Modeling tidal turbine farm with vertical axis tidal current turbines
2007 IEEE International Conference on Systems, Man and Cybernetics, 2007A tidal current turbine is a device for harnessing energy from marine currents, and functions in a manner similar to a wind turbine. A group of tidal current turbines distributed in a site in ocean is called a tidal turbine farm. Among all tidal current energy extraction schemes, turbine farm is regarded as among the most promising turbine ...

Micropower From Tidal Turbines
Volume 1B, Symposia: Fluid Machinery; Fluid Power; Fluid-Structure Interaction and Flow-Induced Noise in Industrial Applications; Flow Applications in Aerospace; Flow Manipulation and Active Control: Theory, Experiments and Implementation; Fundamental Issues and Perspectives in Fluid Mechanics, 2013In addition to utility-scale power generation (e.g., rated capacities greater than 106 W), there are also possibilities for tidal current generation at the micro-scale (e.g., rated capacities less than 102 W) that could provide power to autonomous oceanographic instrumentation. This paper presents performance characteristics of a high-solidity, helical,

Tidal turbine benchmarking exercise
Proceedings of the European Wave and Tidal Energy Conference, 2021Uncertainty in tidal turbine loading contributes significantly to conservatism in turbine design. This uncertainty originates not only from a lack of knowledge of the flow field at a particular site, but also from lack of understanding of the fundamental physics which govern the loading and performance of tidal turbines in unsteady and turbulent flow ...

Generator Topologies for Horizontal Axis Tidal Turbine
2020Over the last decade, research on technologies to exploit tidal currents kinetic energy for renewable electricity generation has had a significant growth. However, as to date, there is not a consensus worldwide on standard Power Take-Off (PTO) systems, due to the current immaturity of tidal energy converters technologies.

Hydraulic Performance of the Tidal Turbine
2011 Asia-Pacific Power and Energy Engineering Conference, 2011This paper does researches for vertical axis tidal turbine based on academic analysis and numerical simulation. Keep on the tip speed ratio and change the inlet speed. And then analyze hydraulic performance of the different tidal turbines. For the problem in the tidal technology, use airfoil cross-section that is suitable for low speed flow use, change

Tidal Current Turbine, Wind Turbine and Their Dynamic Modelling
2014Wind and tidal current are of the most common energy resources for generating electricity in the near future because of the oil problems (crises and pollution). Within that frame, wind and tidal current energies are surging to the fore. The dynamic model of the offshore wind and tidal current is very important topic for dealing with these renewable ...
