Mitigation of Fault in the Distribution System by using Flexible Distributed Static Compensator (FD-STATCOM)
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 4
Abstract
This paper proposes a flexible D-STATCOM (Distribution Static Compensator) and its new controller system, that be able to mitigate all types of faults (LG, DLG, LL, LLL and LLLG), and improve the distribution system performance. This paper validates the performance of D-STATCOM system to mitigate the power quality problems such as voltage flickers, voltage sags/swells harmonics and improve the distribution system performance under all types of system related disturbances and system unbalanced faults (LG, LL, DLG), balanced faults (LLL and LLLG). A 12-Pulse converter based STATCOM was used to mitigate the voltage flicker with respect to the harmonic problem. A multilevel converter has several advantages over a conventional 12-pulse converter such a Staircase waveform quality, Common-mode (CM) voltage, Input current and harmonic control. Multi level based D-STATCOM configuration with IGBT is designed and the graphic models of the D-STATCOM is developed using the MATLAB/SIMULINK
