The Three Gorges Dam generator uses electromagnetic induction to produce electricity.
The Three Gorges Hydroelectric Power Station has installed 32 Francis turbine generator sets with a single capacity of 700,000 kilowatts (including 6 hydraulic generator sets in the underground plant), plus two 50 kW hydroelectric generator sets. 000 kilowatts in total installed. With a capacity of 22.5 million kilowatts and an annual electricity production of 100 billion kWh, it is the largest hydroelectric power station in the world.
We know that when wires intersect magnetic lines of force, they can generate an induced electromotive force. When wires are connected in a closed loop, current flows through them. convert mechanical energy into electrical energy. In the Three Gorges Dam generator, the iron core is connected to the turbine and rotates, called rotor. The coil is fixed and is called thestator. In a Francis turbine, water flows radially through the water guiding mechanism through the guiding effect of the volute, converting the kinetic energy of the liquid into static pressure energy, and then converts the energy of static pressure into kinetic energy of the rotor via the blades. The runner passes through the main shaft and generator. The rotor coupling causes the rotor to rotate and cut off the magnetic coil of the generator stator. It uses the principle of electromagnetic induction to generate high voltage electricity in the generator coil. is then amplified by the transformer and sent to the power grid via the transmission line. The water flow eventually flows out of the rotor wheel.
