An analogy of VSC with MMC topology for HVDC application

Abstract

This paper deals with the detailed description and understanding of the effect of an HVDC system when VSC and MMC are used. It describes the working principle of each type and its comparison when applied to a HVDC system. Steady state and transient analysis has been done and its results have been discussed in detail.. It also gives an idea of the harmonic changes done by FFT analysis. The simulation has been carried out using PSCAD/EMTDC software. The results are given accordingly.
