This publication is a technical report that provides guidance for manufacturers, vendors, purchasers and users of wind turbines. It covers the application of Electromagnetic Compatibility (EMC) standards.
Manufacturers and vendors of wind turbines should refer also to Article 10 of the Council Directive 89/336/EEC of 3 May 1989 (the Electromagnetic Compatibility [EMC] Directive), which covers such matters as declarations of conformity and CE marks.
This report provides guidance on requirements for the electromagnetic compatibility of wind turbines of all sizes, to assist with achieving compliance with EMC standards. This report includes guidance on emissions, and for immunity to external disturbances.
Safety related aspects are not included in this technical report. They are the subject of relevant parts of EN 61400.
PD CLC/TR 50373 is applicable to electromagnetic emissions and immunity, both conducted and radiated, in the range 0 Hz to 400 GHz (although generally EMC standards do not at present contain test methods or limits at frequencies above 1 GHz). Fault conditions are not taken into account.
The report also provides guidance for wind turbine installations (wind farms or single machines).
The electromagnetic compatibility of components within the wind turbine (i.e. within enclosed parts of the wind turbine, which may include the hub, nacelle and tubular tower) with each other is solely a matter for the wind turbine manufacturer.
The physical impact of the structure on the reception of radio services in the vicinity needs to be considered as a separate issue, and is not dealt with in this technical report. It should be noted that although experience to date has shown that physical interference to broadcasting services has caused the majority of complaints, wind turbines are capable of interfering with all radio services to some extent.
