You don't know enough about hydroelectric power stations. Not only the Three Gorges Hydroelectric Power Station, but other hydroelectric power stations do not produce electricity when they discharge floodwaters. They divert water from the reservoir area to the turbine via the dam diversion tunnel. to drive the turbine generator to produce electricity. Flood drainage is a means of regulating water volume and storage capacity rather than a means of generating electricity. The flood gate is much higher than the water outlet of the turbine, and the water outlet of the turbine is usually at the bottom of the dam. . When you see a lot of water flowing under the dam. When there is a surge, it produces electricity.
The basic principle of hydroelectric generation in hydroelectric power stations is to use the difference in water level to produce electricity.icity with a hydroelectric generator, that is, the potential energy of the water is converted into mechanical energy. The energy from the water wheel and then the mechanical energy is used to drive the generator and obtain electricity. Scientists take advantage of the natural conditions of water level difference, effectively use fluid engineering and mechanical physics and carefully combine them to achieve the highest energy production, thereby providing cheap and free electricity. pollution to users.
Low-level water absorbs sunlight and circulates water throughout the earth, restoring the high-level water source. In 1882, the first recorded use of hydroelectric power took place in Wisconsin, United States. So far, the scale of hydroelectric power ranges from micro-scales, tens of watts used in rural areas of the third monde, to the millions of watts used to power large cities. ,

Operating principles of hydroelectric power plants:
< p >The working principle is to fully meet the requirements of safety, full power, economy and multiple supplies on the basis of economical and reasonable use of water resources and ensure the quality of water. 'energy. Hydroelectric power plants perform tasks such as frequency regulation, peak regulation, phase regulation and backup of the power system.Generally, during floods, the water volume should be fully utilized to put all units into operation to achieve full power generation and multiple supplies, and support the load of basis of the electrical system when operating during tank water; Duringthe supply period, the water load should be used as much as possible to support the base load and peak load of the power system, making full use of the adjustable output force to play the role of frequency regulation, peak regulation and emergency backup. system.
When a hydroelectric power station is in operation, it will be affected by the adjustment of compensation between different rivers; the impact of runoff adjustment when the same river is cascaded and the impact of power compensation between thermal power plants; and hydroelectric plants in the electricity system. The operation of a hydroelectric power station includes normal operation, special operation, abnormal operation and economic operation. For the hydroelectric power station to operate normally, attention must be paid to the maintenance of the power station.
