BS EN IEC 61400 series covers energy generation systems. BS EN IEC 61400‑26‑1 is one of the parts of a series of documents that defines an information model from which time-based, and production-based availability indicators for services can be derived and reported.
BS EN IEC 61400 provides best practice guidance and specifications on categories, which unambiguously describe how data is used to characterize and categorize the operation. The information model specifies category priority for discrimination between possible concurrent categories. Further, the model defines entry and exit criteria to allocate fractions of time and production values to the proper information category.
BS EN IEC 61400‑26‑1 is useful for the following entities related to wind energy generation systems:
The intention of BS EN IEC 61400‑26‑1 International Standard is to define a common basis for the exchange of information on availability metrics between stakeholders in the wind power generation business.
The purpose of BS EN IEC 61400‑26‑1 is to provide standardized metrics that can be used to create and organize methods for availability calculation and reporting according to the user’s needs.
BS EN IEC 61400‑26‑1 can be applied to any number of WTGSs, whether represented by an individual turbine, a fleet of wind turbines, a wind power station, or a portfolio of wind power stations. A wind power station is typically made up of all WTGSs, functional services and balance of plant elements as seen from the point of common coupling.
A degree of uncertainty is inherent in both the measurement of a power curve and the calculation of potential energy production. The stakeholders should agree upon acceptable uncertainty parameters.
