Synchronous Condensor

Synchronous Condensor is also known as Synchronous Compensator or Synchronous Phase Modifier. A synchronous condenser or a synchronous compensator is a synchronous motor running without a mechanical load. It can generate or absorb reactive volt-ampere (VAr) by varying the excitation of its field winding. It can be made to take a leading current with over-excitation …

MMF Method of Voltage Regulation

MMF Method is also known as Ampere Turn Method. The synchronous impedance method is based on the concept of replacing the effect of armature reaction with an imaginary reactance, the Magnetomotive force (MMF). The MMF method replaces the effect of armature leakage reactance with an equivalent additional armature reaction MMF so that this MMF may …

Armature Winding

Armature Winding is the winding, in which voltage is induced. Field Winding is the winding in which the main field flux is produced when the current through the winding is passed. Some of the basic terms related to the Armature Winding are defined as follows: Turn: A turn consists of two conductors connected to one …

Synchronous Generators

Definition: The synchronous generator or alternator is an electrical machine that converts the mechanical power from a prime mover into an AC electrical power at a particular voltage and frequency. The synchronous motor always runs at a constant speed called synchronous speed. Working Principle of Synchronous Generator The synchronous generator works on the principle of …

Synchronous Speed

The synchronous speed is the speed of the revolution of the magnetic field in the stator winding of the motor. It is the speed at which the electromotive force is produced by the alternating machine. The Synchronous Speed is given by the relation shown below. The above equation (1) shows that the rotor speed N …
