Site-specific assessment of wind turbines: A pragmatic approach. In Germany formal building regulations often request site-specific assessments of all Wind Turbine Generators (WTG) including new and existing ones. When using the current technical methods and guidelines, the assessment cannot be completed for all WTG, if the wind farm consists of different WTG types (produced by different manufacturers). Thus, in order to comply with the regulations, operators of WTG are forced to curtail the power of many WTG. In the present document a technical method is described extending the existing methodo logy for site-specific assessments according to DIBt 2012. The technical method describes a simplified load estimation model, which would enable other expert engineers – not only the manufacturer of the WTG – to carry out capacity checks as well.
