(Main)Wind energy generation systems - Part 12-1: Power performance measurements of electricity producing wind turbines
Wind energy generation systems - Part 12-1: Power performance measurements of electricity producing wind turbines
IEC 61400-12-1:2022 specifies a procedure for measuring the power performance characteristics of a single wind turbine and applies to the testing of wind turbines of all types and sizes connected to the electrical power network. In addition, this document defines a procedure to be used to determine the power performance characteristics of small wind turbines (as defined in IEC 61400-2) when connected to either the electric power network or a battery bank. This document defines a measurement methodology that requires the measured power curve and derived energy production figures to be supplemented by an assessment of uncertainty sources and their combined effects. This third edition of IEC 61400-12-1 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.
Windenergieanlagen - Teil 12-1: Messung des Leistungsverhaltens von Windenergieanlagen
Systèmes de génération d'énergie éolienne - Partie 12-1: Mesurages de performance de puissance des éoliennes de production d'électricité
L'IEC 61400-12-1:2022 spécifie une procédure de mesure des caractéristiques de performance de puissance d'une éolienne simple et s'applique aux essais d'éoliennes, de tous types et de toutes tailles, raccordées au réseau électrique. En outre, le présent document définit une procédure à utiliser pour déterminer les caractéristiques de performance de puissance des petits aérogénérateurs (comme cela est défini dans l'IEC 61400-2) raccordés soit au réseau électrique, soit à un banc de batteries. Le présent document définit une méthodologie de mesure qui exige que les valeurs de la courbe de puissance mesurée et de la production d'énergie déduite soient complétées par une évaluation des sources d'incertitude et de leurs effets associés. La présente troisième édition de l’IEC 61400-12-1 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.
