Using Matlab/Simulink Software Package to Investigate Fault Behaviors in HVDC System

Existing studies show that several performance issues will arise in the HVDC link during three phase-to-ground fault at side of inverter and DC voltage oscillate around zero not affect rectifier AC system though system, voltages become currents high amplitude as well minor disturbances. It has also been argued when is applied on a single-phase to ground side, decrease. In this paper, we focus single line-to-ground fault, double their behavior with detailed simulations. A direct current (HVDC) Monopolar modeled using Matlab/Simulink software package for research. The results inverter, increase bogus waveform collapse zero.At level, experience an while different At remain stable state both voltages.
