This part of IEC 61400 specifies procedures for validation of electrical simulation models for
wind turbines and wind power plants, intended to be used in power system and grid stability
analyses. The validation procedures are based on the tests specified in IEC 61400-21 (all
parts). The validation procedures are applicable to the generic models specified in
IEC 61400-27-1 and to other fundamental frequency wind power plant models and wind
turbine models.

This document presents measurement procedures that enable noise emissions of a wind turbine to be characterised. This involves using measurement methods appropriate to noise emission assessment at locations close to the machine, in order to avoid errors due to sound propagation, but far away enough to allow for the finite source size. The procedures described are different in some respects from those that would be adopted for noise assessment in community noise studies. They are intended to faci...view more
