A conventional wind turbine’s drivetrain typically consists of a rotor, a gearbox, a generator, and a power converter. In case of failure, the energy production is immediately stopped and expensive repair and maintenance work need to be done. This SFOE Project investigates a new modular drivetrain for wind turbines. An advanced gearbox allows for operating multiple generators at a higher rotational speed. Therefore, electric machines used in electric trucks can be now used in wind turbines as well. Depending on the wind speed, one or more generators are used to produce electric energy. Consequently, this modular drivetrain always operates generators in their most effective machine work point. Since this drivetrain can also be operated when some components fail, it enables a higher availability of the wind turbine. Moreover, small and light generators and power converters reduce service and maintenance costs. A simulation model was developed to engineer control algorithms of the modular drivetrain. Finally the simulation model was validated with a 1.75MW test system.
