Ocean current energy is mainly utilized for power generating. As an important new force of renewable energy source, it is being substantially developed worldwide. As the ocean current energy generator unit runs in seawater perpetually, design of sealing system for it is crucial. In this paper, the protective sealing system against seawater is designed for a 300kW ocean current energy generator unit in Zhoushan sea area. The sealing system includes mechanical sealing parts and detecting sensor parts. The mechanical sealing parts mainly prevent seawater leakage and the function of detecting sensor parts is mainly to send out alarming signal to the danger of leakage. The double protection of the two parts can guarantee the ocean current energy generator unit running safely in the sea water.

“…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.…”

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.

With the increased demand of clean energy and global warming measures, the renewable energy development has been increased recently. The TCP (Tidal Current Power) is one of the ocean renewable energy sources. Having the high tidal energy source in Korea, there are many potential TCP sites with strong current speed. The rotor, which initially converts the energy, is a very important component because it affects the efficiency of the entire system. The rotor performance is determined by various design parameters including number of blades, shape, sectional size, diameters and etc. However, the interactions between devices also contribute significantly to the energy production. The rotor performance considering the interaction needs to be investigated to predict the exact power in the farm. This paper introduces the optimum design of TCP turbine and the performance of devices considering the interference between rotors.
