Interline Unified Power Quality Conditioner Presented by Siddhartha Dakua Priyanka Panda Ansuman Mahapatra Chetan Nayak Shyamalendu Mahapatro Guided by Mr.P. Naresh Asst.Professor (Dept.EEE) Slide 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 Slide 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. Slide 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) Slide 5 Introduction Shunt connected STATCOM Series connected SSSC Shunt and Series connected UPFC Slide 6 Structure of IUPQC Controller Slide 7 Typical IUPQC connected in a distribution system.
