Improvement in Power Quality in Power system Through of DPFC

In this paper a new member of FACTS family Distributed Power Flow Controller has been discussed. DPFC originates from unified power flow controller (UPFC). DPFC can be treated as UPFC as both have shunt and series controller beside the main difference in size and number of converter. DPFC maintains the terminal voltage constant by regulating the DC link voltage. As the D-FACTS converters are single-phase and floating with respect to the ground and no need for isolating the high voltage as in case of UPFC. DPFC has two control circuits for both series and shunt controller. Shunt controller uses classical PI controller and in shunt controller synchronous d-q-0 based controller is used. The effectiveness of DPFC is proved by MATLAB/Simulink model. The results shows that the DPFC can effectively compensate the harmonics and maintain the voltage level at the load terminals.
