Research on Hydrodynamic Characteristics of Wave Energy Power Plant

Ocean energy is a kind of high-quality renewable energy. Therefore, it will not be exhausted and has attracted wide attention. China’s coastline is 18,000 kilometers long, so China has abundant ocean energy. In order to realize the utilization of wave energy, the research on wave energy power generation technology has never stopped. Wave energy generation refers to the use of wave motion to generate electricity, first converting wave energy into intermediate energy through a conversion device, and then converting intermediate energy into electrical energy. Combining with China’s actual situation, China’s research on wave energy devices mainly has three types: oscillating water column, pendulum, sink and float. Due to the huge difference in sea conditions and the characteristics of China’s offshore waves with short periods and relatively low energy density, wave energy conversion devices must be independently developed, and hydrodynamic behavior research is the basic work. In this paper, through the theoretical analysis and numerical calculation research methods, the hydrodynamic behavior characteristics of the wave energy conversion device are studied, and the simulation analysis is performed using the hydrodynamic software AQWA.
