How much does a synchronous condenser cost?
Normally, the mean cost for a synchronous condenser is between $10 to $40 per kVAR and the maintenance cost ranges from about $0.4 to $0.8/kVAR per year.
What does a synchronous condenser do?
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).
Where are synchronous condenser installed?
Installed at strategic intervals along a transmission system, synchronous condenser systems are either new electrical rotating equipment or existing turbogenerators reconfigured to perform as reliable grid stabilizers.
What is the benefit of synchronous condenser?
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 is the difference between synchronous motor and synchronous condenser?
The only difference between a synchronous motor and a synchronous condenser is the synchronous condenser shaft is not connected to anything—it simply spins unimpeded. The sole purpose of a synchronous condenser is to adjust conditions (power factor) on the electric power transmission grid.
What is synchronous condenser PDF?
A synchronous condenser (SC) is a synchronous generator operating. without a prime mover. Reactive power output regulation is performed by. regulating the excitation current. Synchronous condensers have been extensively used for voltage control.
Is a synchronous condenser a generator?
Synchronous condensers are considered as motors without any connected load or generators without prime movers. They produce or absorb reactive power.
Why is it called a synchronous condenser?
When the motor is operated at no load with over-excitation, it takes a current that leads the voltage by nearly 90 degrees. Thus, it behaves like a capacitor and under such operating conditions, the synchronous motor is called a synchronous capacitor.
Where are synchronous condenser used?
The synchronous condenser is used in power lines to improve power factor, power factor correction by connecting it along with transmission lines.
What are the disadvantages of synchronous condenser?
(i) There are considerable losses in the motor. (ii) The maintenance cost is high. (iii) It produces noise.
Is synchronous motor self induced?
Above a certain size, synchronous motors are not self-starting motors. This property is due to the inertia of the rotor; it cannot instantly follow the rotation of the magnetic field of the stator.
