Why does water at high altitudes have gravitational potential energy and can drive generators to pro

(1) The dam is built to increase the water level upstream. The mass of the water remains unchanged, the height increases, and the gravitational potential energy increases when the water falls, the gravitational potential energy is converted into kinetic energy; , and the kinetic energy increases, thus causing the generator to generate electricity.

(2) The generator works based on the principle of electromagnetic induction. It consumes mechanical energy and obtains electrical energy. It is a device that converts mechanical energy into electrical energy.

So the answer is: movement; electromagnetic induction.

What is the principle of a hydroelectric generator (water turbine)?

Hydraulic generator refers to a generator that uses a hydraulic turbine as the main engine to convert water energy into electrical energy. When water flows through the turbine, the energy de water is converted into mechanical energy. The rotating shaft of the turbine drives the generator rotor, which converts mechanical energy into electrical energy and produces it.

A hydrogenerator is driven by a water wheel. Its rotor is short and thick, the unit starts and connects to the network in a short time and the operating program is flexible. In addition to general electricity generation, it is particularly suitable as a peak shaving unit and as an emergency backup unit. . The maximum capacity of the hydrogenerator unit reached 800,000 kilowatts.

I hope to adopt him!

The principle of a hydroelectric generator (water turbine) is that when water circulates through the turbine, the energy of the water is converted into mechanical energy. The rotating shaft of the turbine drives the generator rotor, which converts mechanical energy into electrical energy and produces it.

The first hydroelectric power station in the worldwas built in France in 1878. The first hydroelectric power station in the Americas 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 world's leading large-capacity hydroelectric generators are the 718,000 kVA stator water-cooled semi-umbrella hydroelectric generator at the Grand Coulee Hydroelectric Power Plant, ther 737,000 kVA stator water-cooled semi-umbrella hydroelectric power station of Itaipu Hydroelectric Power Station and the 700,000 kVA water-cooled stator hydroelectric generator. -Guli Hydropower Station cooled semi-umbrella hydroelectric generator, kVA air-cooled umbrella hydrogenerator and 800,000kW Xiangjiaba hydrogenerator, etc.
