Short description
The VDI 3834 series of guidelines provides information about the measurement and evaluation of the mechanical vibration of wind turbines and their components. It applies to WTs with rated generator outputs exceeding 100 kW and the following design and operation characteristics: siting onshore or off the coast (offshore), installation on supporting systems (tower and foundation) made of steel and concrete horizontal-axis rotor with several rotor blades, rotor bearing separate from or integrated into the gearbox, generators driven via gearbox or direct driven, generators of the synchronous or asynchronous type, generators with only a fixed pole number or which are pole-changeable for speed adjustment, output control by rotor blade adjustment (pitch) or stall, generator coupled to the power grid via converter or directly. The present guideline applies to Group 1 WTs. In Section 5 will be found the guide values for evaluating vibration in the stable generating range, but for the time being only for nominal outputs of ≤3 MW or less.
