Improvement of Voltage Profile By 84-Pulse VSC Configuration Using Multi-Level Converter Using STATCOM

K. V. Soumya, P. Gayathri

In this work; the Static Synchronous Compensator (StatCom) is one of the most useful FACTS devices; since it can synthesize the reactive power from small storing elements. By regulation of the StatCom?s output voltage magnitude; the reactive power exchange between the device and the transmission system may be controlled to improve the power system voltage profile .Since the StatCom may cause interference on the system?s fundamental sine wave at frequencies that are multiples of the fundamental one; special care should be taken to ensure not to pollute the system to prevent further harmonic issues. In general; there are three feasible strategies to assemble a VSC: (i) the multi-pulse; (ii) the multi-level; (iii) and the pulse width modulation. Strong efforts have been made in order to reach minimum harmonic distortion in the VSC?s output voltage. This paper analyzes the structure of an 84-pulse voltage source converter (VSC); assembled by combining one twelve-pulse VSC; in conjunction with an asymmetric single phase seven-level converter plus an injection transformer.. With this arrangement; the VSC output's total harmonic distortion in voltages is reduced; allowing it to be used in special applications The results found that the proposed strategy allows savings in the number of employed switches.
