a synchronous condenser is over excited synchronous motor under no load
Unlike a static condenser (capacitor bank), the value of reactive power from a synchronous condenser can be continuously adjusted. A synchronous condenser also has other advantages over static condensers such as: - not being affecting by harmonics (some harmonics can even be absorbed by a synch condenser) - producing no switching transients
A synchronous condenser is physically an electric generator/motor without a mechanical power source. Electrically a synchronous condenser changes the timing between rise and fall of current compared to voltage (phase angle). They also use stored energy to smooth small power fluctuations.
If a motor is spinning under no load, it is storing some energy in the rotating mass. This energy can be stored and released in the same way capacitors and inductors store and release energy. This is what a synchronous motor acting like a condenser is doing. The way it appears to the power system is dependent upon the field current applied to it. If used as a motor, this is controlled to keep it spinning at the desired speed under load. If used as a condenser, it is controlled to determine whether it will be releasing power ahead of or behind the power system (absorbing or releasing VARs).
mainly alternator,synchronous motor comes under the synchronous machine.a synchronous motor is not a self starting motor.if a synchronous motor moves with more than synchronous speed then it acts as a synchronous generator.
The main difference between synchronous generators and synchronous motors is that a synchronous generator supplies power. Otherwise, it would be just like a synchronous motor.
Synchronous
Synchronous motors are those that run only at Synchronous speed ie.. constant speed.
The Synchronous motor becomes a Synchronous generator when the speed of rotor increase from the rotating magnetic field of the stator.
By definition a synchronous generator must be synchronous. If it is not "locked in" it is not a synchronous generator, but an induction machine.
Liebig condenser, Vigreaux column, Snyder column, West condenser, Allihn condenser, Graham condenser, Dimroth condenser, Friedrichs condenser. There are no shortage of these!
