  1. Interline Unified Power Quality Conditioner Presented by Siddhartha Dakua Priyanka Panda Ansuman Mahapatra Chetan Nayak ShyamalenduMahapatro Guided by Mr.P. Naresh Asst.Professor (Dept.EEE)

  2. CONTENTS • Objective • Overview of FACTS • Structure of IUPQC controller • Typical IUPQC connected in distribution system • Function of D-STATCOM • Function of DVR • Schematic structure of VSC • Simulink model without UPQC • Simulation results of voltage and current • Pwm technique

  3. 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.

  4. 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)
