Horizontal-axis tidal turbine blade loading for multi-frequency oscillatory motion [PDF]

open access: yes, 2012
This paper presents results from an experimental study which analysed the hydrodynamic response of the out-of-plane blade root bending moment for a horizontal-axis turbine exposed to multi-frequency oscillatory motion.

Design procedure and performance estimation of tidal current power system [PDF]

open access: yes
The demand to secure an alternative resource has been increased recently rather than fossil or nuclear\ud powers. One of the affordable ocean energy is the tidal energy since it is considered as a reliable and predictable power\ud source.

Ocean Energy: Using the Ocean's Tides, Waves, and Heat to Generate Electricity [PDF]

open access: yes, 2006
Key facts: - The oceans' tides, waves, current, and heat can be used to generate electricity. These resources are renewable, because the moon's gravity drives tides, and winds create waves.

Design, commissioning and performance of a device to vary the turbulence in a recirculating flume

open access: yes, 2013
Ambient turbulent flow structures are one of the key drivers that will determine the rate of wake recovery downstream of tidal turbines. For second and third generation arrays or farms such a parameter is critical for the determination of inter-device ...

Optimization on the Law of Variable-Pitch Vertical-Axis Tidal Current Turbine

open access: yesMATEC Web of Conferences, 2018
In order to improve the hydrodynamic performance of the vertical-axis variable-pitch current turbine, with analyzing on the existing design mentality of blade control mechanism, an optimized law of variable-pitch vertical-axis tidal current turbine was ...

DFIG versus PMSG for marine current turbine applications [PDF]

open access: yes, 2014
Emerging technologies for marine current turbine are mainly relevant to works that have been carried out on wind turbines and ship propellers. It is then obvious that many electric generator topologies could be used for marine current turbines. As in the

Experimental Study of Integrated Fan Turbine in Oscillating Water Column with Valve System in Venturi Directional and Solar Energy as Hybrid Energy Converter

open access: yesWave
Indonesia, with a maritime area of 7.081.000 km², has significant marine and energy potential. Its vast ocean can generate up to 1995 MW of energy, primarily from strong tidal movements, which can drive turbines to produce electricity.

One-Dimensional Modelling of Marine Current Turbine Runaway Behaviour

open access: yesEnergies, 2016
If a turbine loses its electrical load, it will rotate freely and increase speed, eventually achieving that rotational speed which produces zero net torque. This is known as a runaway situation.
