ABSTRACT

Nowadays, a large number of ships utilize DC power plant propulsion systems. In the past, the selective protection of power systems in AC power propulsion system ships was generally achieved by selecting circuit breakers based on the short-circuit current calculation results and by setting the circuit breakers accordingly. For DC power plant propulsion systems, due to the extensive use of current-limiting protective devices, the peak short-circuit current is related not only to system parameters but also to the selection and characteristics of the protective devices. Protective selection in DC power plant propulsion systems is crucial for maritime safety. This paper elucidates the principles of selective protection during short circuits, proposes a selective protection design method, analyzes a selective protection scheme using a specific vessel as an example, and finally presents a modeling and simulation approach. This paper can serve as a reference for the design of selective protection in similar DC power plant propulsion systems. By selecting appropriate fuses and using selective protection analysis methods, system safety can be improved.
