 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)
Shunt connected STATCOM
Series connected SSSC
