Implementation of Cascaded H Bridge Control Scheme for SSSC using Zero Sequence Voltage and Negative Sequence Current

Abstract

This paper focuses on a control scheme of cascaded H bridge scheme implemented in SSSC for enhance the three phase power systems. Cascaded H bridge based SSSC has offer low switching losses and less total harmonics distortion, and reduces the number of circuit components. Each H bridge cell has isolated dc capacitors which is exist balanced capacitor voltages. Since SSSC is often requested to operate under asymmetrical condition by power system faults such as one line grounding or two line short circuit and it can be the control output current almost freely. Cascaded H bridge based SSSC needs wide range of margin of dc voltage for operates in large unbalanced voltage power system. This proposed system focused on to avoids wide range of margin of dc voltage by exclusively using the two methods such has zero sequence voltage and negative sequence current. By this scheme, the SSSC is allowed to operate under asymmetrical condition by power system faults. The validity is examined by digital simulation under one line and two line fault in power system.
