Unique self-maintenance system makes large component (gearbox,generatoretc) replacements possible without large-scale installation vessel; Technologies including multi-stage filtration system and temperature & humidity control are applicable to marine atmosphere and bring better anticorrosion performance; Compact drive train and load distribution technologies efficiently distribute the load and power transmission and improve turbine reliability and life time; Hydraulic support for gearbox has the advantage of good vibration reduction with simple and reliable structure; Single-line lubrication system for main bearing, pitch bearing and yaw bearing has the advantage of well lubrication and reliability; Reliable nature air cooling system for gearbox and generator has the advantage of less power consumption, noise and maintenance; Main electrical equipments including converter, transformer and switch gear are located inside the foundation platform. This layout has minimum vibration to the equipment with convenient maintenance; Leading technologies including offshore load optimization and control, anti-typhoon control strategy and turbine operation and control under complicated marine environment significantly reduce the turbine load and improve t urbine reliability; Wind farm and turbine monitoring system with online detection, fault diagnosis and customization makes real time monitoring and advance warning; Smart operation & maintenance are achieved with less maintenance cost; Smart technologies including pitch control, fine yaw control, soft cut-out control, adaptive energy acquisition and grid connection optimization control maximize power generation and environment suitability and bring maximum profit ability; Leading technologies including smart fault self-diagnosis a

SL5000/SL6000 is a new platform of large-scale intelligent offshore wind turbines developed by

Sinovel basing on the wind resources and climate characteristics of China's coastal areas. The power

of machine is in the range of 5 - 6MW and the rotor diameter is from 139 to 170m. This series has

many patented technologies and can adapt to severe environmental conditions such as typhoon,

heavy salted air and ultra-high temperature etc. The machine¡¯s stability and reliability have been

subject to the actual operational experience of the offshore wind farm for 8 years. Basing on the

above-mentioned platform, the power generation performance index and reliability of the SL5000¢óB

offshore wind turbine are at the international advanced level.
