Abstract

This paper presents a control scheme of cascaded H-bridge SSSC in three-phase power systems. By this method, the SSSC can control output current almost freely. But it needs wide margin of dc voltage under large power system voltage unbalance. To avoid this, we exclusively use the two methods depending on the extent of voltage unbalance. Solving this problem, a technique using zero sequence voltage and negative-sequence current is proposed. By this scheme, the SSSC is allowed to operate under asymmetrical conditions by power system faults. The validity is examined by digital simulation under one line and two-lines fault circuit condition.
