2. Xiangjiaba Hydropower Station - Yunnan Province.

3. Three Gorges Dam.

Hubei Province. 4. Gezhouba Water Conservancy Hub.

Hubei Province. 5. Ertan Hydropower Station - Sichuan Province. The Three Gorges Dam, located in Sandouping Town, Yichang City, Hubei Province, China, is 38 kilometers away from the downstream Gezhouba Water Conservancy Project, and is the largest hydropower project in the world today.

1. Lidaxi Luodu Hydropower Station - Sichuan Province.

Jinsha River Xiluodu Hydropower Station is located in the Jinsha River Gorge section bordering Leibo County, Sichuan Province and Yongshan County, Yunnan Province, with 9 sets of 770,000 kilowatts of giant hydro-generator units installed on the left and right banks of the power station, with a capacity of 13.86 million kilowatts, second only to the Three Gorges and Itaipu Hydropower Station in Brazil, ranking third among the world's power stations under construction and built.

Xiluodu Hydropower Station is a typical "three highs and three large" hydropower stations. The "three highs" are the high dam (300m level), the high intensity (basic intensity), and the high-speed water flow (close to 50m s); The "three big" are large flow (maximum discharge of about 50,000m s), large underground plant (top arch span of more than 30m), and large unit (single capacity of 770mw).

2. Xiangjiaba Hydropower Station - Yunnan Province.

Xiangjiaba Nalu Hydropower Station is located in the lower reaches of the Jinsha River at the junction of Shuifu City, Yunnan Province and Xuzhou District, Yibin City, Sichuan Province, only 1,500 meters away from Shuifu District, and is the last hydropower station of Jinsha River Hydropower Base, which was built by the Three Gorges Corporation.

It is 157 kilometers away from the dam site of Xiluodu Hydropower Station, and the barrage dam of the power station is a concrete gravity dam with a crest elevation of 384 meters, a maximum dam height of 162 meters, and a length of the dam crest.

3. Three Gorges Dam - Hubei Province.

The site of the Three Gorges Project Dam was selected in Sandouping, Yichang City, about 40 kilometers upstream of the completed Gezhouba Water Conservancy Hub. The Yangtze River water transport can directly reach the dam area.

After the start of the project, a quasi-first-class dedicated road with a length of about 28 kilometers from Yichang to the construction site and a cross-river bridge 4 kilometers downstream of the dam - Xiling Yangtze River Bridge were built. A number of wharves in the dam area have also been built. The dam area already has good traffic conditions.

4. Gezhouba Water Conservancy Hub - Hubei Province.

Gezhouba Water Conservancy Project is located at the end of the Three Gorges of the Yangtze River in Yichang City, Hubei Province, China, and is one kilometer downstream of Nanjin Pass, the outlet of the Three Gorges of the Yangtze River.

The reservoir area has a backwater of 110,180 km, which has improved the navigation conditions of the Sichuan River. The total capacity of the reservoir is 100 million cubic meters, due to shipping restrictions; In 2013, there was no flood regulation and peak shaving. After the completion of the Three Gorges Project, it can play a counter-regulating role in the uneven flow of the Three Gorges Project due to flood control and discharge, and has a counter-regulation reservoir capacity of 85 million cubic meters.

5. Ertan Hydropower Station - Sichuan Province.

Ertan Hydropower Station is located at the junction of Yanbian and Miyi counties in Panzhihua City, southwest border of Sichuan Province, China, in the lower reaches of the Yalong River, 33 kilometers away from the intersection of the Yalong River and Jinsha River, and 46 kilometers away from the urban area of Panzhihua.

There are three main hydropower stations in the Yellow River:

1.Yellow River Source Hydropower Station.

China's first hydropower station at the source of the Yellow River--- the Yellow River Source Hydropower Station was put into trial operation on the eve of the New Year, bringing light to the herdsmen of Maduo County, Guoluo Tibetan Autonomous Prefecture, and marking the end of the last county without electricity in Qinghai Province, with a dam height of 18 meters, an installed capacity of 2,500 kilowatts, and an average annual power generation of 17.53 million kilowatt hours, which broke ground on April 8, 1998, with a total investment of nearly 80 million yuan.

2.Longyangxia Hydropower Station.

Longyangxia Hydropower Station is 1,684 kilometers away from the birthplace of the Yellow River and 3,376 kilometers down to the mouth of the Yellow River. Located on the main stream of the Yellow River between Gonghe County and Guide County in Qinghai Province, Longyang Gorge is about 37 kilometers long and less than 100 meters wide. The Yellow River runs through the canyon from west to east, the cliffs on both sides of the bank are steep, the mountains are stacked, the river channel is narrow, the water flow is turbulent, the narrowest place is only about 30 meters, the relative height of the two banks is about 200 meters, 300 meters, and the highest can reach 800 meters.

3.Gongboxia Hydropower Station.

Gongboxia Hydropower Station is located on the main stream of the Yellow River at the junction of Xunhua Salar Autonomous County and Hualong Hui Autonomous County in Qinghai Province, 153km away from Xining City, and is the fourth large-scale cascade hydropower station in the section from Longyang Gorge to Qingtongxia in the upper reaches of the Yellow River. The project focuses on power generation, taking into account irrigation and water supply. The normal water storage level of the reservoir, the check flood level, the total storage capacity of 100 million cubic meters, the adjustment of the storage capacity of 100 million cubic meters, with daily regulation performance.

With an installed capacity of 1,500MW, a guaranteed output of 492MW and an annual power generation of 100 million kW·h, the power station is one of the important peak shaving backbone power stations in the Northwest Power Grid, which can improve the irrigation conditions of 160,000 mu of land downstream.

A hydropower station is a comprehensive engineering facility that can convert water energy into electrical energy. Generally, it includes reservoirs and hydropower station water diversion systems, power generation plants, mechanical and electrical equipment, etc., formed by water retaining and discharging buildings. The high-water level water from the reservoir flows into the plant through the water diversion system to drive the hydro-generator sets to generate electricity, and then feed it into the power grid through step-up transformers, switching stations and transmission lines.

Technical principle. The drop of water forms kinetic energy under the action of gravity, which diverts water from a high water source such as a river or reservoir to a low place, and uses the pressure or flow rate of water to impact the turbine to rotate, so as to convert the water energy into mechanical energy, and then the turbine drives the generator to rotate and cut the magnetic field lines to generate alternating current. The low-level water is distributed throughout the earth by absorbing sunlight and carrying out the water cycle, thus restoring the high-level water source.

Power station. Favorable factors.

1. Clean: Water energy is renewable energy and basically pollution-free.

2. Low operating cost and high efficiency;

3 On-demand power supply;

4 Inexhaustible, inexhaustible, renewable.

5 Control flooding.
