Effect of system parameters when fuse blows in High Voltage Direct Current (HVDC) power supply systems

In this thesis, we discuss the effects of system parameters on a high voltage direct current (HVDC) power supply system when a fuse blows. We then use a new fuse model which we have created, to simulate voltages and currents when a fuse blows and evaluate the risks that other Information and Communications Technology (ICT) equipment will fail, or that fuses in the equipment will also blow. From these results, we create a risk map, and offer measures that can be used for construction of electrically safe systems.
