Reference Designation Standards for Wind Power Systems – Wind Turbine Generator (RDS for WTG)
The aim of the Wind Industry Guideline for Reference Designation Standards for Wind Power Systems – Wind Turbine Generator (RDS for WTG) is to establish a common understanding and alignment in the use of reference designation standards within the wind power sector. The guideline includes a functional, location, and product-based breakdown of the wind turbine.
The Purpose
Reference Designation is a means of applying unambiguous identification to all parts of a system. A reference designator combines letters and numbers to identify the various features and components on drawings, diagrams, and parts lists. It’s the basis for standardized communication between all those involved in planning, engineering, construction, and operation.
The wind industry application guideline is based on ISO/IEC 81346-10:2022, Industrial systems, installations and equipment and industrial products – Structuring principles and reference designation – Part 10: Power supply plants, and is designed to integrate with other parts of the 81346 series.
