OBJECTIVEThe Objective of this Project is to improve the Power Quality of feeders in a distribution system by using IUPQC.

To enhance the power transfer capability in an existing feeder.

To change power flow under dynamic conditions. Overview of FACTSFACTS controllers can be classified as Variable impedance type Voltage Source Converter (VSC) based.The variable impedance type controllers SVC(Static VAR compensator) TCSC(Thyristor controlled series compensator) TCPST(Thyristor controlled phase shift transformer) The VSC based FACTS controllers STATCOM(Static synchronous compensator) DVR(Dynamic voltage restorer) SSSC(Static synchronous series compensator) IPFC(Interline power flow controller) UPFC(Unified power flow contoller) UPQC(Unified power quality conditioner)IntroductionShunt connected STATCOMSeries connected SSSCShunt and Series connected UPFC
