Abstract :
The Distribution STATic COMpensator (DSTATCOM) has proved to be a useful custom power device to eliminate harmonic components and to compensate reactive power for balanced/unbalanced linear/nonlinear loads. This paper presents a novel approach to calculate the reference compensation current of three phase DSTATCOM under distorted utility condition at instantaneous state. The proposed approach is compared with reviewed control strategies viz. instantaneous p-q theory, synchronous reference frame Method(SRF), Modified SRF Method(MSRF), instantaneous symmetrical component theory(ISCT) and Average unit power factor theory(AUPFT) for different three conditions. The performance of the system simulated in Matlab Platform and evaluated considering the source current total harmonic distortion. The result shows the Proposed Method has improved system performance as compared to others.
