Wind turbines - Part 27-1: Electrical simulation models - Wind turbines

IEC 61400-27-1:2015 specifies dynamic simulation models for generic wind turbine topologies/concepts/configurations on the market. It defines the generic terms and parameters with the purpose of specifying the electrical characteristics of a wind turbine at the connection terminals. The models are described in a modular way which can be applied for future wind turbine concepts. The dynamic simulation models refer to the wind turbine terminals. The validation procedure specified in IEC 61400-27-1 focuses on the IEC 61400-21 tests for response to voltage dips, reference point changes and grid protection.

Windenergieanlagen - Teil 27-1: Elektrische Simulationsmodelle - Windenergieanlagen

Eoliennes - Partie 27-1: Modèles de simulation électrique - Eoliennes

L'IEC 61400-27-1:2015 spécifie des modèles de simulation dynamiques pour les topologies/concepts/configurations génériques d'éoliennes disponibles sur le marché. Elle définit les termes et paramètres génériques ayant pour objet de spécifier les caractéristiques électriques d'une éolienne au niveau des bornes de connexion. Les modèles sont décrits de manière modulaire et peuvent être appliqués aux futurs concepts d'éoliennes. Les modèles de simulation dynamiques se rapportent aux bornes de l'éolienne. La procédure de validation spécifiée dans l'IEC 61400-27-1 se concentre sur les essais de l'IEC 61400-21 pour la réponse aux creux de tension, les variations de la valeur de consigne et la protection du réseau.

Vetrne turbine - 27-1. del: Električni simulacijski modeli - Vetrne turbine

IEC 61400-27 določa standardne električne simulacijske modele za vetrne turbine in vetrne elektrarne. Predpisani modeli so simulacijski modeli pozitivnega zaporedja v časovnem območju, namenjeni za uporabo pri analizah stabilnosti napajalnega sistema in mreže. Modeli se uporabljajo za dinamične simulacije kratkotrajne stabilnosti v napajalnih sistemih. IEC 61400-27 vključuje postopke za overjanje predpisanih električnih simulacijskih modelov. Postopek za overjanje za IEC 61400-27 temelji na preskusih, določenih v standardu IEC 61400-21.
IEC 61400-27 vključuje dva dela z naslednjima področjema uporabe:
– IEC 61400-27-1 določa dinamične simulacijske modele za splošne topologije/koncepte/konfiguracije vetrnih turbin na tržišču. IEC 61400-27-1 določa splošne pogoje in parametre za namene določitve električnih značilnosti vetrne turbine pri povezovalnih priključkih. Modeli so opisani na modularen način, ki ga je mogoče uporabiti za bodoče koncepte vetrnih turbin. Dinamični simulacijski modeli se nanašajo na priključke turbine. Postopek za overjanje, določen v standardu IEC 61400-27-1, se osredotoča na preskuse odzivov na upade napetosti, spremembe referenčnih točk in zaščito mreže iz standarda IEC 61400-21.
– IEC 61400-27-2 določa dinamične simulacijske modele za splošne topologije/konfiguracije na tržišču, vključno z nadzorom vetrne elektrarne in pomožno opremo. IEC 61400-27-2 poleg tega določa metodo za ustvarjanje modelov za bodoče konfiguracije vetrnih elektrarn. Modeli vetrnih elektrarn temeljijo na modelih vetrnih turbin, predpisanih v standardu IEC 61400-27-1. Električni simulacijski modeli, predpisani v standardu IEC 61400-27, niso odvisni od nobenega programskega orodja za simulacije.
