The basic principle of hydroelectric power generation in a hydroelectric power station is to use the difference in water level to produce electricity with a hydroelectric generator. In other words, the potential energy of water is converted into mechanical energy of hydraulics. wheel, then the mechanical energy is used to drive the generator to 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 power generation capacity, so that people can use an electricity cheap and pollution-free.
Low-level water absorbs sunlight and circulates water throughout the earth, restoring the high-level water source. In 1882, the first recorded application of hydroelectric power took place in theWisconsin, United States. So far, the scale of hydroelectric power ranges from micro-scales, tens of watts used in rural areas of the third world, to millions of watts used to power large cities. ,

Operating principles of hydropower plants:
The operating principle is to fully meet the requirements of safety, comprehensive power generation, economy and multiple supply on the basis of economical and rational use of water resources and ensuring the quality of electrical energy. Hydroelectric power plants perform tasks such as frequency regulation, peak regulation, phase regulation and backup of the power system.
In general, during floods, the volume of water must be fully utilized to put all unities in service to achieve full power generation and multiple supplies, and support the base load of the power system when operating during reservoir water; During the 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 the normal operationmale, special exploitation, abnormal exploitation and economic exploitation. For the hydroelectric power station to operate normally, attention must be paid to the maintenance of the power station.

1 . Electricity production using natural gas. Natural gas is sent through a pipeline to a turbine where the gas is mixed with air and ignited for combustion at constant pressure. The hot gas drives the turbine, which is connected to a generator by a shaft. The generator then produces an electric current. , which is conducted through a conductive system to a transformer.
2. Oil energy production. The turbine is driven by hot steam. The hot steam is heated by the combustion of the fuel oil. The fuel oil is transported from the fuel oil tank to the boiler and burned in the boiler. The shawlur released is absorbed by the water circulating in the pipe. superheated steam under pressure is transported to the steam turbine through the pipe and flows through the blades. The blades turn a shaft, and the turbine shaft is connected to a generator that produces electric current. The principles of coal-fired power generation are fundamentally similar.
3. Hydroelectricity. Use the water level difference and cooperate with the hydroelectric generator to generate electricity. because of the waterDue to the potential difference, the water flow can pass through the giant turbine blades at a very fast speed, and the blades will rotate at high speed (using the potential energy of the water to convert it into mechanical energy of water). wheel, then using mechanical energy to drive the generator.) This drives the drive shaft inside the turbine. Finally, mechanical energyique is converted into electrical energy.
