The principle of modern energy production is essentially based on the use of conductors to cut magnetic lines of force. There are two ways that generator windings (conductors) cut magnetic lines of force: 1. The windings are fixed and the field magnetic. changes or turns. 2. The magnetic field is fixed and the winding rotates. Regardless of how the magnetic lines of force are cut, the rotating part is called the rotor and the fixed part, the stator. The generator of a hydroelectric power station uses the potential energy of water flowing from a high place to push a hydraulic turbine, and the hydraulic turbine drives the rotor of the generator to cut the magnetic lines of force to produce electricity. 'electricity. The generator of the thermal power plant uses the heat generated by the combustion of coal (oil, natural gas, waste, etc.) to transform water into steam toto drive the steam engine. The steam engine drives the generator rotor to cut the magnetic lines of force. produce electricity. Similarly, the principles of nuclear power generation and wind power generation are basically the same, except that they use different energy sources to drive the generator rotor to cut the magnetic lines of force .
1. Principle of diesel generator: driven by diesel engine The generator works and converts the energy of diesel into electricity.
In the cylinder of the diesel engine, the clean air filtered by the air filter is fully mixed with the high pressure atomized diesel fuel injected by the injector. Under the upward pressure of the piston, the volume decreases and the volume decreases. the temperature rises quickly. High, reaching the ignition point of diesel. Diesel ignites, gas mixture burns violently, expandsrapidly in volume and pushes the piston downward, which is called "work".
2. Gasoline Generator: The gasoline engine runs the generator, converting gasoline energy into electrical energy.
In the cylinder of the gasoline engine, the mixed gas burns violently, expands rapidly in volume, and pushes the piston down to do work. Whether it is a diesel generator or a gasoline generator, each cylinder performs work in a certain order. The thrust acting on the piston becomes the force that causes the crankshaft to rotate through the connecting rod, thereby causing the crankshaft to rotate.

1. Functional Characteristics of DC Generator
< p>DC generators are easy to use and reliable, and can directly supply electrical power to various electrical equipment requiring DC power. VSHowever, there is a collector inside the DC generator, which is prone to sparking and has low power generation efficiency. DC generators can generally be used as DC power sources required for DC motors, electrolysis, electroplating, alternator charging and excitation, etc.2. Functional Characteristics of Alternator
Alternator refers to a generator that generates alternating current under the action of external mechanical force. This type of generator can be divided into synchronous alternator and asynchronous alternators. .
Synchronous generators are the most common among alternators. This type of generator is excited by direct current and can provide both active and reactive power. It can be used to power various loads requiring alternative power. is powered. Additionally, synchronous generators can be divideddivided into four types depending on the different engines used: steam turbine generators, hydraulic generators, diesel generators and wind turbines.
