Mitigation of Voltage and Current Variations Due To Three Phase Fault in a Single machine system Using Distributed Power Flow Controller ABSTRACT: The Power quality issues like voltage variations and current variations presented in the electrical networks are due to the consumer’s utilities. Which are non – linear in nature. These non – linear loads inject increased flow of currents and reduced voltages with distortions. These voltage and current variations cause adverse effect on the consumer utilities. To overcome this problem we are using a modern Flexible Alternating Current Transmission System controller i.e. distributed power flow controller. This controller is also similar to any other series and shunt controllers like UPFC. In the present controller i.e. in DPFC, the common Dc link capacitor presented in UPFC is eliminated and three single phase converters are used in place of three phase series converter. In this paper we have implemented DPFC for a single machine connected to a three phase load under three phase fault environment. Observed the voltage and current variation suppression in a significant way. The control circuit is formulated using shunt currents and series referral voltages. The entire system is designed and analyzed using MATLAB/SIMULINK.
