The hydroelectric generator is divided into two parts, the turbine and the generator.
A hydraulic turbine is made up of valves, volutes, water guide vanes, channels, suction pipes and other components
A generator is usually consisting of a main shaft, bearings and a stator; , a rotor and other components.
Water flows through the valve, volute, water guide vane, channel and suction tube, causing the channel to rotate.
The runner drives the generator rotor to rotate in the stator through the main shaft and bearings, making the rotor a rotating magnetic field. The stator coil moves to cut the magnetic lines of force, thereby generating induced electricity. potential, generate current to produce electricity and convert the potential energy of the converted water into electrical energy.
Today's electricity is generatedalso produced by power plants. The most common power plants include hydroelectric power, wind power, thermal power, solar power, etc.
How electricity is produced
The matter around us is made up of atoms. The atom itself also has a structure consisting of a nucleus and electrons located outside the nucleus. Among them, the number of negatively charged electrons is equal to the number of positively charged protons in the nucleus. When two objects rub against each other, part of the electrons will be transferred, which constitutes the phenomenon of electrification by friction. The electricity thus obtained is also called static electricity. When we put on or take off sweaters, we may feel "electricity", which is caused by the recombination and discharge of static electricity.
There are many free electrons in the metal wire. When the coil of the metal wire moves in the magnetic field, electrons are moved by the magnetic field, and voltage and current are generated in the wire. the principle of the generator discovered by Faraday. It should be noted that no matter how complex the electrical phenomenon, the total number of charges is always conserved, that is, equal amounts of positive and negative charges are always produced and annihilated at the same time.
The process of generating electricityTo produce electricity, magnets and coils that generate electricity are needed. Magnets have a magnetic force that attracts metals such as iron. The range reached by this force is called the magnetic field. By moving the coil through this magnetic field, the coil generates electricity. However, in a strong magnetic field, if the coil cannot be moved (without causing a change in force mmagnetic), electricity cannot be produced.
Thermal power generation uses thermal energy generated by burning coal, oil, liquefied natural gas and other fuels to heat water in the water pipes of the steam boiler at high temperature and high pressure, which drives the steam. turbine to rotate, thereby causing the generator to produce electricity.
Hydropower uses dams to convert the potential energy of water flowing from high to low places into kinetic energy. At this time, the hydraulic turbine installed in the lower part of the waterway is driven by the water flow. rotate, and the water turbine and the generator are connected to drive the generator to rotate and convert the mechanical energy into electrical energy.
Nuclear power generation, for example, uses nuclear energy to heat water in areactor to produce steam. Driven by steam, the steam turbine rotates the generator to produce electrical energy.
Solar thermal power generation uses a heat collection device to collect solar thermal energy and heat water in the water pipe to generate steam, which in turn drives the turbine generator to produce electricity.
The above is how electricity is generated which I have sorted out. Thanks for reading.
