3MW series wind turbine generator set
The SL3000 series wind turbine adopts a mature and reliable doubly fed power generation technology route and a compact transmission chain, with multiple innovations such as self maintenance of offshore large components, salt spray corrosion prevention, and modular design on land. The impeller diameter covers 90/105/113/121/130/137/141/146m, and the hub center height is 80/90/95/100/110m, which can meet the installation needs of various areas such as land, sea, and intertidal zones. The series of units have been certified by GL, China Jianheng, and other authoritative certification agencies both domestically and internationally.
After years of batch operation and testing, the SL3000 series units have mature and reliable technology, and operate stably and efficiently.
Based on the massive operating data and experience of the first and second generation SL3000 series wind turbines, the overall layout, system structure, intelligent control, power generation performance, and other aspects of the turbines have been comprehensively optimized and improved. A new third-generation SL3000/14X series large blade diameter wind turbine product platform has been launched.
