Multilevel converter based DSTATCOM for –ve sequence component of current reduction and harmonic mitigation

This paper defines the performance enhancement of multilevel converter based hybrid filter. The utilization of hybrid DSTATCOM in distribution system reduces the reactive power conjunction, harmonic mitigation and -ve sequence component reduction. The hybrid DSTATCOM can injects load current harmonics in -ve direction and it was injects -ve sequence component in opposition with currents flowing in neutral line. The proposed system introduces multilevel converter in hybrid DSTATCOM will reduces filtering requirement and enhances its rating of compensation by distributing stress on power electronic devices.
