This programme is for the research and development of Power Take Off (PTO) technology, a fundamental component of a wave energy converter.  The key task of the PTO is to transform the motion from the prime mover, as it reacts with itself or a fixed reaction point, and convert it into a smooth electrical output ready for delivery to the grid.

Projects in this programme started at three different stages in 2015.

 

A feasibility study to determine if a novel electric generator with an integral magnetic gearing system, developed for a lightweight wind turbine generator, can be adapted for use as a PTO system by integrating with a high-efficiency power electronics and intelligent control system.

This project developed a PTO module comprising a gearbox and generator capable of converting the reciprocal motion of a wave energy converter into grid-compliant electricity at a low cost of energy.

The Blue Power PTO, based on ballscrew technology, has the opportunity of achieving early and reliable deployment in conjunction with a range of WEC designs by utilising existing hardware components and subsystems in this novel application.

The WaveDrive project progressed the design and development of a low cost, highly reliable and highly controllable linear generator (LG) power take off (PTO) technology for wave energy converters (WECs).
