The 48-Pulse VSC-Based Generalized Interline Power-Flow Controller (GIPFC)

  • Amir Ghorbani Azad University, Abhar Branch, Abhar, Iran.


The generalized interline power-flow controller (GIPFC) is a voltage-source controller (VSC)-based flexible ac transmissionsystem (FACTS) controller that can independently regularize the power-flow over each transmission line of a multiline system.This paper presents a modeling and performance analysis of GIPFC based on 48-pulsed voltage-source converters. Thispaper deals with a cascaded multilevel converter model, which is a 48-pulse (three levels) source converter. The voltagesource converter described in this paper is a harmonic neutralized, 48-pulse GTO converter. The GIPFC controller is basedon d-q orthogonal coordinates. The algorithm is verified using simulations in MATLAB/Simulink environment. Comparisonsbetween Unified Power Flow Controller (UPFC) and GIPFC are also included.
