Abstract

This paper is focused on design and modeling of a new fundamental frequency switching based 24-pulse 2-level plusmn100 MVAR STATCOM in Matlab platform for high power applications. Only four 6-pulse elementary gate turn off voltage source converters (GTO-VSC) along with single stage magnetics meeting dual objectives of magnetic summing circuit and coupling transformer at PCC, and PI-controllers employing principle of phase angle control, are modeled to achieve an improved performance to regulate load voltage in an AC network with THD values within limits.
