The 100MW steam turbine-generator set for the Three Gorges
The turbine island for the Three Gorges Energy Xinjiang Hami Integrated Energy Demonstration Project utilizes a 100MW steam turbine model developed by Harbin Electric
The Three Gorges Dam is the world's largest capacity hydroelectric power station, with 34 generators: 32 main generators, each with a capacity of 700 MW, and two plant power generators, each with capacity of 50 MW, for a total of 22,500 MW.
Three Gorges uses Francis turbines with a diameter of 9.7/10.4 m (VGS design/Alstom's design) and a rotation speed of 75 revolutions per minute. This means that in order to generate power at 50 Hz, the generator rotors have 80 poles. Rated power is 778 MVA, with a maximum of 840 MVA and a power factor of 0.9.
The Three Gorges Project has regulated and supplemented water for the middle and lower reaches of the Yangtze River for 2,732 days, with a total water supplement of over 360 billion cubic meters, helping ensure drinking water supply and irrigation in these areas.
Since the filling of the reservoir in 2003, the Three Gorges Dam has supplied an extra 11 km 3 (2.6 cu mi) of fresh water to downstream cities and farms over the course of the dry season.
