As early as 1912, the world s first tidal power station was built. What method of explanation was us

The so-called tidal power: refers to the sea level is rising and falling, tidal power generation is the use of the back and forth surge of the waves to drive the turbine to drive the rotor to rotate, so as to output the process of electrical energy, this energy is inexhaustible.

An example is used.

The world's first tidal power station was built in 1960. On November 26, 1960, the world's first tidal power station was inaugurated in Gulf Saint-Malo, Brittney, France.

Tidal power is a form of hydroelectric power that uses the movement of tidal currents, or the rise and fall of tidal seas, to obtain energy from them. Although not yet widely used, tidal power has great potential for the future of electricity**. In addition, it is easier than wind and solar**, and in Europe the tides have been used to drive mills for thousands of years, mainly for grinding grains.

It was one of the world's first tidal power stations and was once the largest tidal power station in the world. The tidal range here is in meters. up to meters; The dam is 350 meters long, and the water surface of the reservoir can extend to 20 kilometers at high tide.

There are 24 reversible turbines with a diameter of 10,000 kilowatts each with a power of 240,000 kilowatts and an annual power supply of 53 billion watt-hours in the dam of the power station. France has also built a giant tidal power station in the Bay of Saint-Mano. The plant has an installed capacity of 10 million kilowatts.

It is equivalent to more than 40 times that of the Lens power station; The annual power generation reaches 25 trillion watt-hours, almost 50 times that of the Lens power station.

The world's first tidal power station was built in 1913 on the shores of the North Sea in Germany. The largest tidal power station is the Lens tidal power station in Saint-Maro Bay, France, with an installed capacity of 240,000 kilowatts.

In 1912, Germany built the world's first experimental small tidal power station: the Busum tidal power station.

In 1912, Germany built the world's first experimental small tidal power station: the Busum tidal power station.

It was built on November 26, 1960 in the Bay of Saint-Malo, Brittney, France.

Tidal power station is a general term for devices, equipment, and facilities that use tides to generate electricity, converting ocean tidal energy into electricity. Tidal power plants are the only marine energy plants with practical applications.

The world's first experimental small tidal power station was built in Germany in 1912 and was the Busum Tidal Power Station;

The tidal power station at the mouth of the Lens River in France, which was put into operation in 1968, installed 24 hydro-generator units of 10,000 kilowatts, with an annual power generation capacity of about 500 million kilowatt hours, which was the largest tidal power station in the world as of the 80s, and its power generation cost was comparable to the cost of general thermal power. China's Jiangxia tidal power station in Zhejiang, China, has an installed capacity of 3,200 kilowatts, ranking third in the world.

Answers:d This question mainly tests the candidates' popular science knowledge.

Famous teacher explained in detail] The principle of tidal power generation is similar to that of ordinary hydroelectric power, through the reservoir, the seawater is stored in the reservoir at high tide, stored in the form of potential energy, and then the seawater is released at low tide, and the difference between high and low tide levels is used to drive the turbine to rotate and drive the generator to generate electricity. Therefore, the line is withered and d.

China's coastal tidal resources are abundant, and the development of tidal power stations began in 1958. By 1979, Shandong Rushan Tidal Power Station had been built, with an installed capacity of 300 kilowatts; Shandong Jingang Tidal Power Station, with an installed capacity of 165 kilowatts; Zhejiang Xiaoshashan Tidal Power Station, with an original installed capacity of 40 kilowatts, was later transformed to 200 kilowatts; Zhejiang Xiangshan Tidal Power Station with an installed capacity of 100 kilowatts.

Tidal power stations, despite their various forms, are generally composed of three parts: the first part is the dam, which is used to hold back seawater to form a reservoir, and is the main part of the power station. The length and height of the dam should be determined according to the local geographical conditions and the size of the tidal range.

Because the tidal range is not very large, the height of the dam is generally lower than that of the barrage of the river hydroelectric power station; The second part is the water diversion system, which is composed of various gates and aqueducts, and its main role is to cause the drop between the water surface of the reservoir and the sea surface, as well as the high and low reservoirs, so as to promote the hydro-generator unit to generate electricity; The third part is the power generation equipment and transmission lines with hydro-generator units as the main body. The power generation equipment is installed in the underwater part of the dam body and is the heart of the power station. With these three parts, the tidal power station is ready to work.

According to the survey of tidal energy resources in China, 191 tidal power stations may be developed across the country, with an installed capacity of 21,580 MW and an annual power generation capacity of 61.9 billion kW·h. However, less than 10 tidal power stations have been built, among which the Jiangxia tidal power station in Zhejiang Province has the largest installed capacity, with 6 units of 500 700kw designed and installed, with a first-class unit of 3900 kw, and a single reservoir for one-way power generation, with an annual power generation of 11 million kw·h.

Jiangxia Tidal Experimental Power Station is the largest tidal energy power station in China and a test base for tidal power generation. The power station is located in Jiangxia Port, southwest of Wenling City, Zhejiang Province, 16 kilometers away from the city. The construction of the power station was approved by the State Planning Commission in 1972, and the power station project was listed as a "water conservancy and electric power tidal power station project", and the research focus includes the study of tidal energy characteristics, the development of tidal units, the technical problems of offshore buildings, and comprehensive utilization.

The power station installed 5 two-way bulb through-flow units, and the No. 1 unit was put into operation on May 4, 1980, and all the construction was completed in December 1985, with a capacity of 3,200 kilowatts. The scale still remains the largest in Asia.

First, the third in the world, the annual power generation is stable at more than 6 million kilowatt hours, and by December 31, 2006, the power station has generated a total of 100 million kilowatt hours. At the beginning of 2006, the No. 6 power station was listed by the Ministry of Science and Technology as a national "863" high-tech research and development project, with an installed capacity of 700 kilowatts and a total investment of about 10 million yuan. At present, the construction of the unit is progressing smoothly, and it is expected that the No. 6 unit will be installed and put into operation in August this year.

After the completion of the power station, in addition to obtaining a large amount of electricity, it also includes comprehensive utilization benefits such as reclamation, aquaculture and tourism. After the dam of the power station is built, it becomes a reservoir, and the water area of the reservoir is square kilometers, which can be used for aquatic product breeding. Because the reservoir area is affected by natural disasters is small, the streams around the reservoir have fresh water into the reservoir, which is rich in nutrients, and the salinity of the seawater is reduced, which is conducive to the growth of aquatic products, and the shrimp, sea bass, yellow croaker, shellfish, perennial harvest, according to incomplete statistics, the annual output value of aquaculture in the reservoir area is 15 million yuan.

In the construction and production of Jiangxia Tidal Experimental Power Station, many scientific experimental topics 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 environmental pollution. The successful construction of Jiangxia Tidal Experimental Power Station has accumulated successful experience and made due contributions to the construction of China's coastal industrial belt, expanding development space, actively cultivating new growth points, building a conservation-oriented society, and actively developing circular economy.
