Study on fault of voltage source converter HVDC with MMC Technology

Voltage source converter (VSC) technologies present a bright opportunity in a variety of fields within the power system industry. Modular multilevel converter (MMC) technology is expected to supersede two level and three level VSC technologies for HVDC applications due to their advantages in terms of scalability, performance, and efficiency. The paper deals with fault study of VSC HVDC with MMC technology. The study is to compare theoretical analysis with PSIM based simulation result, to evaluate converter overcurrent performance, and to provide tool for optimization factors to overcurrent. Comparative analysis with the existing averaged and detailed model MMC simulation using other software as Matlab Simulink and PSCAD are presented for validity and evaluation of the simulations.
