摘　　要：随着潮流能开发利用技术日趋成熟,对其测试工作也提出了更高的要求。然而,在潮流能装置性能测试中,波流相互作用的影响往往被忽略,导致测试结果不准确。为了研究波流相互作用对测试的影响方式与程度,采用物理模型试验的方法,对垂直轴潮流能发电装置模型进行了试验研究。通过分析波流作用下装置的扭矩、转速及发电功率,发现波流与发电装置耦合作用明显,相比不存在波浪影响的情况下,叶轮的转动、主轴的扭矩都变得不规则,启动流速变小,同时,扭矩、转速及发电功率的瞬时值显著增大。测试结果表明,波流相互作用对装置性能测试影响显著,平均影响程度约10%,研究结果为今后潮流能发电装置性能测试标准的制定和完善提供了参考和依据。With the development and utilization of tidal current energy technology becoming increasingly mature,higher requirements have been put forward for its testing work.However,the influence of wave-current interaction is often neglected in the performance test of tidal energy convertors(TECs),leading to inaccurate test results.In order to study the way and extent of influence of wave-current interaction,a physical model experiment is carried out on the vertical-axis TEC.Through a series of static water towing tests and wave-making towing tests,the effects of waves on the power generation performance of TECs at different flow rates are studied.Through the analysis of the torque,rotational speed and output power of device under the wave-current interaction,it is found that the wave-current and device coupling effect each other significantly,compared with no wave effect,and the rotation of the impeller and shaft torque is irregular,startup velocity decreases.At the same time,torque,rotational speed and output power of instantaneous value increase significantly.The test results show that the wave-current interaction has a significant impact on the performance test of the device,with an average impact of about 10%.The research results provide a reference and basis for the formulation and improvement of the performance test standards for TECs in the future.
