Wind energy generation systems - Part 50-3: Use of nacelle-mounted lidars for wind measurements

The purpose of this part of IEC 61400 is to describe procedures and methods that ensure that wind measurements using nacelle-mounted wind lidars are carried out and reported consistently and according to best practice. This document does not prescribe the purpose or use case of the wind measurements. However, as this document forms part of the IEC 61400 series of standards, it is anticipated that the wind measurements will be used in relation to some form of wind energy test or resource assessment. The scope of this document is limited to forward-looking nacelle-mounted wind lidars (i.e. the measurement volume is located upstream of the turbine rotor). This document aims to be applicable to any type and make of nacelle-mounted wind lidar. The method and requirements provided in this document are independent of the model and type of instrument, and also of the measurement principle and should allow application to new types of nacelle-mounted lidar. This document aims to describe wind measurements using nacelle-mounted wind lidar with sufficient quality for the use case of power performance testing (according to IEC 61400-12-1:2017). Readers of this document should consider that other use cases may have other specific requirements. This document only provides guidance for measurements in flat terrain and offshore as defined in IEC 61400-12-1:2017, Annex B. Application to complex terrain has been excluded from the scope due to limited experience at the time of writing this document. Corrections for induction zone or blockage effects are not included in the scope of this document. However, such correction or uncertainty estimation due to blockage effects may be applied if required by the use case, under the responsibility of the user. The purpose of this document is to provide guidance for wind measurements. HSE requirements (e.g. laser operation) are out of the scope of this document although they are important.

Windenergieanlagen - Teil 50-3: Verwendung von auf der Gondel montierten LiDARs für Windmessungen

Systèmes de génération d'énergie éolienne - Partie 50-3: Utilisation de lidars montés sur nacelle pour le mesurage du vent

IEC 61400-50-3:2022 décrit les procédures et les méthodes qui permettent de s'assurer que les mesurages du vent à l'aide de lidars montés sur nacelle sont réalisés et consignés de manière cohérente et conformément aux meilleures pratiques. Le présent document ne précise pas l'objet ou le cas d'utilisation des mesurages du vent. Toutefois, le présent document faisant partie de la série de normes IEC 61400, il est envisagé que les mesurages du vent soient utilisés dans le cadre d'essais relatifs à l'énergie éolienne ou d'une évaluation des ressources. Le domaine d'application du présent document se limite aux lidars montés sur nacelle à l'avant (c'est-à-dire que le volume de mesure est situé en amont du rotor de l'éolienne). Le présent document a pour objectif de décrire le mesurage du vent à l'aide d'un lidar monté sur nacelle de qualité suffisante pour être utilisé dans le cadre d'essais de performance de puissance (conformément à l'IEC 61400-12-1:2017).

Sistemi za proizvodnjo energije na veter - 50-3. del: Uporaba na gondolo pritrjenih merilnikov LiDAR za meritve vetra (IEC 61400-50-3:2022)

Namen tega dela standarda IEC 61400 je opisati postopke in metode, s katerimi se zagotovi, da se meritve vetra z uporabo na gondolo pritrjenih merilnikov vetra LiDAR izvajajo in se o njih poroča dosledno ter v skladu z najboljšo prakso. Ta dokument ne predpisuje namena ali primera uporabe meritev vetra. Ker pa je ta dokument del skupine standardov IEC 61400, se pričakuje, da bodo meritve vetra uporabljene v povezavi z določeno obliko preskusa energije na veter ali oceno virov. Področje uporabe tega dokumenta je omejeno na merilnike vetra LiDAR, ki so pritrjeni na gondolo in usmerjeni naprej (tj. količina za merjenje je pred rotorjem turbine). Namen tega dokumenta je uporabnost za vse tipe in znamke na gondolo pritrjenih merilnikov vetra LiDAR. Metoda in zahteve v tem dokumentu so neodvisne od modela oziroma vrste instrumenta ter načela merjenja in naj bi omogočale uporabo za nove tipe na gondolo pritrjenih merilnikov LiDAR. Namen tega dokumenta je opisati meritve vetra z uporabo na gondolo pritrjenih merilnikov vetra LiDAR z ustrezno kakovostjo za primer uporabe preskušanja zmogljivosti (v skladu s standardom IEC 61400-12-1:2017). Uporabniki tega dokumenta naj upoštevajo, da lahko za druge primere uporabe veljajo druge posebne zahteve. Ta dokument podaja smernice samo za meritve na ravnem terenu in na morju, kot je opredeljeno v standardu IEC 61400-12-1:2017, dodatek B. Uporaba za razgibani teren je bila zaradi omejenih izkušenj v času pisanja tega dokumenta izključena s področja uporabe. Popravki za induktivno območje ali učinke blokade ne spadajo na področje uporabe tega dokumenta. Vendar pa se lahko na odgovornost uporabnika tak popravek ali ocena negotovosti zaradi učinkov blokade uporabi, če to zahteva primer uporabe. Namen tega dokumenta je podati smernice za meritve vetra. Zahteve HSE (npr. lasersko delovanje), ne spadajo na področje uporabe tega dokumenta, čeprav so pomembne.
