The wave power generation device has the characteristics that the application range is wide, the energy conversion efficiency is high, and the safety is good.

Description

technical field [0001] The invention relates to the technical field of wave power generation, in particular to a wave power generation device with high energy conversion efficiency and good safety and a control method. Background technique [0002] The development and utilization of marine energy is the direction of energy research. Under the situation that the earth's mineral energy is gradually depleted and the environmental situation is deteriorating, how to effectively use the abundant and renewable marine resources is very important; [0003] Wave energy is the cleanest renewable resource. The power of wave energy dissipated continuously along the coastline in the world reaches 27×105 MW, and the technically available wave energy potential is 10×105 MW. [0004] The existing wave power generation devices have the disadvantages of high price, low energy conversion efficiency and limited installation area. Contents of the invention [0005] The object of the present in...
