A numerical study on a floating hemisphere wave energy converter with hydraulic PTO system
OCEANS 2016 - Shanghai, 2016The aim of this study is to conduct a hydrodynamic analysis of a point absorber-type floating hemisphere with Power take-off(PTO) system for an optimum design of wave energy converter(WEC). In general, to predict the behavior of WEC, the equation of floating body motion can be solved in the frequency-domain analysis.

Numerical study on multi-buoy-type wave energy converter platform with hydraulic PTO system
OCEANS 2017 - Aberdeen, 2017This study examined the hydrodynamic performance of a multi-point absorber with a hydraulic power take-off (PTO) system and estimated the optimal conditions for maximum power extraction. The multi-point absorber is composed of two hemispheric buoys with a hydraulic PTO system.

Oscillating bodies constitute an important class of wave energy converters, especially for offshore deployment. Phase control by latching has been proposed in the 1970s to enhance the wave energy absorption by oscillating bodies (especially the so-called point absorbers).

Pitching paddles, hydraulic PTOs and shallow water waves: the development of a coupled non-linear modelling approach for WEC design [PDF]
, 2020 Investor confidence in the wave energy industry has been eroded by the collapse of forerunners who went “too big too quickly” and relied on models that were developed primarily for other industries such as Oil & Gas. The underlying assumptions of linear wave theory may be valid for the analysis of large static structures but it proves inaccurate when ...

Strategies for active tuning of Wave Energy Converter hydraulic power take-off mechanisms [PDF]
Renewable Energy, 2016 This paper presents a study of practically implementable active tuning methodsfor a Wave Energy Converter (WEC) power take-off (PTO). It is distinguished from other simulation studies by the level of detail and realism in the inputs and the PTO model ...

ASME/BATH 2021 Symposium on Fluid Power and Motion Control, 2021
Abstract Wave energy is a promising renewable energy resource for coastal regions around the world, but is not yet an economically competitive source of electricity. More effective power take-off (PTO) designs would help to make wave power a feasible and clean source of energy. To do this, PTOs need to: i) enable controlled actuation, ii)

DEVELOPMENT OF A COMPUTER-CONTROLLED, HYDRAULIC, POWER TAKE-OFF (PTO) SYSTEM
Transactions of the ASAE, 2005Nearly all tractor PTO arrangements used today consist of a rotating mechanical shaft with two or more universal joints. This arrangement continues to be an entanglement hazard. By driving the attachment with fluid power, this hazard could be eliminated.
