Innovative drivetrain technology
We have developed and tested an innovative drivetrain for large-scale on and off-shore wind turbines comprising a medium-speed Brushless Doubly-Fed Induction Generator (Brushless DFIG) coupled to a one or two stage gearbox. The Brushless DFIG requires only a fractional size frequency converter, typically rated at one third of that of the generator. The key advantages of this drivetrain as compared to conventional ones are the low capital cost, low operations & maintenance costs, high reliability and greater compatibility with recent grid codes.
Several prototypes have been built and tested including 7 kW, 20 kW and 250 kW machines. We are currently developing a multi-megawatt system to be tested within a wind turbine in a test field in 2013. If you would like to receive more information about our technology, please contact us.
