Wind turbines - Part 11: Acoustic noise measurement techniques

IEC 61400-11:2012(E) presents measurement procedures that enable noise emissions of a wind turbine to be characterised. This involves using measurement methods appropriate to noise emission assessment at locations close to the machine, in order to avoid errors due to sound propagation, but far away enough to allow for the finite source size. The procedures described are different in some respects from those that would be adopted for noise assessment in community noise studies. They are intended to facilitate characterisation of wind turbine noise with respect to a range of wind speeds and directions. Standardisation of measurement procedures will also facilitate comparisons between different wind turbines. This new edition constitutes a technical revision, introducing new principles for data reduction procedures.

Eoliennes - Partie 11: Techniques de mesure du bruit acoustique

l’IEC 61400-11:2012 spécifie les procédures de mesure qui permettent de caractériser les émissions sonores d’une éolienne. Cette démarche implique l’utilisation de méthodes de mesure appropriées à l’évaluation des émissions sonores à des emplacements proches de la machine, afin d’éviter les erreurs dues à la propagation du son, mais toutefois suffisamment éloignés pour permettre de déterminer la dimension des sources finies. Les procédures décrites sont différentes à certains égards de celles qui seraient adoptées pour l’évaluation du bruit dans le cadre des études portant sur le bruit ambiant. Ces procédures sont destinées à faciliter la caractérisation du bruit émis par une éolienne par rapport à une plage donnée de vitesses et de directions du vent. La normalisation des procédures de mesure facilite également les comparaisons entre différentes éoliennes. Cette nouvelle édition constitue une révision technique, introduisant de nouveaux principes concernant les procédures de traitement des données.

Vetrne turbine - 11. del: Tehnike merjenja hrupa

Ta del standarda IEC 61400 predstavlja postopke merjenja, ki omogočajo opredelitev emisij hrupa vetrnih turbin. To vključuje načine merjenja, ki so primerni za ocenjevanje emisij hrupa na lokacijah, ki so dovolj blizu naprave, da bi se izognili napakam zaradi širjenja zvoka na prostem, vendar dovolj daleč, da je mogoče pridobiti končno velikost vzorca. Nekateri vidiki opisanih postopkov so drugačni od postopkov, ki se uporabljajo za ocenjevanje hrupa v študijah hrupa v okolici. Namenjene so opredelitvi hrupa vetrnih turbin, pri čemer upoštevajo razpon hitrosti in smeri vetra. Standardizacija merilnih postopkov bo omogočila tudi primerjave različnih vetrnih turbin. Postopki predstavljajo metodologijo, ki bo omogočila usklajeno in pravilno opredelitev emisij hrupa vetrnih turbin. Ti postopki vključujejo naslednje:
• lokacijo položajev akustičnega merjenja;
• zahteve za pridobitev akustičnih, meteoroloških in drugih povezanih podatkov o delovanju vetrnih turbin;
• analizo pridobljenih podatkov in vsebino za poročila ter
• definicijo posebnih parametrov akustičnih emisij in povezanih deskriptorjev, ki se uporabljajo za izvajanje okoljskih ocen.
Ta mednarodni standard ni omejen na določene velikosti ali vrste vetrnih turbin. Postopki, ki so opisani v tem standardu, omogočajo temeljit opis emisij hrupa iz vetrnih turbin. Metoda za majhne vetrne turbine je opisana v dodatku F.
