On the definition of the power coefficient of tidal current turbines and efficiency of tidal current turbine farms

Renewable Energy, 2014
Abstract During the last decade, the development of tidal current industries has experienced a rapid growth. Many devices are being prototyped. For various purposes, investors, industries, government and academics are looking to identify the best device in terms of of cost of energy and performance.

Estimation of Mechanical Parameters and Tidal Current Velocity for a Tidal Turbine

IEEE EUROCON 2021 - 19th International Conference on Smart Technologies, 2021
This paper presents a novel methods for the estimation of the mechanical parameters and the tidal current velocity in a Tidal Energy Conversion System. The first method is based on a Luenberger Observer including the mechanical equation of the system, and the measurement of the electric current induced by the electrical machine. Then, the estimation of

Modeling tidal turbine farm with vertical axis tidal current turbines

2007 IEEE International Conference on Systems, Man and Cybernetics, 2007
A 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 ...

Modeling tidal turbines

OCEANS 2008, 2008
Performance prediction models are valuable tools for use in the development of tidal turbines. A model that can accurately predict the performance of a device can be used to optimize the design parameters more rapidly and at a much lower cost than carrying out the design studies using scale model tests. Tidal turbine models are principally dependent on

Optimal Operation of a Tidal Turbine [PDF]

open access: possible, 2022
The optimum operation strategy of a tidal turbine is calculated for a generic problem which consists of a small and shallow channel between two infinite reservoirs exposed to tidal waves. The optimal operating volume flow rate is found to be 1/√3 of the natural flow rate without employed tidal turbines and yields the maximum energy to be harvested per ...

Tidal turbine benchmarking exercise

Proceedings of the European Wave and Tidal Energy Conference, 2021
Uncertainty 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 ...
