Technical Abstract: A 1500 W wind turbine has been continuously tested since 1992 at the USDA-ARS Conservation and Production Research Laboratory, Bushland, TX, for pumping water for livestock and domestic uses. This wind turbine used a permanent magnet alternator that provided variable-voltage, variable- frequency, 3-phase AC electricity which powered off-the-shelf submersible motors and centrifugal pumps without the use of any power conditioning equipment. Data collected during this period included: flow rate, wind speed, pressure (simulated pumping depth), voltage, current, frequency, and electrical power. Data were collected for four different submersible pumps operated at pumping heads ranging from 20 m to 100 m. The optimum pump was found to be a function of the pumping head and the wind speed resource. A chronological history of significant events and failures of the pumping system is also documented. This wind turbine was available 93% of the time eover the past six years. Individual contributions to downtime were: problems with the wind turbine/controller (5%), icing of the blades (1%), problems with the motor/pump (1/2%), and miscellaneous (1/2%). After correcting initial start-up problems, the 1500 W wind turbine proved very reliable.
