Design and Research of Hydraulic Power Generation System with Superposed for Multi-point Array Type Wave Energy Convertor

针对现有波浪能发电模式所存在的不足之处,提出一种可用于多浮子波浪能发电装置的液压发电系统.在波能捕获部分数学模型的基础上,采用Matlab/Simulink与AMESim联合仿真的方式,对系统进行动态仿真分析.结果表明,应用该系统,各浮子可实现双向行程做功,不同浮子双向运动机械能转换为液压能后可实现能量叠加,蓄能器稳压效果明显,液压马达在三种不同工况下输出转速及转矩均保持稳定,验证了该系统用于多浮子波浪能发电装置的可行性.

This paper proposes a hydraulic power generation system with multi-floater wave energy converter aiming at the shortage of the current wave energy power generation mode. Based on the mathematical modelling for capturing wave energy, dynamic simulation analysis of this system is car- ried out by the co-simulation of Matlab/Simulink and AMESim. The results show that each floater can achieve two-way power stroke with the application of the system, resulting in the energy superpo- sition by the conversion from mechanical energy to hydraulic energy due to the two-way motion of dif- ferent floaters. It also shows that the accumulator has great voltage stabilizing effect. Then, the hy- draulic motor can keep stable output rotation rate and torque for three different operation conditions, which verifies the feasibility of the application of this system on the multi-floater wave energy converter.
