Tips: Working Principle of AC Synchronous Generator.

Using the principle of electromagnetic induction to induce electric potential by cutting the magnetic field lines, the mechanical energy of the prime mover is converted into electrical energy output. The synchronous generator consists of two parts: a stator and a rotor. The stator is the armature that generates electricity, and the rotor is the magnetic pole. The stator is composed of an armature iron core, a three-phase winding uniformly discharged, a base and an end cover, etc. The rotor is usually a hidden pole type, consisting of an excitation winding, an iron core and a shaft, a guard ring, and a center ring. The excitation winding of the rotor is energized with a direct current, which produces a nearly sinusoidal distributed magnetic field (called the rotor magnetic field), and its effective excitation magnetic flux intersects with the stationary armature winding. When the rotor rotates, the magnetic field of the rotor rotates at the same time, with each revolution, the magnetic lines of force sequentially cut each phase winding of the stator, and a three-phase AC electric potential is induced in the three-phase stator winding. When the generator is running with a symmetrical load, the three-phase armature current synthesizes to produce a rotating magnetic field with a synchronous speed. The interaction between the stator magnetic field and the rotor magnetic field produces braking torque. From the steam turbine/water turbine/gas turbine, the input mechanical torque overcomes the braking torque to perform work.
