Wind resource estimation and mapping at Ail al-Gharby site (East-South of Iraq)‎ using WAsP model

Abstract EN

The wind atlas analysis and application program, WAsP, is used to assess wind energy potential، wind climate from geostrophic winds of a given area.

In this paper, metrological data from Ali Algharby station was used to predict the wind resource and wind turbine energy production at Ali Algharby site.

Data from metrological station was used to draw up observed wind climates at the anemometer site.

Site contour map was digitized using WAsP Map Editortool.

Observed wind climate, digitized contour map, terrain roughness length, obstacle groups and their porosity were used as input to the WAsP model.

Vestas V182, 1.65 MW turbine was used.

Weibull probability distribution graph of wind speed, power density were drawn.

A directional wind rose for January to December 2011 were drawn for site.

Results showed that the studied area have Annual Energy Production (AEP) about 5 GWh as mean value.

The calculation was obtained at 70 m hub height for the turbine and the roughness length (0.0, 0.03, 0,1,0,4, 1.5) m for the selected area.
