The speed increasers are typical components of a large diversity of renewable energy systems (RES), like wind turbines or hydropower plants, used to harmonize the low input speed of
These installations have numerous turbines connected to a central power-generating unit, which requires a speed increaser to stabilize the electrical output frequency and the generator speed,
Provided are a step-up gear for a wind turbine generator and a wind turbine generator that further improve the life of a planetary bearing.
According to the present invention, the rotational speed transmitted from the blade is increased through the source gear, the connecting gear, and the center gear, so that the generator can...
A two-stage speed-increaser for a wind turbine: planetary first stage followed by a parallel wheel–pinion second stage. The work described the design and verified gears and bearings per ISO,
Aiming to extend the use of WTs with counter-rotating wind rotors (CRWRs) and CREGs to medium- and large-scale applications, this paper introduces and analyzes a higher-performance
The proposed system yields various technical benefits: it has a compact design, increases the output power (which makes it suitable for medium- and large-scale wind turbines) and allows a
Twenty-two variants of speed increasers are further generated and analyzed, four of which are innovative solutions proposed by the authors.
concerned with, and partially recommends, the design of conversion systems. Therefore, the aim of this paper is to propose a specific algorithm for the conceptual synthesis of speed increasers integrated
The results are useful to wind turbine designers and developers in the process of functional and constructive optimization of wind system solutions with a counterrotating electric generator.
