homemade small wind turbines have been constructed worldwide using these designs, and have proven to be robust, efficient, easy to maintain and quick to repair. Typical applications of locally manufactured small wind turbines are development projects such as electrification of village communities, educational projects in universities and schools and sustainability projects such as renewable energy electrification of eco-villages.
