Problems solved by technology

The oscillating water column type is driven by an air turbine, and its conversion efficiency is very low when the waves are small. At the same time, its shore-type application usually involves problems such as high engineering cost; the pendulum type technology is suitable for the characteristics of large thrust and low frequency of waves, and the frequency response It has a wide range and high energy conversion efficiency, but the maintenance of its mechanical and hydraulic systems is relatively difficult. In order to adapt to the harsh marine environment such as typhoons, it focuses on ensuring high overall structural reliability and power generation stability. The area is small, and the ability to capture wave energy is weak, resulting in a high cost per unit power; the canard technology has high energy conversion efficiency, but the ability to resist waves is weak, the reliability is poor, and it is easy to be damaged; the point absorption type The wave energy capture efficiency and energy conversion efficiency of the technology are high, and the device construction is relatively simple, but it also has the disadvantage of weak wave resistance; the wave-surpassing technology has high energy conversion efficiency and high overall stability. Water turbine technology has become more common in the hydropower industry, and the survivability of the device is relatively high, but its engineering cost is relatively high
