Multi-Level Current Reinjection CSC for STATCOM Application

A multi-level current reinjection concept, already shown to provide acceptable harmonic reduction with fewer switching components than the conventional multi-level schemes, is described in this paper with reference to its performance when operated as a STATCOM. PSCAD/EMTDC is used to illustrate the steady state and fast dynamic response to system changes, both under symmetrical and asymmetrical terminal voltage conditions.
