What are advantages and disadvantages of synchronous condenser?

(i) By varying the field excitation, the magnitude of current drawn by the motor can be changed by any amount. This helps in achieving step less control of power factor. (ii) The motor windings have high thermal stability to short circuit currents. (iii) The faults can be removed easily.

What is the advantage of synchronous current?

One of the major advantage of using synchronous motor is the ability to control the power factor. An over excited synchronous motor can have leading power factor and can be operated in parallel to induction motors and other lagging power factor loads thereby improving the system power factor.

Which among these is the advantage of synchronous condensers Mcq?

Which among these is the advantage of synchronous condensers? a. Helps in achieving the stepless control of power factor.

What are some of the advantages of a synchronous condenser over static condensers to regulate transmission line voltage?

One advantage is the amount of reactive power from a synchronous condenser can be continuously adjusted. Reactive power from a capacitor bank decreases when grid voltage decreases, while a synchronous condenser can increase reactive current as voltage decreases.

What are the advantage of synchronous motor?

The advantages of the synchronous motor are the ease with which the power factor can be controlled and the constant rotational speed of the machine, irrespective of the applied load. Synchronous motors, however, are generally more expensive and a d.c. supply is a necessary feature of the rotor excitation.

What is the advantage of the static capacitor?

This compensation system is optimal for balanced systems and to compensate loads with connection and disconnection rates that are not too fast, on the order of seconds, and it is currently the most common system in most installations despite increasing numbers of unbalanced installations.

Which among these is the major advantage of per unit computations?

Per unit impedance of transformers is the same referred to either side of it. b. For simulating steady state and transient models in the computer this method is very useful.

What is the best effect of synchronous condenser?

A synchronous condenser provides step-less automatic power-factor correction with the ability to produce up to 150\% additional vars. The system produces no switching transients and is not affected by system electrical harmonics (some harmonics can even be absorbed by synchronous condensers).

What is the advantage of synchronous compensator?

Advantages of synchronous condenser: The reactive power can be adjusted continuously. They are giving better performance than the static capacitor in the high voltage system. Maintenance-free. A high degree of safety can be maintained.

What are the advantages of synchronous condenser over static capacitor bank?

The benefits of a synchronous condenser are that we can control the power factor of the system smoothly without stepping as per demand. In the cause of a static capacitor bank, this fine adjustments of power factor cannot be possible rather a capacitor bank improves the power factor stepwise.

Why add synchronous condensers to your power system?

Adding synchronous condensers can help with reactive power needs, increase short-circuit strength and thus system inertia, and assure better dynamic voltage recovery after severe system faults. If you thought that the synchronous condenser was an antiquated relic of the past, think again!

Are synchronous condensers worth the capital investment?

While costs of synchronous condenser installations do vary, overall capital investment appears to be comparable to both SVC and STATCOM. Inertia 1 may also become an important concern in the not-too-distant future.

What are the advantages of a synchronous motor?

The main advantage of using the synchronous motor is that the improvement of the power factor is smooth. When a synchronous motor operates with over-excitation, it draws leading current from the supply. We use this property of a synchronous motor for the purpose.
