<p>ISO 10816-21:2015 specifies the measurement and evaluation of mechanical vibration of wind turbines and their components by taking measurements on non-rotating parts. It applies to horizontal axis wind turbines with mechanical gearbox and rated generator output exceeding 200 kW and the following design and operational characteristics:</p>
<p>a) installation on supporting systems (tower and foundation) made of steel and/or concrete;</p>
<p>b) horizontal axis rotor with several rotor blades;</p>
<p>c) rotor bearing separate from or integrated into the gearbox;</p>
<p>d) generators driven via gearbox;</p>
<p>e) generators of the synchronous or asynchronous type (mostly equipped with 4-pole generator);</p>
<p>f) generators with only a fixed pole number or which are pole-changeable for speed adjustment;</p>
<p>g) output control by rotor blades (pitch or stall wind turbines);</p>
<p>h) generator coupled to the power grid via converter or directly.</p>
