First of all, I forgive you for not understanding the principles of hydroelectric power generation.
To produce electricity, you need potential energy and kinetic energy. By the way, the kinetic energy you mentioned is one of the energies. The water level is low and the flow is high. If we want to produce the same output, the speed of the unit will be very low and the size will be large. When we want to fully utilize the water resources of the river, the selected value. This model will exceed our human capabilities. For example, ultra-low speed and ultra-large size (theoretically exists). Our materials, structure and project cost can all exceed the standard. Either the extraordinary model cannot be produced or it cannot be exploited. Consequently, the development of a river basin is a matter of rational use of water resources. Make reasonable use ofthe potential and kinetic energy of water and choose a reasonable model. And to satisfy us as humans. And this cannot exceed our capabilities.
At present, the highest water height can reach more than 1,000 meters, and the lowest can reach 1 to 3 meters. Different models are available. Every shape is also subject to structural constraints, and you don't have to be as big as you want. As small as you want. For example, for impact units, we only have 6 nozzles at most. For bulbs, the minimum water height is only around 2 meters, which is subject to certain technical restrictions.
1. A hydraulic generator consists of a hydraulic turbine and a generator. The hydraulic turbine is driven by water, just like a roadside water wheel. The generator is driven by a water turbine, via a shaft.
2. The partThe rotating part of the generator is called the rotor and the circle around the rotor is the stator. There are copper wires inside the stator that transmit energy outside. The rotor also has copper wires. However, the rotor's copper wires are not used to provide power to the outside world. Instead, the outside world provides direct current. The rotor. Once energized, the rotor becomes an electromagnet. The electromagnet The iron rotates to produce electricity. ! !
