دانلود Dynamic Modeling and Control of UPFC for Power Flow Control

Abstract

Unified Power Flow Controller can control the power system parameters like voltage, line reactance and phase angle to control power flow in the transmission line .The control of power flow in the transmission line done by injecting a suitable voltage  with a phase angle. In this paper design a decoupled control scheme  for shunt and series converter to track the reference power inputs by using conventional PI controller. Modeling is done by using MATLAB/SIMULINK  software.  The  analysis  is  done  on  the  system  with  different  power  factors  and  load  conditions.  The  results  show  that  UPFC  is  able  to  track  the  power  changes  and  inject  a  suitable  voltage  into  the power system so that power flow can be maintained.
