| Zusammenfassung |
| Crop irrigation is a major consumer of energy that can be resolved with renewable ones, such
as wind, which has experienced recent developments in the area of power generation.
Therefore, wind power can play an interesting role in irrigation projects in different areas [1].
A simple methodology has been developed in previous papers for technical evaluation of
windmills for irrigation water pumping [2]. This methodology can determine the
feasibility of the technology and the levels of daily irrigation demand satisfied by
windmills.
The present work compared the possibilities of this methodology adjusting the
three-hourly wind velocity to the Weibull II distribution function, without considering the
time sequence [2], or processing wind data using time series analysis. The study was applied
to practical cases of wind pumps for irrigation of crops, both in the outside (corn) and inside
greenhouses (tomato).
The analysis showed that the use of three hourly time series analysis supplied a more
realistic modelling of the situation with a better optimization of the water storage tank of the
wind pump facility taking into account the risk of calm periods in which the pumping is
null. A factor to consider in this study is available precision of the wind sampling
rate.
