BS ISO 10816-21:2015规定了风的机械振动的测量和评估 通过在非旋转部件上进行测量的涡轮机及其部件。它适用于水平方向 axis风力涡轮机，配备机械齿轮箱，额定发电机输出超过200 kW，以及 以下设计和操作特点:安装在钢和/或混凝土制成的支撑系统（塔架和基础）上；带有多个转子叶片的水平轴转子；与齿轮箱分离或集成在齿轮箱中的转子轴承；通过齿轮箱驱动的发电机；同步或异步发电机（主要配备四极发电机）；只有固定极数或可变极调速的发电机；转子叶片（变桨或失速风力涡轮机）的输出控制； 发电机通过转换器或直接连接到电网。ISO 10816的本部分建议在连续负载运行时评估振动的区域。 然而，在大多数情况下，这些评估区边界可能不适合早期检测 有很多缺点。ISO 10816的这一部分没有规定区域边界的振动值，因为 是否没有足够的数据可用于涵盖全球范围的风力涡轮机 根据ISO 10816的这一部分。然而，附件A给出了评估区边界，仅供参考 用于陆上风力涡轮机。这些区域边界基于约1000个风场的振动数据 额定发电机输出高达3 MW的涡轮机。它们有助于促进双方的讨论 用户和制造商。 海上风力涡轮机的评估区域边界尚不可用。交叉引用:ISO 2041ISO 2954ISO 2631-1ISO 4866ISO 5348ISO 8041ISO 8579-2ISO 13372ISO 13373-1ISO 13373-2ISO 16079IEC 60034-14IEC 60050-415IEC 61400-4IEC/TS 61400-13DIN 4150-3VDI 3832VDI 3839第1部分:2001-03VDI 3839第2部分购买本文件时提供的所有当前修改件均包含在购买本文件中。

BS 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:installation on supporting systems (tower and foundation) made of steel and/or concrete;horizontal axis rotor with several rotor blades;rotor bearing separate from or integrated into the gearbox;generators driven via gearbox;generators of the synchronous or asynchronous type (mostly equipped with 4-pole generator);generators with only a fixed pole number or which are pole-changeable for speed adjustment;output control by rotor blades (pitch or stall wind turbines);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 detection of faults. This part of ISO 10816 does not specify vibration values for the zone boundaries because there are insufficient data available for the complete range of wind turbines in the worldwide fleet covered by this part of ISO 10816. However, for information only, Annex A presents evaluation zone boundaries for onshore wind turbines. These zone boundaries are based on vibration data from about 1 000 wind turbines with rated generator output up to 3 MW. They can be helpful in facilitating discussion between users and manufacturers. Evaluation zone boundaries for offshore wind turbines are not yet available.Cross References:ISO 2041ISO 2954ISO 2631-1ISO 4866ISO 5348ISO 8041ISO 8579-2ISO 13372ISO 13373-1ISO 13373-2ISO 16079IEC 60034-14IEC 60050-415IEC 61400-4IEC/TS 61400-13DIN 4150-3VDI 3832VDI 3839 part 1:2001-03VDI 3839 part 2All current amendments available at time of purchase are included with the purchase of this document.
