Everyone can do it. Hydroelectric power uses water with potential energy from high places such as rivers and lakes to flow to low places, converts the potential energy in it into the kinetic energy of the hydraulic turbine , then uses the hydraulic turbine as such. the driving force to drive generators to produce electrical energy. Use hydraulic power (with water head) to push hydraulic machinery (water turbine) to rotate, converting water energy into mechanical energy. If another machine (generator) is connected to the water turbine, electricity can be generated when the water turbine spins. At this moment, the mechanical energy is converted again into electrical energy. In a sense, hydropower is the process of converting the potential energy of water into mechanical energy and then into electrical energy. The Three G hydroelectric power stationbarleys and Gezhouba hydroelectric power station are fresh water.
There is also tidal power generation. , which uses the rising tide of sea water. Falling tide tidal power generation involves constructing a dam in a tidal bay or estuary to form a reservoir, and placing an installed hydroelectric generator in or at side of the dam to use the rise and height. drop in sea water level as the tide rises and falls to allow sea water to pass through the turbine Promote hydroelectric generator to produce electricity. From an energy point of view, it uses the potential energy and kinetic energy of seawater to convert it into electrical energy using a hydroelectric generator.
The principle of a hydroelectric generator (water turbine) is that when water circulates in the turbine, the energy of the water is converted into mechanical energyfuck. The rotating shaft of the turbine drives the generator rotor, which converts mechanical energy into electrical energy and produces it.
The world's first hydroelectric station was built in France in 1878. America's first hydroelectric station was built in Wisconsin, United States, in 1882, using a direct current generator. After 1889, three-phase alternators began to be used. Since then, the capacity of a single machine has increased rapidly. In 1890, it was only 15,000 kW. By 1955, it could produce 105,000 kW generators. Before 1949, the capacity of a single unit of Chinese-made hydraulic generators did not exceed 200 kW. After 1949, the automobile industry developed vigorously. In 1958, it was able to produce a single unit of 72,500 kW. In 1972, a double unit of 300,000 kW. -An internal water cooling water generator has been produced. The main hydro generatorslargest capacity electric generators in the world are the 718,000 kVA stator water-cooled semi-umbrella hydroelectric generator of the Grand Coulee Hydroelectric Station, the 737,000 kVA stator water-cooled semi-umbrella hydroelectric generator of the Itaipu Hydroelectric Power Plant and the 700,000 kVA water stator hydroelectric generator. -Guli Hydropower Station cooled semi-umbrella hydroelectric generator, kVA air-cooled umbrella hydrogenerator and 800,000kW Xiangjiaba hydrogenerator, etc.
