OBJECTIVE  The 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 FACTS  FACTS 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)
