Wind energy generation systems - Part 12-2: Power performance of electricity producing wind turbines based on nacelle anemometry

IEC 61400-12-2:2022 specifies a procedure for verifying the power performance characteristics of a single electricity-producing, horizontal axis wind turbine that is not considered to be a small wind turbine per IEC 61400-2. It is expected that this document be used when the specific operational or contractual specifications do not comply with the requirements set out in IEC 61400-12-1. The purpose of this document is to provide a uniform methodology of measurement, analysis, and reporting of power performance characteristics for individual electricity producing wind turbines utilising nacelle-anemometry methods. This document is intended to be applied only to horizontal axis wind turbines of sufficient size that the nacelle-mounted anemometer does not significantly affect the flow through the turbine’s rotor and around the nacelle and hence does not affect the wind turbine’s performance. This second edition of IEC 61400-12-2 is part of a structural revision that cancels and replaces the performance standards IEC 61400-12-1:2017 and IEC 61400-12-2:2013. The structural revision contains no technical changes with respect to IEC 61400-12-1:2017 and IEC 61400‑12‑2:2013, but the parts that relate to wind measurements, measurement of site calibration and assessment of obstacle and terrain have been extracted into separate standards.

Systèmes de génération d'énergie éolienne - Partie 12-2: Performance de puissance des éoliennes de production d'électricité fondée sur l'anémométrie de nacelle

L'IEC 61400-12-2:2022 spécifie une procédure de vérification des caractéristiques de performance de puissance d'une éolienne simple de production d'électricité à axe horizontal, qui n'est pas considérée comme un petit aérogénérateur selon l’IEC 61400-2. Il est prévu que le présent document soit utilisé lorsque les spécifications de fonctionnement ou contractuelles spécifiques ne sont pas conformes aux exigences définies dans l’IEC 61400‑12‑1. Le présent document a pour objet de fournir une méthodologie uniforme de mesure, d'analyse et de rapport des caractéristiques de performance de puissance de chacune des éoliennes de production d'électricité qui applique les méthodes d'anémométrie de nacelle. Le présent document est destiné à être appliqué uniquement aux éoliennes à axe horizontal et de taille suffisante pour que l’anémomètre monté sur la nacelle n’ait pas d’influence significative sur l’écoulement d’air dans le rotor de l’éolienne et autour de la nacelle, et n’ait donc pas d’influence sur les performances de l’éolienne. Cette deuxième édition de l’IEC 61400-12-2 fait partie d’une révision structurelle qui annule et remplace les normes de performance IEC 61400-12-1:2017 et IEC 61400-12-2:2013. Cette révision structurelle ne contient aucune modification technique par rapport à l'IEC 61400‑12‑1:2017 et l'IEC 61400-12‑2:2013. Toutefois, les parties relatives aux mesurages du vent, au mesurage de l'étalonnage du site et à l'évaluation des obstacles et du terrain ont été extraites vers des normes distinctes.

Sistemi za proizvodnjo energije na veter - 12-2. del: Ugotavljanje elektroenergetske zmogljivosti vetrnih turbin po načelu merjenja hitrosti vetra skozi gondolo (IEC 61400-12-2:2022)

Ta del standarda IEC 61400-12 določa postopek za preverjanje elektroenergetske zmogljivosti posamezne vetrne turbine s horizontalno osjo, ki proizvaja električno energijo in v skladu s standardom IEC 61400-2 ni mala vetrna turbina. Ta dokument naj bi se predvidoma uporabljal, ko določene operativne ali pogodbene specifikacije niso v skladu z zahtevami iz standarda IEC 61400-12-1. Postopek se lahko uporabi za vrednotenje elektroenergetske zmogljivosti določenih turbin na določenih lokacijah, vendar je metodologijo mogoče uporabiti tudi za splošne primerjave med različnimi modeli ali nastavitvami turbin. Namen tega dokumenta je zagotoviti enotno metodologijo merjenja, analize in poročanja o elektroenergetski zmogljivosti posameznih vetrnih turbin, ki proizvajajo elektriko po načelu merjenja hitrosti vetra skozi gondolo. Dokument naj bi se uporabljal le za vetrne turbine z vodoravno osjo, ki so dovolj velike, da anemometer, nameščen na gondolo, ne vpliva bistveno na pretok skozi rotor turbine in okoli gondole ter zato ne vpliva na delovanje vetrne turbine. Namen tega dokumenta je, da se metode, predstavljene v njem, uporabijo, kadar zahteve iz standarda IEC 61400-12-1 niso izvedljive. To zagotavlja, da so rezultati v okviru trenutnega stanja tehnike za instrumentacijo in merilne tehnike čim bolj dosledni, natančni in ponovljivi. Ta dokument opisuje, kako označiti elektroenergetsko zmogljivost vetrne turbine, kar zadeva izmerjeno krivuljo električne energije in ocenjeno vrednost AEP. Zagotavlja smernice o premislekih glede negotovosti v zvezi z elektroenergetsko zmogljivostjo vzorca preskušenih turbin glede na elektroenergetsko zmogljivost vseh turbin v vetrni elektrarni. Zagotavlja tudi smernice za vrednotenje kombinirane negotovosti za primer, ko se preskuša več turbin.
