基于波浪能的浮式装备随体供电技术研究

Research on Built-in Power Supply Technology of Floating Equipment Based on Wave Energy

摘要:

随着我国海洋开发向深远海方向发展，各类海洋装备长时间工作于深远海域，能源供给极不方便，迫切需要一种便捷的能源供给方式。针对上述需求，提出了一种可内置于海洋浮式装备的波浪能转换装置，以海洋浮式装备为载体，依靠载体在波浪作用下的垂荡运动获取波浪能，由于惯性波浪能转换装置的振子在弹簧的作用下产生振动，驱动动力输出(PTO)系统做功，将波浪能转换为电能。基于流体力学基本原理， 建立了浮体与波浪能装置的耦合运动学模型和能量转换数学模型，分析不同参数对 RAO 和 CWR 的影响。通过优化分析，本文所提出的基于惯性原理的双共振波浪能转换装置能量转换效率最高可达 45%以上，可有效地应用于海洋浮式装备，具有可观的应用前景。

Abstract:

With marine development of China extending to deep-sea and open sea，all kinds of marine equipment are operated in deep sea and open sea for a long time，which causes the extremely inconvenience of energy supply，and hence there is an urgent need for a convenient method of energy supply. In response to the above requirement，this paper proposes a wave energy converter that can be built into marine floating equipment. The converter system uses marine floating equipment as a carrier，and relies on the heave motion of the carrier under the action of waves to obtain wave energy. The vibrator of the inertial wave energy converter generates vibration under the action of the spring，and drives the power output(PTO)system to work and convert the wave energy into electric energy. Based on the principle of fluid mechanics，a coupled kinematics model of floating body and wave energy converter and a mathematical model of energy conversion are established，and the influences of different parameters on RAO and CWR are analyzed. Through optimization analysis，the energy conversion efficiency of the double resonance wave energy converter based on inertia principle is up to 45%，which prove that the system can be effectively applied to marine floating equipment and has considerable application prospects.
