Anotation

scope of this part of IEC 61400 is to define a framework for assessment and reporting of the site suitability/wind turbine suitability conditions for both onshore and offshore (fixed and floating) wind power plants. This includes:
a) definition, measurement, and prediction of the long-term meteorological and wind flow characteristics at the site;
b) integration of the long-term meteorological and wind flow characteristics with wind turbine and balance-of-plant characteristics;
c) characterizing environmental extremes and other relevant plant design drivers;
d) addressing documentation and reporting requirements to help ensure the traceability of the assessment processes.
The framework is defined such that applicable national norms are considered and industry best practices are utilized. This framework defines the minimum set of parameters. Additional parameters may be used if needed.
The meteorological and wind flow characteristics addressed in this document relate to wind conditions, where parameters such as wind speed, wind direction, turbulence intensity, wind shear, inflow angle, air density or air temperature are included to the extent that they affect the structural integrity of a wind turbine.
According to IEC 61400-1, IEC 61400-3-1 and IEC TS 61400-3-2, site specific conditions are wind conditions, marine conditions, other environmental conditions, soil conditions and electrical conditions. All of these site-specific conditions other than site specific wind conditions and related atmospheric variables addressed herein are out of scope for this document.
This document is framed to complement and support the scope of related IEC 61400 series by defining environmental input conditions. It is not intended to supersede the design and suitability requirements presented in those documents. Specific analytical and modelling procedures as described in IEC 61400-1, IEC 61400-2, IEC 61400-3-1 and IEC TS 61400-3-2 are excluded from the scope of this document
