Abstract-The potential of electric power generation from marine tidal currents is enormous. Tidal currents are being recognized as a resource to be exploited for the sustainable generation of electrical power. The high load factors resulting from the fluid properties and the predictable resource characteristics make marine currents particularly attractive for power generation and advantageous when compared to other renewable energies. Moreover, international treaties related to climate control have triggered resurgence in development of renewable ocean energy technology. Therefore, several demonstration projects in tidal power are scheduled to capture the tidal generated coastal currents. Regarding this emerging and promising area of research, this paper reviews marine tidal power fundamental concepts and main projects around the world. It also report issues regarding electrical generator topologies associated to tidal turbines. Moreover, attempts are made to highlight future issues so as to index some emerging technologies mainly according to relevant works that have been carried out on wind turbines and on ship propellers.Index Terms-Tidal current, marine technology, electric power generation, energy converter systems, state of the art.

“…After the rotor, another main component is blade, many attempts have been made on theoretical and experimental study of blade design [6][7][8][9][10] and there are outcomes that on increasing the number of blades, the solidity of the turbine increases and induced torque is higher. This reduces the start problem of the turbine.…”

“…However, conventional turbines are not technoeconomically viable for many micro hydropower sites. It is found that many attempts are being made to develop the turbine technology for zero head hydropower sites [6][7][8]. According to the literature review, it is found that techno-economic feasibility of zero head turbines is still a critical area to justify the feasibility of these turbines.…”

Abstract:In small-scale hydropower scheme, the most important component is electro-mechanical equipment. Since cost contribution of this component is high because hydrokinetic projects require negligible civil works. Turbine and alternator contribute a major fraction of the hydrokinetic projects. Thus, there is a requirement to estimates the electromechanical equipment cost for a hydrokinetic hydropower scheme. The present paper investigates design parameters of the hydrokinetic turbines and intends to develop cost correlation which depends on most critical parameters of hydropower sites such as velocity and power capacity. In this present work, three zero head turbines are considered including straight blade Darrieus, two Stage Savonius, and Gorlov Helical. The size and cost of major components have been calculated based on material, manufacturing, research and design, and assembly costs. Based on cost and site parameters, cost correlation has been developed. The obtained cost has been validated with available zero head turbines in the market and installed projects. A techno-economic analysis has been carried out to select economical hydrokinetic turbine for river and canal application.

“…However, there are some subtle differences amongst these two fields of application. Tidal turbines are typically larger in size (> 100 kW ), whereas river turbines are generally in the range of 1 kW to 10 kW [9,21,29,31]. Most marine turbines use horizontal axis rigid mooring/submerged generator configurations.…”

River Current Turbines are electromechanical energy converters that harness kinetic energy of a stream of flowing river water to generate electricity. Research in this domain is limited and various concepts are emerging only recently. In this paper, an extensive technology survey and comparison of various system options are discussed in order to formulate a basis for further analysis. Simplified mathematical modeling of an augmentation device and Darrieus type rotor has been carried out. Simulations are done in Matlab and results are given with graphical interpretations. In conclusion, directions for further investigation are given and the potential of this technology is re-stressed.
