Does anyone know the efficiency of the Three Gorges Dam generators? THANKS

Its efficiency is not a fixed value, but changes depending on different unit parameters, that is, it changes depending on the operation of the tank. This includes hydraulic head loss and various other kinetic and electrical energy losses.

But for hydraulic turbines, there is this reference.

In the early 1990s, the performance of the runner developed by two factories and one institute (Dongfang Electric Co., Ltd., Harbin Electric Machinery Co., Ltd. and Water Conservancy and Hydropower Research Institute) was close to the international level and the efficiency of the model reached more than 93%. Among them, the Water Resources Institute has two yields reaching 93.8% and 93.41% (the international highest level at that time was 93.48%-94.31%); the wheel rotates and drives the generator rotor to rotate through the main shaft. When direct current passes through the generator rotor coil, the bobine of the rotor generates a rotating magnetic field. During the rotation process, the magnetic field lines are cut by the stator coil. According to the principle of electromagnetic induction, a voltage will be generated. the stator coil, and once the stator coil is connected to the load, a current will be generated in the stator coil. The water level difference (i.e. water height) and flow flow into the volute through the steel pipe under pressure at the water inlet. The huge impact of the water flow causes the turbine to spin at a speed of 75 revolutions per minute. the same main shaft as the turbine also rotates at the same speed to produce powerful electricity.

The Three Gorges Hydropower Station is the Three Gorges Water Conservancy Project on the Yangtze River, also known as the Three Gorges Project. The Xiling Gorge section of the Yangtze River in Yichang City, Hu Provincebei, China, and the Gezhouba Hydropower Station downstream form a cascading power plant. The Three Gorges Hydroelectric Power Station is currently the largest hydroelectric power station and clean energy base in the world.

How does the Three Gorges Dam produce electricity?

The principle of electricity production from the Three Gorges Dam Three Gorges:Water flows against the turbine wheel, causing it to spin and drives the generator rotor through the main shaft. When direct current passes through the generator rotor coil, the rotor coil generates a rotating magnetic field during rotation. The field lines are cut by the stator coil. According to the principle of electromagnetic induction, the stator coil A voltage will be generated. After the stator coil is connected to the load, a current will be generated in the stator coil. The difference of neitherwater calf (i.e. water height) and flow flow into the volute through the steel pipe under pressure to the water inlet. The huge impact of the water flow causes the turbine to spin at a speed of 75 revolutions per minute. the same main shaft as the turbine also rotates at the same speed to produce powerful electricity.

Three Gorges Dam Tourist Area

Three Gorges Dam Tourist Area is located in Yichang City, Hubei Province. It was officially opened to the outside world in. 1997 and was designated by the National Tourism Administration in 2007. It was classified as a 5A national tourist attraction by the Bureau. The tourist area is based on the Three Gorges Project, the world's largest water conservation project, and comprehensively presents the engineering culture and water conservation culture, providing tourists multi-functional servicesnnels integrating tourism, science and education, leisure and entertainment, integrating modern engineering, natural landscapes and The organic combination of humanities and landscapes makes it a popular destination for friends at home and abroad foreign.tourist destination.

There is an exhibition hall in the Dam Closure Memorial Park in the Three Gorges Dam Scenic Area. You can learn more about the Three Gorges Project through the graphic materials in the exhibition hall. In the park, you can also see a rockery landscape made of three-dimensional triangular interception stones, as well as large-scale construction equipment and other physical exhibits. Because it is located downstream of the dam, it has become a place for taking scenic photos with the Three Gorges Dam. Tourists like to take photos here with the dam in the background.
