Power performance measurements verification of electricity producing wind turbines


IEC 61400-12-2 specifies a procedure for verifying the power performance characteristics of a single electricity-producing, horizontal axis wind turbine. This standard is intended to be used when the specific operational or contractual specifications may not comply with the requirements set forth in IEC 61400-12-1:2005. The procedure can be used for power performance evaluation of specific turbines at specific locations, but equally the methodology can be used to make generic comparisons between different turbine models or different turbine settings.

This IEC 61400-12-2 standard describes how to characterize a wind turbine’s power performance in terms of a measured power curve and the estimated AEP. The procedure also provides guidance on determination of measurement uncertainty including assessment of uncertainty sources and recommendations for combining them into uncertainties in reported power and AEP.
