Harmonic and Reactive Power Compensation with IRP Controlled DSTATCOM

摘要

The distribution system causes serious power quality problems with the more number of nonlinear loads. The nonlinear loads cause harmonics and reactive power problems. In this paper, a three-phase three-wire distribution static compensator (DSTATCOM) with instantaneous reactive power theory (IRP) control strategy is proposed for compensation of harmonics and reactive power problems. The proposed IRP-based control method is used to generate reference switching gate pulses for IGBT switches with a hysteresis control method. The proposed control technique using IRP improves the performance of the DSTATCOM under nonlinear voltage condition. The effectiveness of the proposed IRP theory-based three-phase three-wire DSTATCOM is investigated through MATLAB/Simulink.
