Description

technical field [0001] The invention relates to a device assembly for converting tidal wave energy into electric energy and a control method for optimal operation of the device assembly, belonging to the development and utilization technology of tidal wave energy. Background technique [0002] Tidal wave energy is mainly distributed in the sea near the coastline. Compared with wave energy in deep water areas far from the coastline, although tidal wave energy has a lower energy density, it is favored by many coastal countries for its advantages of low cost input, easy development and utilization, and low operation and maintenance costs. Converting tidal wave energy into electrical energy, providing electrical energy to nearby electrical equipment, and even conducting long-distance power transmission has become one of the main ways to develop and utilize tidal wave energy. [0003] At present, the existing tidal wave energy power generation device focuses on converting tidal ...

AI Technical Summary

Problems solved by technology

However, there are also some practical problems. For example, due to the large amount of sediment mixture near the coast, it will inevitably affect the normal operation of the transmission wheel; whether the seawater corrosion resistance of the transmission wheel, transmission rack and connector is good

Especially low, because the incoming wave direction of the tidal wave changes frequently with the ocean climate, which brings difficulties for the transmission mechanism to maximize the conversion of tidal wave energy into mechanical energy

Moreover, too many transmission wheels for energy transmission will inevitably generate losses in the process of energy transmission, which reduces the efficiency of development and utilization of tidal wave energy
