Determining the proper motor size for two wind turbines used in water pumping
- Dept. of Agriculture, Bushland, TX (United States). Agricultural Research Service
Two different size wind turbines were tested for pumping water at the USDA-Agricultural Research Service, Bushland, Texas. One was a three-bladed 7.0-m diameter wind turbine which was rated at 10 kW at a 12.1 m/s wind speed. The other was a two-bladed 2.75-m diameter wind turbine which was rated at one kW at a 11.0 m/s wind speed. Both wind turbines used a permanent magnet alternator to provide electrical power to a motor which powered a submersible pump. The one kW wind turbine can be used for watering livestock or providing water for a family of four. The 10-kW wind turbine can be used for small scale irrigation or providing water for a small village. During the testing of both wind turbine/motor/pump systems, two different motors were tested. The 5.6 kW motor had a 10 percent advantage in system efficiency over the 3.8 kW motor for the 10-kW wind turbine. For the one kw wind turbine the maximum system efficiency was the same for both the 0.38 kW and 0.56 kW motors, but occurred at different wind speeds.
