Explain the working principle of a synchronous generator and its significance in power generation?

A synchronous generator works by generating an alternating emf and is also known as an alternator. It rotates at a synchronous speed, Ns, and is mainly used to generate large power at power stations.

What are the two important parts of a synchronous generator and their functions?

The two important parts of a synchronous generator are the stator, which carries the armature winding and the rotor, which produces the field. The induced emf is generated in the stator, while the main field required for generating the induced emf is produced at the rotor.

Why is a three-phase AC generator preferred over a single-phase power system?

A three-phase AC generator is preferred over a single-phase power system due to its numerous advantages, including better efficiency and power transmission.

Compare the construction of a synchronous generator with that of an induction motor.

<p>Similar to an induction motor, the two important parts of a synchronous generator are the stator and the rotor. However, in a synchronous generator, the output or the induced emf is generated in the stator, while the main field required to generate the induced emf is produced at the rotor.</p> Signup and view all the answers
