Oscillating water column control and monitoring
OCEANS 2016 MTS/IEEE Monterey, 2016This article covers research into cost reduction pathways for wave energy. The primary focus is the development and test of reliable and controllable power take-off (PTO) technology for oscillating water column converters (OWC). This is highly relevant to the ocean energy challenge.

The Hydrodynamic Efficiency of an Oscillating Water Column
24th International Conference on Offshore Mechanics and Arctic Engineering: Volume 2, 2005An oscillating water column device enables the conversion of wave energy into electrical energy via wave interaction with a semi-submerged chamber coupled with a turbine for power take off. This present work concentrates on the wave interaction with the semi-submerged chamber, whereby a shore based oscillating water column (OWC) is studied ...

Phase Control for the Oscillating Water Column
1986In this paper we investigate the use of optimal control techniques for improving the efficiency of the power-conversion system in an oscillating water column device. A mathematical model of the system is developed and an optimal control strategy for power-generation is determined.

Hydrodynamic characteristics of an oscillating water column device
Applied Ocean Research, 1995We consider a wave energy device consisting of a thin vertical surface-piercing barrier next to a vertical wall in finite depth water. Power is extracted due to a normally incident wave forcing the free surface of the fluid between the barrier and the wall to oscillate, in turn pumping the volume of air above the free surface through a uni-directional ...

Numerical Investigation of Bifurcation in Water Column Oscillator
10th International Conference on Nuclear Engineering, Volume 4, 2002Behavior of a water column oscillator with a cover gas system was studied experimentally and analytically. One of the free water surfaces was sealed with the cover gas, while the other was open to the atmosphere. The cover gas was supplied with a constant rate, and it was ejected through a valve when the water level reached a certain point.

Sensor control for an Oscillating Water Column plant
2013 World Congress on Sustainable Technologies (WCST), 2013The Oscillating Water Column concept consists of two key elements, a turbine located in a pneumatic energy collection chamber and a doubly fed induction generator that converts energy extracted by the turbine into a form that can be returned to the network.

A comparative analysis of Oscillating Water Column turbines
2018 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM), 2018Wave energy seems to be one of the most promising alternatives to the current energy issue. Pursuant to this fact, different devices have been developed so as to harness the energy that waves contain. Amongst all of them, Oscillating Water Column-based systems arise as the preferable technology in the scientific world.

Oscillations of a water column beneath trapped air
American Journal of Physics, 2011We investigate the natural oscillations of a water column beneath air trapped in a tube and demonstrate that the frequency of oscillation is lowest when the tube is about half full of water, and is higher when the tube is either mostly full or mostly empty. The familiar concepts of hydrostatics, ideal gases, and damped harmonic motion are indispensible
