The Three Gorges of the Yangtze River, also known as the Xiajiang River or the Great Three Gorges, is located on the main stream of the Yangtze River in Chongqing, China and Hubei Province, starting from Baidicheng, fengjie county, Chongqing in the west and reaching Nanjinguan, Yichang, Hubei Province in the east, with a total length of193km, and consists of Qutang Gorge, Wuxia Gorge and Xiling Gorge.

The inflow of the Three Gorges Dam reaches 710.2 million cubic meters per second, which is the largest flood peak since the Three Gorges Reservoir was built. The Three Gorges Hydropower Station, also known as the Three Gorges Project, the Three Gorges Project and the Three Gorges Dam, is a large-scale water conservancy project in the upper reaches of the Yangtze River in China. The dam is located in Sandouping, Yiling District, Yichang City, in the Xiling Gorge of the Three Gorges, and forms a cascade dispatching power station with Gezhouba Hydropower Station not far downstream. ?

Extended data function:

The dam height of the hydropower station is185m, the water storage height is175m, and the reservoir is more than 600km long. It is the largest hydropower station in the world with 32 hydropower units with a single capacity of 700,000 kilowatts.

In July of 20 10, the unit of Three Gorges Power Station achieved the test target of 168 hours 18200MW full output. (The daily power generation can exceed 430 million kWh! About 5% of the country's daily power generation). From 65438 to 0949, the total power generation in China was only 4.3 billion kWh.

The preliminary planning of the Three Gorges Power Station is 26 units with 700,000 kilowatts, that is, the installed capacity is 65.438+08.2 million kilowatts, and the annual power generation is 84.7 billion kWh. Later, an underground power station was built at Baishijian Mountain, the right bank dam, and six 700,000-kilowatt hydro-generators were built. Together with the two 50,000-kilowatt power stations of the Three Gorges Power Station, the total installed capacity has reached 22.5 million kilowatts. In 20 12 years, the power generation of Three Gorges Hydropower Station is about 98 1 100 million kWh, which is five times that of Daya Bay Nuclear Power Station and 10 times that of Gezhouba Hydropower Station, accounting for about 3% of the national total annual power generation and 14% of the national hydropower generation. However, with the continuous development of hydropower in China, the hydropower share of the Three Gorges will continue to decline.
