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

open access: yesMathematics, 2022
Existing studies show that several performance issues will arise in the HVDC link during the three phase-to-ground fault at the side of the inverter and that the DC voltage will oscillate around zero and will not affect the rectifier of the AC system ...
