Main Exciter The exciter (sometimes called the main exciter) is a synchronous generator that has its stator and rotor windings…

Following phasor is phsor diagram of a two-axis salient pole generator. The following points apply to the drawing of phasor…

The stator, also called the armature, carries the three-phase AC winding. The rotor, also called the field, carries the DC…

Again assume that the generator is loaded and operating in a steady state. In this situation the magnitude of the…

Assume the generator is loaded and operating in a steady state. If the peak-to-peak or rms value of the stator…

The rotating field in the air gap of a synchronous machine is generally considered to be free of space harmonics,…

The stator, also called the armature, carries the three-phase AC winding. The rotor, also called the field, carries the DC…

The theoretical operation of synchronous generators and synchronous motors is almost the same. The main differences are the direction of…

In all power systems the requirement is that the steady state speed deviation, and hence frequency, is kept small for…

Gas turbines are usually started by a DC motor or an air motor. Either system is available for most turbines…
