Normally induction motors connected to a stiff source cannot be protected from voltage disturbances in a distribution system using a distribution static compensator (DSTATCOM). A normal DSTATCOM can operate either in Voltage Control Mode (VCM) or Current Control Mode (CCM). When an induction motor operated under stiff source may get faults either from voltage disturbances or current disturbances. To solve this, a new control algorithm is proposed to make as multifunctional i.e, operated in VCM under stiff source and CCM in normal operation. From this, a fast voltage regulation is achieved at the load terminal and protects induction machine drive system during voltage disturbances and current disturbances. In this paper major power quality faults i.e, sag is injected and compensated using multifunctional DSTATCOM. The complete project is carried out using MATLAB/SIMULINK.
