标准范围

This part of ISO 10816 specifies the measurement and evaluation of mechanical vibration of windturbines and their components by taking measurements on non-rotating parts. It applies to horizontalaxis wind turbines with mechanical gearbox and rated generator output exceeding 200 kW and thefollowing 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.This part of ISO 10816 recommends zones for evaluating the vibration at continuous load operation.However, in most cases, these evaluation zone boundaries might not be suitable for the early detectionof faults. This part of ISO 10816 does not specify vibration values for the zone boundaries because thereare insufficient data available for the complete range of wind turbines in the worldwide fleet coveredby this part of ISO 10816. However, for information only, Annex A presents evaluation zone boundariesfor onshore wind turbines. These zone boundaries are based on vibration data from about 1 000 windturbines with rated generator output up to 3 MW. They can be helpful in facilitating discussion betweenusers and manufacturers. Evaluation zone boundaries for offshore wind turbines are not yet available.Although the type and implementation of broad-band vibration monitoring for wind turbines isaddressed, this part of ISO 10816 does not apply to diagnostics or fault detection by condition monitoringof wind turbines.
