摘要：In this paper, an operation methodology of a STATCOM (Static Synchronous Compensator) is proposed for reduction in Total Harmonic Distortion (THD) in power systems. For achieving this objective a comparison is made between two different configurations of Statcom.One is made up of two sets of three-level 12-pulse converter considering magnetic saturation and other is made up of two sets of three-level 12-pulse converter without magnetic saturation .The reactive power is controlled by the phase angle difference between the two sets of three-level 12-pulse VSC’s. The magnetic saturation of transformers used in VSC topology results in increased THD. As per IEEE standard, in new configuration THD is reduced .The proposed model of the STATCOM is connected to a 33kV, 50Hz system and Fast Fourier Transform (FFT) results are presented for demonstrating its performance.
