Abstract

The paper presents a tutorial review of the basic operation, control functions and steady state performance of a Unified Power Flow Controller (UPFC). A typical circuit arrangement of a UPFC is given and principles of controlling active and reactive powers are described. The main functions of UPFC are analyzed; including voltage regulation, series reactive compensation, phase compensation, and combined actions. A simplified two-bus power system is considered to demonstrate the main effects of the UPFC. Studies and results are presented to show the wide range capabilities of the UPFC in controlling transmission active and reactive powers simultaneously and/or independently.
