A deep-sea platform energy self-supply device and a control method therefor are disclosed. The device includes a working platform of a deep-sea platform, buoys mounted at a bottom of the working platform, wave energy piezoelectric assemblies disposed at the bottom of the working platform, and ocean current energy piezoelectric assemblies disposed at bottoms of the buoys. The present disclosure directly converts kinetic energy of fluid in the ocean into electric energy by using a wave energy piezoelectric plate and an ocean current energy piezoelectric plate, thereby supplying power to the deep-sea platform and achieving energy self-supply for the deep-sea platform. The device also dissipates kinetic energy of the fluid, such that the amplitude of waves decreases as the kinetic energy of the fluid decreases, thereby achieving a wave-dissipating effect, enhancing operational stability of the working platform, and extending the service life of the working platform.
