Wind turbines - Part 12-2: Power performance of electricity-producing wind turbines based on nacelle anemometry
IEC 61400-12-2:2013 specifies a procedure for verifying the power performance characteristics of a single electricity-producing, horizontal axis wind turbine, which is not considered to be a small wind turbine per IEC 61400-2. 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.

Eoliennes - Partie 12-2: Performance de puissance des éoliennes de production d'électricité basée sur l'anémométrie de nacelle
La CEI 61400-12-2:2013 spécifie un mode opératoire pour vérifier les caractéristiques de performance de puissance d'une éolienne simple de production d'électricité à axe horizontal, qui n'est pas considérée comme une petite éolienne selon la CEI 61400-2. Cette norme est destinée à être utilisée lorsque les spécifications d'exploitation ou contractuelles spécifiques peuvent ne pas être conformes aux exigences présentées dans la CEI 61400-12-1:2005. Ce mode opératoire peut être utilisé pour l'évaluation de la performance de puissance de turbines spécifiques à des emplacements spécifiques, mais cette méthodologie peut également être utilisée pour effectuer des comparaisons génériques entre différents modèles de turbines ou différents réglages de turbines.
Vetrne turbine - 12-2. del: Ugotavljanje elektroenergetskih zmogljivosti vetrnih elektrarn po načelu merjenja hitrosti vetra skozi gondolo
Ta del standarda IEC 61400-12 določa postopek za preverjanje značilnosti elektroenergetskih zmogljivosti posamezne vetrne turbine s horizontalno osjo, ki proizvaja električno energijo in v skladu s standardom IEC 61400-2 ni mala vetrna turbina. Ta standard naj bi se predvidoma uporabljal, ko določene operativne ali pogodbene specifikacije niso v skladu z zahtevami standarda IEC 61400-12-1:2005. Postopek se lahko uporabi za vrednotenje elektroenergetskih zmogljivosti določenih turbin na določenih lokacijah, vendar se lahko metodologija prav tako uporabi za splošne primerjave med različnimi modeli ali nastavitvami turbin.
Na elektroenergetsko zmogljivost vetrne turbine, za katero sta značilna izmerjena krivulja električne energije in ocenjena vrednost AEP na podlagi hitrosti vetra, izmerjeni skozi gondolo, vpliva rotor turbine (tj. povečana ali zmanjšana hitrost vetra). Hitrost vetra, izmerjena skozi gondolo, se popravi za ta vpliv popačenja toka. Postopki za določanje tega popravka bodo vključeni v metodologijo. V standardu IEC 61400-12-1:2005 je anemometer na meteorološkem stolpu, ki je od dva do štiri premere rotorja proti vetru od preskusne turbine. Ta položaj omogoča neposredno merjenje »prostega« vetra z minimalnimi motnjami rotorja preskusne turbine. V postopku standarda IEC 61400-12-2 je anemometer na gondoli preskusne turbine ali v njeni bližini. Na tem položaju anemometer meri hitrost vetra, na katero močno vplivata rotor preskusne turbine in gondola. Ta postopek vključuje metode za določanje in uveljavitev ustreznih popravkov zaradi teh motenj. Kljub temu je treba opozoriti, da ti popravki povečajo netočnost merjenja v primerjavi z ustrezno konfiguriranim preskusom, izvedenim v skladu s standardom IEC 61400-12-1:2005. Ta standard IEC 61400-12-2 opisuje, kako opisati elektroenergetske zmogljivosti vetrne turbine, kar zadeva izmerjeno krivuljo električne energije in ocenjeno vrednost AEP. Izmerjena krivulja električne energije se določi z zbiranjem istočasnih meritev hitrosti vetra, izmerjene skozi gondolo, in izhodne moči v obdobju, ki je dovolj dolgo, da se ustvari statistično pomembna zbirka podatkov pri različnih hitrostih vetra in pri različnih vetrnih in atmosferskih pogojih. Da bi se krivulja električne energije točno izmerila, se hitrost vetra, izmerjena skozi gondolo, prilagodi s funkcijo prenosa, da se oceni hitrost vetra v prostem pretoku. Postopek za merjenje in potrditev takšne funkcije prenosa je opisan v tem dokumentu. AEP se izračuna z uporabo izmerjene krivulje električne energije pri referenčnih porazdelitvah frekvence hitrosti vetra, pri čemer se predvideva 100-odstotna razpoložljivost. Postopek prav tako podaja smernice za določanje netočnosti merjenja, vključno z oceno virov netočnosti in priporočili za njihovo združevanje pri evidentirani električni energiji in vrednostih AEP.
