动态电缆对海上浮式风机发电效率的影响

为解决传统线型电缆不利于漂浮式风电场电缆运行维护的问题，提出动态电缆概念，分析不同结构形式对电缆产生的影响。开展半潜式浮式基础在风浪流联合载荷作用下的全耦合时域仿真模拟。分析悬链线形传统电缆与缓波形动态电缆对浮式风机水动力性能的影响，发现缓波形动态电缆对漂浮式风机水动力性能的影响较小，有利于浮式风机发电。对比采用不同电缆的浮式风机发电效率，结果显示，采用2种线型电缆的风机发电效率降低幅度均随着风浪夹角的增大而降低，且采用缓波形电缆发电效率的降低幅度小于采用悬链线形电缆。

Influence of Dynamic Cables on Power Generation Efficiency of Offshore Floating Wind Turbines

In order to solve the problem that the traditional linear cable is not conducive to the operation and maintenance of floating wind farm cables, the concept of dynamic cable is proposed, and the influence of different structural forms on the cable is analyzed. The fully coupled time-domain simulation of the semi-submersible floating foundation under the combined action of wind, wave and current loads is carried out. The influence of traditional catenary and slow waveform dynamic cables on the hydrodynamic performance of the floating wind turbine is analyzed. It is found that the influence of the slow waveform cable on the hydrodynamic performance is small, which is beneficial to the power generation of floating wind turbine. The power generation efficiencies of the floating wind turbines using different cables are compared, and the results show that the reduction of the power generation efficiency of the wind turbine using both cables decreases with the increase of the angle between the wind and waves and the reduction of the power generation efficiency using the slow waveform cable is smaller than that using catenary cable.
