Wind energy generation systems - Part 21-1: Measurement and assessment of electrical characteristics - Wind turbines
IEC 61400-21-1:2019 includes: · definition and specification of the quantities to be determined for characterizing the electrical characteristics of a grid-connected wind turbine; · measurement procedures for quantifying the electrical characteristics; · procedures for assessing compliance with electrical connection requirements, including estimation of the power quality expected from the wind turbine type when deployed at a specific site. The measurement procedures are valid for single wind turbines with a three-phase grid connection. The measurement procedures are valid for any size of wind turbine, though this part of IEC 61400 only requires wind turbine types intended for connection to an electricity supply network to be tested and characterized as specified in this part of IEC 61400. This first edition cancels and replaces the second edition of 61400-21 published in 2008. This edition includes the following new items with respect to 61400-21: a) frequency control measurement; b) updated reactive power control and capability measurement, including voltage and cos φ control; c) inertia control response measurement; d) overvoltage ride through test procedure; e) updated undervoltage ride through test procedure based on Wind Turbine capability; f) new methods for the harmonic assessment.

Systèmes de génération d'énergie éolienne - Partie 21-1: Mesurage et évaluation des caractéristiques électriques - Éoliennes
l'IEC 61400-21-1:2019 comprend: · la définition et la spécification des grandeurs à déterminer pour caractériser les caractéristiques électriques d'une éolienne connectée à un réseau; · les procédures de mesure pour quantifier les caractéristiques électriques; · les procédures pour évaluer la conformité aux exigences de raccordement électrique, y compris l'estimation de la qualité de puissance attendue d'un type d'éolienne, une fois déployée sur un site spécifique. Les procédures de mesure sont valables pour les éoliennes individuelles avec un raccordement triphasé au réseau. Les procédures de mesure sont valables pour n'importe quelle taille d'éolienne; toutefois, la présente partie de l'IEC 61400 exige uniquement des types d'éoliennes prévues pour le raccordement à un réseau d'alimentation électrique, qui sont donc à soumettre aux essais et à caractériser comme spécifié dans la présente partie de l'IEC 61400. Cette première édition annule et remplace la deuxième édition de l'IEC 61400-21 parue en 2008. Cette édition inclut les nouveaux éléments suivants par rapport à l'IEC 61400-21: a) mesure de contrôle de fréquence; b) contrôle actualisé de la puissance réactive et de la mesure de la capacité, y compris le contrôle de la tension et contrôle du cos φ; c) mesure de la réponse du contrôle d'inertie; d) procédure d'essai du passage de surtension; e) procédure d'essai du maintien de l'alimentation en sous-tension en fonction de la capacité des éoliennes actualisée; f) nouvelles méthodes pour l'évaluation de l'harmonique.
Sistemi za proizvodnjo energije na veter - 21-1. del: Merjenje in ocenjevanje električnih karakteristik - Vetrne turbine (IEC 61400-21-1:2019)
Ta del standarda IEC 61400 vključuje:
• opredelitev in specifikacijo količin, ki jih je treba določiti za opis električnih karakteristik vetrne turbine, povezane z omrežjem;
• merilne postopke za količinsko opredelitev električnih karakteristik;
• postopke za oceno skladnosti z zahtevami za električno povezavo, vključno z oceno pričakovane kakovosti električne energije glede na vrsto vetrne turbine, ko je nameščena na določenem mestu.
Postopki merjenja veljajo za enojne vetrne turbine s trifaznim omrežnim priključkom. Postopki merjenja veljajo za poljubno velikost vetrne turbine, čeprav ta del standarda IEC 61400 zahteva le preskus in karakterizacijo vetrnih turbin v skladu s tem delom standarda IEC 61400, ki so namenjene za povezavo z električnim omrežjem.
Izmerjene karakteristike veljajo za specifično konfiguracijo in način delovanja ocenjevane platforme vetrnih turbin. Če izmerjena lastnost temelji na regulacijskih parametrih in se na podlagi spremembe te lastnosti spremeni delovanje vetrne turbine, je to navedeno v poročilu o preskusu. Primer: Zaščita omrežja, pri kateri raven odklopa temelji na parametru in preskus preveri zgolj pravilno delovanje zaščite, ne pa specifične ravni.
Postopki merjenja so zasnovani tako, da so čim manj odvisni od mesta namestitve, tako da je električne karakteristike, izmerjene na primer na preskusnem mestu, mogoče obravnavati kot reprezentativne tudi za druga mesta.
Ta dokument je namenjen preskušanju vetrnih turbin; vsi postopki, meritve in preskusi v zvezi z vetrnimi elektrarnami so zajeti v standardu IEC 61400-21-2.
Postopki za oceno električnih karakteristik veljajo za vetrne turbine s priključkom na PCC v elektroenergetskih sistemih z nespremenljivo frekvenco omrežja.
OPOMBA:
V tem dokumentu se uporabljajo naslednji izrazi za napetost v omrežju:
– nizka napetost (LV) označuje Un ≤ 1 kV;
– srednja napetost (MV) označuje 1 kV < Un ≤ 35 kV;
– visoka napetost (HV) označuje 35 kV < Un ≤ 220 kV;
– zelo visoka napetost (EHV) označuje Un > 220 kV.
