Implementation of Distributed Power FlowController to advance Power Quality

Abstract

In the last few decades the usage of electric power  is increasing day by day, the operation of powermethods has become complex because of developing consumption and multiplied quantity of non-linear loads because of whichcompensation of a couple of power great issues has grow to be a compulsion. As a consequence the power organizations areconcentrating no longer only on variety of the power but additionally the quality of the power with develop in complexity in method.Right here the brand new element within the flexible AC-transmission system (FACTS) household, called distributed power-flow controller (DPFC) is offered in this paper. The important power exceptional problems like voltage sag and swell are studied inthis paper. The DPFC is modified from UPFC, by way of taking away normal DC hyperlink between series and shunt convertersfrom UPFC. The three-phase sequence converter is cut up into number of single-segment series dispensed converters throughthe line. The energetic energy is exchange between the series and shunt converter at third harmonic frequency by way oftransmission line in DPFC.The model of transmission line with andwithout DPFC is modelled in MATLAB/Simulink. From the model, it is seen that the power quality improved with thehelp of DPFC with higher controllability and reliability compare to other FACTS devices.
