一种浮式潮流能水轮机载荷试验模拟方法

A Method of Test Simulation for the Load of Floating Tidal Current Turbine

考虑潮流能水轮机模型试验中相似准则难以满足的问题,基于模型水轮机载荷的低频率、相对小量级的特点,提出一种新的方法等效模拟海洋潮流能水轮机载荷特性。该方法基于水流喷射,利用水流反作用力模拟水轮机载荷。搭建了潮流能载体水轮机载荷模拟试验平台,开发了相应的测试技术,进一步论证了载荷模拟结果在时域和频域上与水轮机载荷的对比一致性,期望为相关研究人员提供技术支持。

Considering that the similarity criterion cannot be met in the model test, as the load on the turbine is of low frequency and relatively small order, a new method is put forward to simulate the load on the turbine,which is based on aqua jet and simulation of the load using water reactive force. The authors have built a test platform for simulating the load on the turbine of a tidal power station and developed the measuring technique.The consistency of the load simulation results is compared in the time domain and frequency domain. We hope that the results of the paper can provide technical support for the related researchers
