Tidal power station in China

According to the national survey of tidal energy resources, there may be 19 1 tidal power stations in China, with an installed capacity of 2 1580 MW and an annual power generation of 61900 million kW·h, but less than 10 tidal power stations have been built, among which Jiangxia tidal power station in Zhejiang Province has the largest installed capacity. Six 500-700 kW units are designed and installed, with a total installed capacity of 3900 kW. One reservoir generates electricity in one direction, and the annual power generation is 1 1 10,000 kW h.

Jiangxia tidal test power station is the largest tidal power station in China, and it is also the test base for tidal power generation. The power station is located in Jiangxia Port in the southwest of Wenling City, Zhejiang Province, which is 16 km away from the urban area. The power station was approved by the State Planning Commission 1972, and the power station project was listed as "water conservancy and electric tidal power station project". The research focuses include the study of tidal energy characteristics, the development of tidal units, the technical problems of marine construction and its comprehensive utilization. Five bidirectional bulb tubular units have been installed in the power station. 1 unit was put into production on may 4th, 0980, and was completely built in February, 1985, with a total installed capacity of 3,200 kilowatts. Up to now, the scale remains the first in Asia and the third in the world, and the annual power generation is stable at more than 6 million kilowatts. By 2006, 65438+February 3 1, the cumulative power generation of the power station will be 65438+35 million kwh. At the beginning of 2006, No.6 power station was listed as a national "863" high-tech research and development project by the Ministry of Science and Technology, with an installed capacity of 700 kilowatts and a total investment of about100000 yuan. At present, the unit construction is progressing smoothly, and it is expected that Unit 6 will be installed and put into production in August this year.

After the completion of the power station, in addition to obtaining a lot of electricity, it also includes comprehensive utilization benefits such as reclamation, breeding and tourism. After the dam is built, the power station will become a reservoir with a water area of 1.37 square kilometers, which can be used for aquaculture. Because the reservoir area is less affected by natural disasters, the streams around the reservoir are full of fresh water, rich in nutrients, and the salinity of seawater is reduced, which is conducive to the growth of aquatic products. Cultured prawns, perch, yellow croaker and shellfish are harvested all year round. According to incomplete statistics, the annual output value of aquaculture in the reservoir area is150,000 yuan.

In the construction and production of Jiangxia tidal test power station, many scientific experiments have been completed. Practice has proved that it has the advantages of no immigration, no primary energy consumption, no flood threat, no impact on ecological balance and no pollution to the environment. The successful construction of Jiangxia tidal test power station has accumulated successful experience and made due contributions for China to build coastal industrial belts, expand development space, actively cultivate new growth points, build a conservation-oriented society and actively develop circular economy.
