Static
VAR Compensator (SVC)
•SVC are use for regulating
transmission voltage and for improving power quality of industrial load.
•SVC is made from one or more banks of
switched or fixed capacitor or reactor and thyristor controlled valve.
•SVC is a automatic impedance matching
device.
•SVC is connected in parallel with
transmission line.
•SVC is installed at the line ends or
at the midpoint transmission system.
•SVC have no rotating part except
internal switchgear.
•SVC is similar to asynchronous
condenser but with no rotating parts.
•The susceptance of SVC is controlled by thyristor valve.
•SVC is use to bring the power factor
closer to unity.
•SVC gives instantaneous response to
changes in the system.
