4 FAQs about 5mw wind turbine transmission system design
Does NREL's 5MW reference wind turbine have a gearbox model?
NREL's 5MW reference wind turbine has been broadly employed by researchers around the world for structural design studies, but currently, there is no gearbox model in the wind turbine literature available for detailed investigations of the drivetrain. The systems engineering approach has been employed for designing this reference gearbox.
What is a wind turbine gearbox based on?
It is based on the four-point supports design: two main bearings and two torque arms. The gearbox component design is based on the related international design codes and the data from similar types of wind turbine gearboxes. A multibody system model of the gearbox is then developed.
What type of gearbox does a REpower 5MW turbine use?
The REpower 5MW turbine 5 has employed a similar high-speed gearbox with three stages. For the 5MW reference gearbox, the most common high-speed gearbox that has two planetary stages and one parallel stage is selected. Spur gears are easy to manufacture and perform best at low speeds and high torques.
What is a 5MW gearbox vulnerability map?
5MW gearbox vulnerability map. In this paper, a 5MW reference gearbox for an offshore wind turbine is presented. The aim of this work is to support conceptual studies and design comparisons of various offshore wind turbine models.
