Generator set power generation principle
The generation of electric energy by diesel generator sets and the generation of electric energy by hydropower, thermal power, wind power and other power generation equipment are all based on the same principle - the principle of electromagnetic induction.
When a part of a conductor in a closed circuit moves in a magnetic field and cuts the magnetic field lines, a current will be generated in the conductor. This phenomenon is called electromagnetic induction. The current produced is called induced current.
In a diesel generator set, the diesel engine generates a certain amount of power by burning mixed air. There are armature windings and field windings or permanent magnets inside the alternator. The armature windings are conductors, and the field windings or permanent magnets can generate magnetic fields. Therefore, the power of the diesel engine drives the generator armature winding or field winding or permanent magnet to rotate. Using the principle of 'electromagnetic induction', the generator will output an induced electromotive force, and a current can be generated through the closed load loop.
Therefore, in simple terms, the power generation principle of a diesel generator set is that the diesel engine transmits mechanical energy to the alternating current to generate electricity, causing the internal closed circuit of the generator to move relative to the magnetic field lines in the generator to generate electrical energy.
