SVC stands for________________
Static Voltage Controller
Stabilility Voltage Control
Static VARContoller
Stability Voltage Ampere Reactive Controller
Static VARContoller
SVC stands for Static VAR Compensator (often colloquially referred to as Static VAR Controller). It is a key shunt-connected Flexible AC Transmission System (FACTS) device used to regulate voltage, improve power factor, and enhance stability in power transmission networks.

An SVC maintains bus voltage by absorbing or injecting reactive power (Q) into the system. It consists of a Thyristor-Controlled Reactor (TCR) to absorb reactive power and a Thyristor-Switched Capacitor (TSC) to generate reactive power. By varying the firing angle of the thyristors, the SVC provides continuous control of the effective shunt impedance, thereby stabilizing the voltage profile under varying load conditions.
SVC is a shunt FACTS device used for fast reactive power compensation.
It provides continuous voltage regulation by adjusting firing angles (╬▒).
It helps in increasing the power transfer capability of long transmission lines.
The TCR provides variable inductive reactance, and TSC provides step-wise capacitive reactance.
Fast response time compared to mechanical switching.
Smooth and continuous control of reactive power.
Improves transient stability and voltage profile.
Generates harmonics due to thyristor switching.
Requires complex control circuits and cooling systems.
Does not provide real power (active power) compensation.
Voltage regulation at load centers.
Damping power system oscillations.
Improving voltage stability in industrial plants with fluctuating loads (e.g., arc furnaces).
While the question uses 'Controller', the industry standard term is 'Static VARCompensator'.
Option A and B are technically incorrect as they do not describe the reactive power compensation nature of the device.
C is correct тАФ SVC stands for Static VAR Compensator, which regulates transmission line voltage by injecting or absorbing reactive power.
Always remember that FACTS devices like SVC, TCSC, and STATCOM focus on either shunt (voltage) or series (impedance) compensation to control power flow.
