Design of a hydraulic power take-off test rig for wave energy converters
2016 Techno-Ocean (Techno-Ocean), 2016a hydraulic test bench for a wave energy converter was designed and built. Reciprocating motion generated by incident wave was rectified by a hydraulic circuit, and the rectified flow drives a generator. In this experiment, total efficiency was 40% to 50% using 48-pole generator. Also a Simulink program was made to simulate the hydraulic circuit. Power

Design tradeoffs of an oil-hydraulic power take-off for wave energy converters
Renewable Energy, 2018Abstract This paper presents the main design tradeoffs that should be handled when developing oil-hydraulic Power Take-Off devices aiming at the maximization of energy extraction from waves with a point absorber wave energy converter. These tradeoffs were identified in a case study of a new Power Take-Off concept.

Numerical Analysis on Hydraulic Power Take-Off for Wave Energy Converter and Power Smoothing Methods
Volume 10: Ocean Renewable Energy, 2018One of the primary challenges for wave energy converter (WEC) systems is the fluctuating nature of wave resources, which require the WEC components to be designed to handle loads (i.e., torques, forces, and powers) that are many times greater than the average load.

OCEANS 2015 - Genova, 2015
Wave energy is a promising new player in the renewable energy field. The exploitable power within the world's oceans is significant and many developers try to capture it by developing wave energy converter (WEC) concepts. This research focussed on the conversion of the WEC motions into usable electricity by the power take-off system (PTO). Specifically,

Effect of front-back wave asymmetry on a hydraulic power take off system
This study highlights the role of wave geometry, more specifically wave front-back asymmetry, for the technical design and operation principles for an oscillating water column (OWC) type wave energy converter WEC. For a selection of 12 sea-states and 8 wave models we simulate the relation between average front-back wave asymmetry and average generated ...Shokoufa Zeinali +4 more

Bond graph modelling of a wave energy conversion system with hydraulic power take-off
Renewable Energy, 2012A system viewpoint is essential in the study of wave energy converters, since several different energy domains are involved in such devices. In this regard, bond graph, a graphical, port-based approach to modelling engineering systems, serves as a useful tool.

Design of a hydraulic power take-off system for the wave energy device with an inverse pendulum
China Ocean Engineering, 2014This paper describes a dual-stroke acting hydraulic power take-off (PTO) system employed in the wave energy converter (WEC) with an inverse pendulum. The hydraulic PTO converts slow irregular reciprocating wave motions to relatively smooth, fast rotation of an electrical generator.
