Power Converter Architecture

A static VAR compensator (var is defined as volt ampere reactive) is a set of electrical devices for providing fast-acting reactive power on high-voltage electricity transmission networks. SVCs are part of the Flexible AC transmission system device family, regulating voltage, power factor, harmonics and stabilising the system. Unlike a synchronous condenser which is a rotating electrical machine, a static VAR compensator has no significant moving parts (other than internal switchgear). Prior to the invention of the SVC, power factor compensation was the preserve of large rotating machines such as synchronous condensers or switched capacitor banks.
SVC is composed of two components.
• Harmonic Filters :
They are composed of capacitors and coil tune for different harmonics. For LHC, we have 5 filters for harmonics 5, 7, 11, 13 and 22. The SPS filters take 21MVar from network
