The principle of tidal power generation is similar to that of ordinary hydraulic power generation. By going out of the reservoir, the seawater is stored in the reservoir at high tide and stored in the form of potential energy, and then the seawater is released at low tide. The drop between high and low tide levels is used to drive the turbine to rotate and drive the generator to generate electricity. The difference is that the sea water is different from the river water. The accumulated sea water has a small drop, but the flow is large and intermittent. Therefore, the turbine structure of tidal power generation should be suitable for the characteristics of low head and large flow.
Due to the long and tortuous coastline of China, it is mainly concentrated in China's coastal areas, such as Zhejiang, Guangzhou, Fujian, Jiangsu and other regions. At present, China has begun to develop tidal energy since the 1950s, with increasingly mature technology, and has made great progress in reducing costs. However, there is still a certain gap compared with European and American countries. European and American countries have long coastlines, and their technology and development are relatively mature, The research on tidal power generation has been carried out in Europe and the United States since the beginning of the 20th century. Therefore, at present, tidal power generation in China still needs to break through technical barriers and reduce the gap with European and American countries.
As the future power supply is an important factor in China's economic development, especially the energy problem in the eastern coastal areas, tidal power generation will also have some development space in the future, but the disadvantages of tidal power generation, such as poor power generation economy, high power station cost, immature technology, will also restrict the development prospect of tidal power generation.
