WaveCat是一种新型的超前波浪能转换器，经过测试，目的是确定其在不同海况下的性能，为设备优化、数值模型验证和控制系统概念验证奠定基础。测试是在普利茅斯大学 COAST 实验室的洋盆中以 1:30 的比例进行的。采用了最先进的控制系统，并沿着波场记录了超越率和设备运动。据观察，发电量取决于波高和周期，对于相同的波高，周期越小往往会产生更大的溢顶率，从而产生更大的发电量。由于实验室时间限制，仅测试了吃水/干舷的一种配置；采用这种配置，在有效波高为 0.083 m 或更高（对应于原型值中的 2.5 m 或更高）时发生溢顶。这些实验结果构成了WaveCat未来开发和优化的基础。
WaveCat, a novel overtopping Wave Energy Converter, was tested with the aim of determining its performance under different sea states, establishing a starting point for optimisation of the device, numerical model validation and proof-of-concept for the control systems. The tests were carried out at a 1:30 scale in the Ocean Basin of the COAST Laboratory at University of Plymouth. A state-of-the-art control system was implemented, and overtopping rates and device motions were recorded alongside the wave field. It was observed that power generation is dependent on both the wave height and period, with smaller periods tending to produce greater overtopping rates, and therefore greater power generation, for the same wave height. Due to time constraints in the laboratory, only one configuration of draft/freeboard was tested; with this configuration, overtopping occurred under significant wave heights of 0.083 m or more, corresponding to 2.5 m or more in prototype values. These experimental results form the basis for future development and optimisation of WaveCat.
