dc.description.abstractIn the maritime domain, the efforts to reduce the emission of greenhouse gases move industry towards highly efficient vessels with DC distribution technologies. These new power systems, however, come with technical challenges in protection coordination which is necessary to minimise the impact of the system fault. This paper presents benefits and protection difficulties of DC shipboard power systems, and current protection schemes, commercially available, with three different classification: bus protection with solid-state bus-tie breakers, feeder protection with high-speed fuses and generator-rectifier fault blocking functions. In addition, two new protection methods recently proposed are introduced: additional bus capacitance for the bus protection and artificial short-circuit for the generator-rectifier protection. Lastly,  possibility of a modular multi-level converter for the DC shipboard power systems is discussed with its pros and cons.
