This paper proposes a comprehensive compensation strategy for DSTATCOM which is suitable for both reactive power compensation and harmonic elimination in distribution network. The DSTATCOM is connected with the transformer taps on the high voltage (HV) windings and the transformer adopts the Dyn11 connection group. Firstly, according to the converter model, the decoupled control strategy is presented for the independent control of the active and reactive current components. Then, the detection method of reactive command current and harmonic command current is analyzed. Conventional PI controller and quasi-PR controller are adopted respectively for the control of the reactive current and harmonic current. Simulation test results based on MATLAB/SIMULINK show that the proposed control strategy has a good performances.
