在安装商业潮流水轮机之前，该装置的1：30比例模型在循环水槽中进行了试验。事实证明，这是涡轮机非传统控制策略的第一次物理演示，该策略通过允许转子进入超速来限制设备上的推力。试验表明，这种简单易实现的操作概念是一种在能量流中管理转子推力负荷的经济有效和可靠的手段。随后的试验强调了正确计算控制器增益参数的重要性，否则可能会损害涡轮的性能特性。当将这些结果与商业设备的结果联系起来时，与环境和模型试验的规模都有许多重要的差异。尽管如此，结果被认为是令人鼓舞的，并为全面部署提供了信心。版权所有©2016由ASME
Ahead of the installation of a commercial tidal stream turbine, a 1:30 scale model of the device was tested in a recirculating flume tank. This proved to be the first physical demonstration of the turbine’s unconventional control strategy, which limits the thrust forces on the device by allowing the rotor to enter an overspeed. The tests showed that this simple to implement concept of operation is a cost-effective and reliable means of managing the rotor thrust loads in energetic flows. Subsequent tests highlighted the importance of correctly calculating the controller gain parameter, otherwise detrimental turbine performance characteristics can be expected. When relating these results to that of the commercial device, there are a number of important differences associated with both the environment and scale of the model tests. Despite this, the results are considered encouraging, and provided confidence for the full-scale deployment.Copyright © 2016 by ASME
