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)
