Retrieved 14 March The standard concerns most aspects of the turbine life from site conditions before construction, to turbine components being tested, [1] assembled iec 61400-3 operated. National Renewable Energy Laboratory participates in IEC standards development work, [3] [6] and tests equipment according to these standards.

Iec 61400-3 the wind speed increases with increasing height. Because the fatigue loads of a number of major components in a wind turbine are mainly caused by turbulence, the knowledge of how turbulent a site is of crucial importance.

In complex terrain the wind profile is not a irc increase and additionally a separation of the flow might occur, leading to heavily increased turbulence. In Canada, iec 61400-3 previous national standards were outdated and impeded the wind industry, and they were updated and harmonized with by the Canadian Iec 61400-3 Association with several modifications. During the iec 61400-3 and design phase assumptions are made about the wind climate that the wind turbines will be exposed to.
