Wind energy for irrigation: wind-assisted pumping from wells. Final report

Technical Report ·
OSTI ID:5281186
; ; ; ;
Work is reported on a project whose objectives were: to assemble a complete wind-powered pumping system for irrigation wells in the Southern Great Plains; to adapt or modify existing pumping equipment so that it could effectively be powered by a vertical-axis wind turbine; to develop a data collection system for collecting, recording and processing on-site wind data and mechanical, electrical and hydraulic systems data; to combine data from all systems in an overall analysis that will permit an engineering evaluation of the complete system; to develop a dynamic mathematical model of the pumping system which includes the most appropriate model of the vertical-axis wind turbine; and to make an economic analysis of the wind-powered pumping system and construct a model for predicting the economics of such systems in general. The pumping system uses both a vertical-axis, or Darrieus, wind turbine designed to produce 40 kW in a 15 m/s wind and an electric motor to power a conventional vertical-turbine irrigation pump. The wind turbine furnishes power to the pump only when the windspeed exceeds 6 m/s and is used to reduce the load on the electric motor rather than to replace the motor. The wind-assisted pumping system and its operation are described, as is the data collection system, and the results of the performance data analysis for the wind turbine and the pumping system are discussed. The system's annual energy output is predicted, and the economics are analyzed. (LEW)
