Synchronous generator
Mar 13, 2018

Synchronous motor for generator operation. It is the most commonly used alternator. In the modern power industry, it is widely used in hydroelectric power generation, thermal power generation, nuclear power generation, and diesel power generation. Since the synchronous generator generally adopts DC excitation, when its stand-alone operation is independent, the voltage of the generator can be easily adjusted by adjusting the excitation current. If it is incorporated into the grid operation, the voltage cannot be changed because it is decided by the grid. At this time, the result of adjusting the excitation current is to adjust the power factor and reactive power of the motor.

The stator and rotor structure of the synchronous generator is the same as that of the synchronous motor. The three-phase form is generally adopted. In some small synchronous generators, the armature winding adopts a single phase.
