Scope

The purpose of this document is to describe the processes and methods to ensure that wind energy resource measurements using cabin-mounted wind profiler lasers are carried out and reported consistently and based on best practices. This document does not specify the purpose or usage scenarios of wind energy resource measurements. However, it is expected that wind energy resource measurements will be used for some form of wind energy testing or resource assessment.
The scope of this document is limited to forward-looking cabin-mounted wind profiler lasers (i.e., those with the measurement volume located upstream of the wind turbine rotor).
This document is intended to apply to any type and brand of cabin-mounted wind profiler lasers. The methods and requirements provided in this document are independent of their model and type, and are designed to allow their application to new cabin-mounted laser devices.
This document aims to describe wind energy resource measurements using cabin-mounted wind profiler lasers, ensuring their quality is sufficient for use in power characteristic testing (according to GB/T 18451.2-2025). Users of this document are advised to consider that other usage scenarios may have specific requirements.
This document only provides guidelines for flat terrain and offshore measurements as defined in Appendix B of GB/T 18451.2-2025. Due to limited experience in preparing this document, it is not applicable to complex terrain applications.
This document does not address corrections for induced zones or blocking effects. If required by usage scenarios, users are responsible for making corrections to blocking effects or conducting uncertainty assessments themselves.
The purpose of this document is to provide guidance for wind energy resource measurements. Health, Safety, and Environmental (HSE) requirements are important (e.g., laser operation), but this document does not address these aspects.
