摘　　要：波浪能是一种清洁、可再生的新型能源,波浪能发电装置在海上作业时会受到变化的风、浪、流载荷作用,需要系泊系统保证其稳性和安全性。以适用于中国南海500 m水深的振荡双浮体式波浪能发电装置为研究对象,运用频域计算与时域计算结合的方法对双浮体及其系泊系统的运动响应和动力载荷进行计算,获取极端海况与工作海况下浮体运动和系泊缆索张力的时历数据。参照BV船级社NR-493规定的海上浮式结构物系泊安全系数规范,对3种系泊方案进行安全校核和对比分析。选定其中一种系泊方案,通过改变系泊系统以及能量转换器(PTO)的参数,探究参数变化对双体波浪能装置运动响应以及系泊系统特性的影响,为类似应用于深水的双体波浪能装置系泊系统的设计提供参考。Wave energy is a new type of clean and renewable energy.Wave energy power generation devices will be subject to varying wind,wave and current loads when operating at sea,so mooring systems are required to ensure their stability and safety.Taking the oscillating dual-body floating wave energy power generation device suitable for 500 m deep in the South China Sea as the research object,the combination of frequency domain calculation and time domain calculation is used to calculate the motion response and dynamic load of the double floating body and its mooring system,and obtain the time history data of the floating body motion and mooring line tension under the extreme and working sea conditions.The safety check and comparative analysis of the three mooring schemes are carried out according to the mooring safety factor specification for offshore floating structures specified in BV Classification Society NR-493.One of the mooring schemes is selected,the influence of parameter changes on the motion response of the dual-body wave energy device and the characteristics of the mooring system are explored by changing the parameters of the mooring system and the power take off(PTO),and finally provide reference for the design of similar dual-body wave energy deep-sea device mooring systems.
