Three-phase multi-pulse converter StatCom analysis

This paper is aimed to present the analysis of operating characteristics of the static synchronous compensator (Statcom) based on a multi-pulse voltage-source inverter (VSI). A detailed analysis of voltages and currents on both 6- and 12-pulses is presented and equations describing the performance of each circuit are derived. Finally a comparison between digital simulations using the EMTDC/PSCAD and analytical results is shown, verifying the validity of the derived expressions. The device is now being implemented in the laboratory, based on IGBT's.
