combination of analyses of SCADA data and a nearby wind measurement
comparison to reanalyses data, met station data and aj production indices
Results:
inconsistencies related to the power curve could be detected in the past, including longer periods with reduced availabilities and a variety of curtailments
more recently, the operational behaviour of the turbines has improved; however, some inconsistencies still occur around rated wind speed which need to be analysed further with respect to an additional load on the turbines
realistic performance of the wind turbines in the wake of neighbouring turbines, i.e. no under-performance with respect to the power curve

Oldershausen, 15 May 2018: A new study of aj shows that the wind resource of the years around 1990 cannot be considered as very exceptional any more. Consequently, these years must be included in the long term reference period, if the result should be balanced. Download of the report Wind D NAO-Index E 15.05.2018 aj
