Wind Turbine Generator System (WTGS) Platform
This WTGS boasts the world’s leading semi-direct drive compact transmission technology and onshore WTGS with the largest capacity and has the features of ultra-light weight and ultra-small volume of the semi-direct drive WTGS. The ultra-low cost per kilowatt hour of this intelligent WTGS brings the maximum benefits to customers.
The advanced medium-speed semi-direct drive ultra-compact transmission chain is adopted to result in short load transfer path; Double-circuit system design achieves higher electrical reliability; Fully optimized medium-speed permanent magnet synchronous generator lowers heat load, providing better stability; Highly integrated lubrication and cooling system ensures excellent thermal balance of the complete machine.
The overall structure of this WTGS is of ultra-compact design, which solves the problem that the onshore WTGS can’t be transported due to its large volume and hence makes the hoisting more convenient and enables the hoisting at places with more complex terrain.
This WTGS has large capacity and large impeller, which is designed on a customization basis; Owing to its high aerodynamic performance, it has better wind capture ability and high wind energy conversion efficiency, and also features wide range of speed regulation, high transmission efficiency and superior performance at low wind speed.
