Marvelous Synchronous Condenser Diagram

A synchronous condenser or a synchronous compensator is a synchronous motor running without a mechanical load.

Synchronous condenser diagram. It is based on a double fed machine with a conventional three. For major power network we use synchronous condensers for the purpose but for comparatively lower rated systems we usually employ capacitor bank. The adjustable speed synchronous condenser is not exactly a facts compensator as it contains an electric machine.

Synchronous capacitor or synchronous condenser phasor diagram. It is started up and stopped with a frequency controlled electric motor pony motor or a starting frequency converter. 1 1 disadvantage of low power factor.

However it may be an interesting shunt device to compensate reactive power continuously and relatively large amounts of active power for a short time. In previous years these motors were only used for p f improvements of the system not to run a load. The siemens synchronous condenser solution comprises a horizontal synchronous generator connected to the high voltage transmission network via a step up transformer.

The phasor diagrams of synchronous motor working in over excited conditions without any load shown below. The kinetic energy stored in the rotor of a synchronous condenser contributes to the total inertia of the power system and is thus also beneficial from a frequency control perspective. Synchronous condenser can support the power system voltage during prolonged voltage sags by increasing the network inertia.

Synchronous condensers also called synchronous capacitors or synchronous compensators are traditional synchronous machines which work as motors without an active load and are able to provide both reactive power and inertia to the grid. It can generate or absorb reactive volt ampere var by varying the excitation of its field winding. A synchronous motor bought to run a load can be functioned overexcited to deliver reactive power q for an electrical system.

They can therefore be utilized as var compensating devices in situations where voltage. This is shown in the phasor diagram fig. The synchronous condenser is the more advanced technique of improving power factor than a static capacitor bank but power factor improvement by synchronous condenser below 500 kvar is not economical than that by a static capacitor bank.
