Wind energy generation systems - Part 27-2: Electrical simulation models - Model validation
IEC 61400-27-2:2020 specifies procedures for validation of electrical simulation models for wind turbines and wind power plants, intended to be used in power system and grid stability analyses. The validation procedures are based on the tests specified in IEC 61400-21 (all parts). The validation procedures are applicable to the generic models specified in
IEC 61400-27-1 and to other fundamental frequency wind power plant models and wind turbine models.
The validation procedures for wind turbine models focus on fault ride through capability and control performance. The fault ride through capability includes response to balanced and unbalanced voltage dips as well as voltage swells. The control performance includes active power control, frequency control, synthetic inertia control and reactive power control. The validation procedures for wind turbine models refer to the tests specified in IEC 61400-21-1. The validation procedures for wind turbine models refer to the wind turbine terminals.
Systèmes de génération d'énergie éolienne - Partie 27-2: Modèles de simulation électrique - Validation des modèles
IEC 61400-27-2:2020 spécifie des procédures de validation des modèles de simulation électrique pour les éoliennes et les centrales éoliennes, destinées à être utilisées dans des analyses de stabilité du réseau d'énergie électrique et du réseau de distribution. Les procédures de validation reposent sur les essais spécifiés dans l'IEC 61400-21 (toutes les parties). Les procédures de validation sont applicables aux modèles génériques spécifiés dans l’IEC 61400-27-1 et aux autres modèles de centrales éoliennes et d’éoliennes à fréquence fondamentale.
Les procédures de validation des modèles d'éoliennes se concentrent sur la capacité d’alimentation continue par défaut et les performances de commande. La capacité d’alimentation continue par défaut comprend la réponse aux creux de tension équilibrés et déséquilibrés, ainsi qu’aux hausses de tension. Les performances de commande comprennent la commande de puissance active, la commande de fréquence, la commande d’inertie synthétique et la commande de puissance réactive. Les procédures de validation applicables aux modèles d’éoliennes se rapportent aux essais spécifiés dans l’IEC 61400‑21‑1. Les procédures de validation applicables aux modèles d’éoliennes se rapportent aux bornes de l'éolienne.
