ABSTRACT
power flow can be flexibly controlled
Variety of FACTS controllers
UPFC – most interesting and versatile
INTRODUCTION TO FACTS
Power system today : largely mechanically controlled
low speed control
no frequent initiation of control
wear out quickly
uncontrolled dynamic and steady state operation
reduced security and quality of supply
INTRODUCTION TO UPFC
Proposed by : Gyugyi in 1991
Derived for real time and dynamic compensation
of ac transmission system
Provides multifunctional flexibility in power delivering industry
Unique ability to control power flow affecting parameters
Independently control real and reactive power flow
