摘　　要：提出一种低流速下总体发电量高的潮流能捕获系统,以实现深水网箱的能量自给。建立一个潮流半月周期内叶轮的总体发电量数学模型,对S型和H型2种不同叶轮的性能进行分析比较,得出S型叶轮在潮流流速较低时能自启动且总发电量较高;并对该叶轮结构参数进行优化,提高其在低流速时的功率系数。试验结果表明,该种潮流能发电装置能充分利用低流速潮流能为深水网箱供给能量,具有良好的使用效益。A tidal power generation system with high power output was presented to realize electric self-sufficiency for offshore cages. Therefore, a mathematical model of overall power output within semilunar period was established, and the characteristis of S-type rotor was compared with that of H-type rotor, the S-type rotor can generate more energy at low current. Optimizing the structure parameters of the rotor, the power coefficient has been improved. The test results showed that this kind of tidal power system can use fully tidal energy at low currency to supply power for offshore cages and has excellent economic benefit.
