Design and Implementation of New DPFC To Control Power Quality

Author(s): K. S. Srikanth

A new control scheme to improve and maintain the power quality of an electrical power system i.e. distributed power flow controller. Generally, In case of modern power utilities have problems like challenges in growth of electricity in case of non-linear loads in grid connected systems. In this paper, we introduced a new series-shunt type FACTS controller called as distributed power flow controller. This DPFC method is same as the UPFC used to compensate the voltage sag and the current swell. In DPFC, we eliminate the common dc link capacitor and instead of single three phase series converter it has three individual single phase converters. In this paper, the control circuit is designed by using series referral voltages and branch currents. The evaluated values are obtained by using MATLAB/SIMULINK.
