The working principle of Three Gorges Dam power generation is: water energy is converted into kinetic energy, and kinetic energy is converted into electrical energy. The water level difference (i.e. water height) and flow flow into the volute through the 12.4 meter diameter pressure steel pipe at the water inlet. The huge impact of the water flow causes the turbine to spin at a speed of 75 revolutions per minute. minute. The generator on the same main shaft as the turbine also rotates at a speed of 75 rpm. Rotating at the same speed can generate powerful electricity. Simple principle: Convert the potential energy of water into electrical energy. The dam stores water to raise the water level, plus the high potential energy of the water impacts the turbine to turn the turbine and drive it. the generator is working.
The turbine is like thewindmill that we played with when we were kids, except it is more efficient than the windmill.
