Abstract: An ocean wave energy generation device was designed and constructed. Double float bowl structure and direct drive permanent magnet linear generation were used to change the structural model of ocean wave energy into that of electric energy. The linear generation current control method based on Park conversion theory was adopted to realize optimal control for the ocean wave energy generation device by controlling linear generation q shaft current. Analysis of ocean wave experiment results show that under natural state, the operating efficiency and stability of the ocean wave energy generation device were constrained by marine environment. The adopted linear generation current control method improves the efficiency and stability of ocean wave energy generation device.
Key words: ocean wave energy generation; linear generation; current control; Park conversion
