Which is the largest power station in China?

The Three Gorges Hydropower Station, namely the Yangtze Three Gorges Water Control Project, is also called the Three Gorges Project. The Xilingxia section of the Yangtze River in Yichang City, Hubei Province, China and the Gezhouba Hydropower Station in the lower reaches form a cascade hydropower station.

The Three Gorges Hydropower Station is the largest hydropower station in the world and the largest construction project in China. However, many problems caused by it, such as immigration, environment and so on, have been accompanied by great controversy since the moment it started construction. The Three Gorges Hydropower Station has more than ten functions such as shipping, power generation and planting.

The Three Gorges Hydropower Station was approved by the National People's Congress of China in 1992 and officially started construction in 1994. On the afternoon of June 1 2003, water storage and power generation began, and it was fully completed in 2009.

Construction scale:

The Three Gorges Dam is a concrete gravity dam with a length of 2,335 meters, a bottom width of 1 15 meters, a top width of 40 meters, an elevation of 185 meters and a normal water level of 175 meters. The dam body can resist the once-in-a-million-year flood, and the maximum flow can reach 65438+ million cubic meters per second.

The earthwork excavation and filling volume of the whole project is about 6.5438+34 million cubic meters, the concrete pouring volume is about 28 million cubic meters, and the steel consumption is 593,000 tons. The total length of the reservoir is more than 600 kilometers, the average width of the water surface is 1. 1 km, the total area is 1.084 km2, and the total storage capacity is 39.3 billion cubic meters, of which the flood control storage capacity is 2.21.50 billion cubic meters, and the regulation capacity is seasonal.

The Three Gorges Hydropower Station is arranged behind the dam, and 32 700,000 kW hydro-generator sets are installed, including 4 on the left bank 14, 2 on the right bank 12 and 6 underground. In addition, there are two 50,000-kilowatt power supply units with a total installed capacity of 22.5 million kilowatts, far exceeding the Itaipu Hydropower Station in Brazil, which ranks second in the world.

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 owned by the Three Gorges Power Station, the total installed capacity has reached 22.5 million kilowatts.

On June 5438+0, China Three Gorges Corporation announced that by 24: 00, 20 14, 3 1 day, the annual power generation of the Three Gorges Hydropower Station had reached 98.8 billion kWh, setting a new record for the annual power generation of a single hydropower station in the world, making it the highest hydropower station in the world for the first time.

The Three Gorges Power Station generates 98.8 billion kWh of electricity in the whole year, which is equivalent to reducing raw coal consumption by more than 49 million tons and reducing carbon dioxide emissions by nearly 1 100 million tons.
