Wind Resource Analysis On-site measurements are analysed using our purpose built software tools allowing for an unrivalled and unbiased analysis and estimate of the wind speeds and directions the site would be expected to experience over the turbine design life time. The long term wind regime is assessed using our validated wind library covering the onshore regions of the world in an unprecedented high resolution. Complexity Factors such as terrain complexity and wind from certain directions can influence the efficiency of your wind power plant. SiteDesign® takes account of this and other issues, including wind power plant geographic layout. Turbulence Turbulence can sometimes force lower-speed operation, or even shut down wind turbine generators. An analysis and estimate of the expected wind turbulence levels can help ensure your site is designed to minimise this risk. SiteDesign® takes this into account when optimising the layout for your wind power plant. Service Cost Assessment An assessment of the operational lifetime cost to service the wind power plant is conducted and is one of the parameters of the SiteDesign® analysis. This long term assessment is derived from using recordings in our massive performance databases which are linked to turbine specific climatic and operational conditions. Optimised Financial Performance SiteDesign® generates an operational index map of the wind power plant site, taking into account the estimation of both the projected annual revenue and the operational expenses associated with each grid point on the index map. Using this operational index map, the optimum site layout for Vestas’ wind turbines can be designed.
