Discussion on the distribution characteristics of large hydropower stations in China

Large hydropower stations in China are mainly distributed in southwest China, because most of the rivers in these areas are in the high Three Gorges area with large head.

Topographic features of large hydropower stations;

1, with large catchment area.

2, the river gap is large.

There are canyons here, which form a good dam site.

Large hydropower stations in China;

1 and China 1988 completed Gezhouba water control project in Hubei province, with an installed capacity of 2710.5 million kilowatts.

2. On 1986, China built an experimental Jiangxia tidal power station in Zhejiang Province, with an installed capacity of 3,200 kilowatts.

3. The first phase of China Guangzhou Pumped Storage Power Station has an installed capacity of 654.38+200,000 kilowatts, which is planned to be completed in the 1990s.

4. The Three Gorges Water Control Project started construction in 1994, which will be the largest hydropower station in the world with an installed capacity of17.86 million kilowatts.

Extended data:

According to the current classification and design standards of water conservancy and hydropower projects in China, hydropower stations can be divided into three main types according to the scale of power generation: large hydropower stations, medium hydropower stations and small hydropower stations.

Large hydropower stations with a total installed capacity of more than 250,000 kilowatts are called large hydropower stations; Among them, those with a power of more than 750,000 kilowatts are large type I, and those with a power of 25. 1 10,000 ~ 750,000 kilowatts are 20,000 kilowatts, which is called Zhong Da type II.

Power stations with a total installed capacity of 25,000 to 250,000 kilowatts are called medium-sized hydropower stations. Power stations with a total installed capacity of less than 25,000 kilowatts are called small power stations, among which power stations with a total installed capacity of 0.5 million kilowatts to 250,000 kilowatts are called small type I, and power stations with a total installed capacity of less than 0.5 million kilowatts are called small type II.
