Role of DSTATCOM in distribution network with non-linear and active loads

The effectiveness of DSTATCOM in a distribution network with Field Oriented Control (FOC) induction motor drive as nonlinear load and wind turbine coupled with the asynchronous generator is examined. The above-mentioned FOC induction motor drive being nonlinear in nature introduces harmonics into the distribution network. Simulation of DSTATCOM based upon dqo transformation technique using PI controller has been performed in MATLAB/SIMULINK. The performance of DSTATCOM for both nonlinear load and active load is analyzed. DSTATCOM being connected in shunt with the distribution network injects compensating current into the network so as to provide compensation for the harmonics present in the source current.
