Abstract
Multi-pulse gate turn-off thyristor based voltage source converter (GTO-VSC) topology having a number of 6-pulse VSCs as elementary unit together with fundamental frequency mode of GTO gate control are widely used in STATCOM for dynamic reactive power compensation in electrical network. A 12-pulse topology generally produces an AC output voltage waveforms which contain 11th, 13th, etc. harmonics and hardly find its application due to higher total harmonic distortion (THD) level. In this paper, a new model of 2-level, 12-pulse, 132 kV, plusmn100 MVAr STATCOM employing 2times6-pulse GTO-VSCs, fundamental frequency gate switching, PI-control methodology, DC capacitor as an energy storage and two stages of magnetics, is designed and simulated to attenuate harmonics of the order of 5th, 7th, 11 th, 13th etc. by SimPowerSystems toolbox in MATLAB environment. The operating performance of the compensator is studied for regulating voltage and power factor correction in electrical network and results show the model acceptable for power system applications.
