ISO/TC 108/SC 2 Measurement and evaluation of mechanical vibration and shock as applied to machines, vehicles and structures
International Standard
17.160 Vibrations, shock and vibration measurements
Published
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:
a) installation on supporting systems (tower and foundation) made of steel and/or concrete;
b) horizontal axis rotor with several rotor blades;
c) rotor bearing separate from or integrated into the gearbox;
d) generators driven via gearbox;
e) generators of the synchronous or asynchronous type (mostly equipped with 4-pole generator);
f) generators with only a fixed pole number or which are pole-changeable for speed adjustment;
g) output control by rotor blades (pitch or stall wind turbines);
h) generator coupled to the power grid via converter or directly.
