5-6MW series wind turbine generator set
SL5000/SL6000 is a new platform for large megawatt intelligent offshore wind turbines developed by Huarui Wind Electric for wind resources and climate characteristics in coastal areas of China. It has a power level of 5-6MW, an impeller diameter of 139-170m, and multiple patented technologies (ZL201210434533.1, ZL201110240459.5, ZL200910241617.1, etc.), which can adapt to harsh environmental conditions such as high typhoons, heavy salt spray, and ultra-high temperatures. The stability and reliability of the unit have been verified by 6 years of actual operation in offshore wind farms.
The power generation performance indicators and reliability of the SL5000/170IIIB offshore wind turbine developed based on the above platform are at the international advanced level.
