The Scope of the IEC 61400-16 standard is to establish a common content, terminology and structure applicable to all wind turbine OEMs for the sharing of wind turbine power curves and associated information (3.1.17) (for background, see Annex A) in a machine-readable format.
Throughout the remainder of this document, this common structure is defined by a Power Curve Schema. A JSONSchema (3.1.11) defines how to structure and populate a specific JSON (3.1.10) document (for more detail, see Annex B), and can be used for automated data validation.
The power curves and associated information (3.1.17) communicated within a JSON (3.1.10) document (which is compliant with the Power Curve Schema) covers:
– Document metadata
– The turbine model characteristics (3.1.25)
– Design basis information
– Operating mode information, where each mode contains
• Power (as a function of wind speed and optionally other parameters)
• Thrust (as a function of wind speed and optionally other parameters)
• Optional acoustic emissions (as a function of wind speed and other parameters) – Power de-rating details
JSON documents containing power curves and associated information shall be based on the JavaScript Object Notation ("JSON") format ISO/IEC 21778:2017 and shall follow the specifications in this document (i.e. conform to the Power Curve Schema).
Security, document integrity (e.g. digital signing) and distribution of data rests with the authors and users of the data and is outside the scope of the standard.
Measured power curves can be represented using the Power Curve Schema but details relating to the measurement configuration, statistics of the measurement results and other details specific to power performance measurements cannot be captured.
This standard does not specify document generation, display, checking or publishing processes
which may be achieved using third party or custom tools (e.g. automated PDF report generation from the JSON data).
