How many kilowatt hours of electricity can my country's most famous tidal power plant produce?

In 1961, France built a tidal power station at the mouth of the Rance, on the Channel coast, near the town of San Mano. It is one of the first tidal power stations built in the world and was once the largest tidal power station in the world. The tidal range here is 10.9 meters. The maximum length can reach 13.5 meters; the reservoir dam is 350 meters long, and the water surface of the reservoir can extend up to 20 kilometers long at high tide. There are 24 reversible turbines with a diameter of 5.35 meters installed in the power plant dam, each with a power of 10,000 kilowatts, a power output of 240,000 kilowatts, and an annual power supply of 53 billion of watts/hour. France also built a giant tidal power plant in San Mano Bay. This power plant has an installed capacity of 10 million kilowatts. This is equivalent to plus 40 times that of Lens Power Station; the annual electricity production reaches 25,000 billion watts per hour, almost 50 times that of Lens Power Station. France is also preparing to build three tidal dams across the 2,000 square kilometers of San Mano Bay and assemble the largest hydraulic turbine unit to generate an annual electricity output of 35 trillion watts per hour. Since the 1980s, China has successively built a number of small and medium-sized tidal power stations in various coastal areas and put them into operation to generate electricity. The largest tidal power station is the Jiangxia Test Tidal Power Station in Wenling County, Zhejiang Province, which was built in May 1980. It is also one of the largest two-way tidal power stations built in the world. It is located in Jiangxia Port, at the northern end of the bouch of Yueqing, in southern Zhejiang. Jiangxia Port is a closed seaport. A 15.5 meter clay core rockfill dam was constructed at the port to form a port reservoir with a total storage capacity of 4.9 million cubic meters and an effective power generation storage capacity of 2.7 million cubic meters. The maximum tidal range here is 8.39 meters and the average tidal range is 5.08 meters; the power of the plant is 3,200 kilowatts in 1989, the electricity production capacity was 620 million watts per hour; The characteristic of the two-way tidal power station is that it can generate electricity in the direction of high tide and low tide. Jiangxia power station can produce electricity for 14-15 hours every day and night, which is 30-40% more electricity generation than the one-way tidal power station.e. The Jiangxia Power Station can supply 10 billion watts/hour of electrical energy to the Wenling and Huangyan power grids every year.

Another large-scale tidal power station in China is the Xingfuyang Tidal Power Station in Pingtan, Fujian, with an average tidal range of 4.54 meters and a maximum of 7.16 meters. The station's annual power generation capacity can reach 3.15 billion watts per hour.

The main method of using tidal energy is tidal power generation. Two physical conditions must be met to use tidal power generation: first, the tidal amplitude must be large, at least a few meters. civil construction projects. The working principle of tidal power generation is similar to that of general hydropower generation, that is, a dam is built at the river mouth.hure of a river or bay to form a natural reservoir and the hydroelectric generator is installed in the dam. Tidal power stations can be single or double reservoirs.

42 places. According to the official website of the Beijing government, as of August 15, 2023, there were 42 hydropower plants in Beijing with a total installed capacity of 22,469 kilowatts, distributed in 6 districts including Fangshan, Mentougou, Yanqing, Huairou, Miyun and Pinggu. , including 30 diversion hydropower plants, 5 dam-type hydropower plants, 7 hybrid hydropower plants, which use reservoirs to generate electricity. There are 17 rural hydropower plants and 9 relevant reservoirs and dams, with total storage capacity of 281.15 million cubic meters.
