Abstract

Tidal energy is the kinetic energy created when the gravitational forces of the Moon and the Sun cause periodic reciprocal horizontal movements of seawater, mainly concentrated on shores, waterways between islands, or in the mouths of bays. Tidal currents can usually be classified as reciprocating or rotating, and are mainly the more steady flow in submarine waterways and straits as well as the regular flow of seawater due to tides. Compared to waves, tidal currents are much smoother and more regular. Tides can change in size and direction on average twice a day in response to the rise and fall of the tide. China has extremely rich marine resources, among which tidal energy is abundant, especially offshore tidal energy which is among the highest in the world in terms of power density, therefore the development and production of tidal power generators to improve efficiency and performance is an important step in the implementation of China's sustainable development strategy. Most of the existing tidal power devices are fixed directly to the seabed, which is more conducive to stable energy harvesting, but if the device needs to be installed farther offshore and in deeper water, a floating structure is required to facilitate installation and save costs. A new floating bi-directional tidal power generation device is proposed based on existing research examples and research project requirements, which converts tidal energy into electricity through three stages: energy capture, transmission, and generation.
