What is the Static Var Compensator (SVC)?

The Siemens Static Var Compensator in the Radsted high-voltage switchgear station. Static Var Compensator is "a shunt-connected static Var generator or absorber whose output is adjusted to exchange capacitive or

Power Factor Correction (pfc) Tutorial

In theory capacitors could provide 100% of compensated reactive power required in a circuit, but in practice a power factor correction of between 95% and 98% (0.95 to 0.98) is usually sufficient. So using our coil from example no2 above, what value of capacitor is required to improve the power factor from 0.5 to 0.95.

what is the difference between Static Var Generator and Capacitor

Capacitor banks and Static Var Generator. Traditional capacitor bank response is stepped,which means there is almost always too little or too much compensation. A key advantage of Static Var Generator is the fact that it provides exactly the right amount of reactive power at all times. The reaction time of SVG is in the order of milliseconds

Variable capacitor

A variable capacitor is a capacitor whose capacitance may be intentionally and repeatedly changed mechanically or electronically. Variable capacitors are often used in L/C circuits to set the resonance frequency, e.g. to tune a radio (therefore it is sometimes called a tuning capacitor or tuning condenser ), or as a variable reactance, e.g

Static VAR Compensator

A static VAR compensator is a parallel combination of controlled reactor and fixed shunt capacitor shown in the figure below. The thyristor switch assembly in the SVC controls the reactor. The firing angle of the thyristor controls the voltage across the inductor and thus the current flowing through the inductor. In this way, the reactive power draw by the inductor can be controlled.
