Problems solved by technology

Among them, the ocean energy generating device has been invented, and some research institutions have carried out research on it, but the proposed ocean energy generating device usually does not apply active control, due to the uneven and irregular force of ocean waves, the ocean energy It is not stably transmitted to the power generation load, which leads to low working efficiency of the generator and low energy conversion efficiency, so it cannot meet the requirements of stable energy transmission, which virtually reduces the scope of use of ocean energy

In addition, since the power generation load needs to output different electric energy according to different working conditions during actual work, if the ocean energy cannot be reasonably allocated, it is difficult to ensure that the generator works according to different external working conditions
