Hybrid Drivetrain Design – Working Principle and Application

Sanja Vasin Bojić

Emerging engineering challenges in wind power electricity generation bond with stringent industrial requirements, have tendency to outline development and design process in the ready set go manner. From given predisposition one of the consequences may be highlighting of certain research area or even worse - deflection from the basic functional requirements in wind turbine drive train design. The paper presents a proposal of novel drive train technology – gear transmission unit with continual variation of transmission ratio which can provide direct synchronization to public electric grid, efficient energy conversion and wider operating range of wind turbine rotor. Beside mechanical, electronic and software system design, novel wind turbine configuration is also presented.

Key words: design, drivetrain, continual variation, wind turbine, hybrid system.
