Description

technical field [0001] The invention relates to power generation technology, in particular to a wave energy power generation system and a control method. Background technique [0002] Wave power generation is the conversion of wave energy into electrical energy. At present, the wave power generation system mainly includes mechanical transmission, hydraulic transmission or pneumatic mode. Among them, the wave energy power generation technology based on hydraulic transmission uses a mechanism similar to a hydraulic pump to accept waves. It first converts wave energy into hydraulic energy for storage, and then drives the generator through the hydraulic motor to convert the stored hydraulic energy into electrical energy. Hydraulic transmission has the characteristics of large force and low speed, which matches the characteristics of waves. In the energy conversion chain of wave energy-hydraulic energy-electrical energy, hydraulic energy plays the role of temporary storage and sm...
