What is BS EN IEC 61400‑27-2 about?
BS EN IEC 61400‑27-2 is a part of multi-series standard IEC 61400. BS EN IEC 61400-27-2 deals with wind energy generation systems. It 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 specified in BS EN IEC 61400-27-2 are based on comparisons between measurements and simulations, but they are independent of the choice of software simulation tool.
Note 1: The validation procedures given in BS EN IEC 61400‑27-2 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.
Who is BS EN IEC 61400‑27-1 for?
BS EN IEC 61400‑27-1 on validation of electrical simulation models is useful for:
- Manufacturers and suppliers of wind turbine blades
- Designers of wind turbine blades
- Testing houses/ service/certification providers for wind turbine blades
- Entities dealing with wind energy generation systems
Why should you use BS EN IEC 61400‑27-1?
The increasing use of wind energy in power systems implies that Transmission System Operators (TSOs) and Distribution System Operators (DSOs) need to use dynamic models of wind power generation for power system stability studies.
BS EN IEC 61400‑27-1 discusses model validation procedures for electrical simulation models of wind turbines and wind power plants, which helps you in assessing the accuracy of the fundamental frequency response of wind power plant models and wind turbine models.
BS EN IEC 61400‑27-1 includes the validation procedures for wind turbine models focusing on fault ride-through capability and control performance. It gives you the procedure for validation of the generic positive sequence models as specified by global standards.
Users of BS EN IEC 61400‑27-2 can specify validation procedures for dynamic models, which can be applied in power system stability studies. It also gives you validation specifications for the positive sequence as well as negative sequence response of more detailed models developed by wind turbine manufacturers.
