Power quality is certainly a major concern in the present era. This paper proposes a flexible D-STATCOM with a new controller scheme. And it supplies power to sensitive loads under Islanding conditions. This paper introduces the performance of FD-STATCOM system to mitigate power quality problems under all types of system related disturbances such as L-L &DLG faults. A 12 pulse IGBT based D-STATCOM is designed using Matlab. Here the super capacitor is used as the storage device. The reliability of the control scheme in the system response to the voltage disturbances caused by LL&DLG faults and Islanded operating conditions are obviously proved in the simulation results.
