Abstract: In this paper, a 24-pulse three-level ±100 MVAR STATCOM (static synchronous compensator) is evolved employing 4 × 6-pulse NPC GTO-VSCs (neutral point diode clamped gate-turn-off thyristor based voltage source converters) with magnetics optimised to a single stage. Through an angle control, the magnitude and phase angle of the STATCOM voltage is controlled with a pre-calculated dead angle in d-q synchronously rotating frame. While the performance of STATCOM is simulated in MATLAB platform for the voltage control in transmission system, its operating characteristics in respect of system dynamics and harmonics distortion are observed analogous to that of a conventional 48-pulse STATCOM. It has emerged to be cost effective topology of STATCOM.
