Synchronous condenser Working and Application

In this article we will know about synchronous condenser working and application. From this article we will also know that what is introduction of synchronous condenser.

Synchronous condenser working and Application

Now we are going to study about synchronous condenser working and application .

Synchronous condenser working and Application

Synchronous motors load the power line with a leading power factor. This is often useful in cancelling out the more commonly encountered lagging power factor caused by induction motors and other inductive loads. Originally, large industrial synchronous motors came into wide use because of this ability to correct the lagging power factor of induction motors.

This leading power factor can be exaggerated by removing the mechanical load and over exciting the field of the synchronous motor. Such a device is known as a synchronous condenser. Furthermore, the leading power factor can be adjusted by varying the field excitation. This makes it possible to nearly cancel an arbitrary lagging power factor to unity by paralleling the lagging load with a synchronous motor. A synchronous condenser is operated in a borderline condition between a motor and a generator with no mechanical load to fulfill this function. It can compensate either a leading or lagging power factor, by absorbing or supplying reactive power to the line. This enhance power line voltage regulation .since a synchronous condenser does not supply a torque, the output shaft may be distend with and the unit easily enclosed in a gas tight shell. It is describe title which is synchronous condenser working and application.
The synchronous condenser may then be filled with hydrogen to aid cooling and reduce wind age losses. Since a synchronous condenser does not supply torque, the output shaft may be dispensed with the unit easily enclosed in a gas tight shell. The synchronous condenser may then be filled with hydrogen to aid cooling and reduce wind age losses. Since the density of hydrogen is 7% of that of air, the wind age loss for hydrogen filled unit is 7% of that encountered in air. Furthermore, the thermal conductivity of hydrogen is ten times that of air. This, heat removal is ten times more efficient. As a result a hydrogen filled synchronous condenser can be driven Harper than an air cooled unit, or it may be physically smaller for given capacity. There is no explosion hazard as long as the hydrogen concentration is maintained above 70% , typically above 91% . the efficiency of long power transmission lines may be increased by placing synchronous condenser along the line to compensate lagging currents caused by line inductance. More real power may be transmitted through a fixed size line if the power factor is brought closer to unity by synchronous condensers absorbing reactive power. The ability of synchronous condensers to absorbs or produce reactive power on a transient basis stables the power grid against short circuit and other transient fault conditions. Transient sags and dips of milliseconds duration are stabilized. This supplements longer response times of quick acting voltage regulation and excitation
of generating equipment. The synchronous condenser aids voltage regulation by drawing leading current when the line voltage sags, which increases generator excitation there by resorting line voltage. a capacitor bank does not have this ability. It is main synchronous condenser working and application.

The capacity of a synchronous condenser can be increased by replacing the copper wound iron field rotor with iron less motor of high temperature superconducting wire, which must be cooled to the liquid nitrogen boiling point of 77 degree kelvin (-196 degree Celsius). The superconducting wire carries 160 times the current of comparable copper wire, while producing a flux density of 3 tussles or higher. An iron core would saturate at 2 tussles in the rotor air gap.It is basic synchronous condenser working and application .
