Design diagram of wind power generation speed increaser

Can a 1 DOF planetary transmission increase wind turbine speeds?

The performance of a new, patent-pending solution of a 1 DOF planetary transmission is analyzed in this paper, meant to increase the speeds and torques in the counter-rotating wind turbines with counter-rotating electric generator.

What type of speed increaser does a wind turbine use?

The speed increasers for WTs can be of fixed-axes [ 3, 14, 15] or planetary type [ 12, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27 ], the latter being mainly used to produce high kinematic ratios, as is the case with counter-rotation wind systems [ 23, 24 ].

How does a 1 DOF speed increaser work?

The 1 DOF speed increasers have the properties of summing up the input torques generated by the wind rotors R 1 and R 2, as well as transmitting an independent external motion (in this case, the speed of the main wind rotor R 1) to the other three external links, in a determined way.

How does a speed increaser work?

Conventionally, the main input of the speed increaser is connected to the main wind rotor R 1, while the secondary input to the wind rotor R 2; the two outputs are connected to the rotor GR and stator GS of the counter-rotating electric generator.

How does a wind turbine work?

The common WT is a single-rotor system, with 1 degree of freedom (DOF) fixed axes or planetary transmission and a classical generator. The use of counter-rotating motions with either the wind rotors or the electric generator improves WT performance.

Are planetary speed increasers suitable for crwts with cregs?

The kinematic and static computing methodology, as well as the analytical models and diagrams developed for various case studies, might prove useful for researchers and designers in the field to establish the most advantageous solution of planetary speed increasers for the CRWTs with CREGs.
