Annotation

Scope and application

The recommended practice is applicable to all types of wind turbines (e.g. direct drive concepts, doubly-fed induction generators, low and high power output ratings, horizontal and vertical axis installations, with or without power converters) designed according to IEC 61400-1.

The recommended practice is applicable to the design, manufacturing, installation and testing of the wind turbines’ electrical systems. This mainly refers to:

rotating electrical machines

power transformers

frequency converters

low-voltage switchgears, control gears and switchboards

high-voltage switchgears

lightning protection, earthing and bonding

electrical equipment for measurement and control use

cables, lines and accessories

safety-related parts of the control system

uninterruptible power systems (UPS)

interconnection of electrical equipment

installation of the wind turbine and its components and systems.

Wind turbines and their electrical components and systems shall be designed concerning EMC as to:
