Short Circuit Protection Design of DC Power System on Board
With the development of energy-saving and environmental protection concepts in the field of ships and offshore,as well as the widespread application of new energy in ships,the DC power distribution system has gained popularity among ship owners due to its high efficiency,energy saving,and good compatibility.However,due to the limited capacity of DC circuit breakers and their high costs,the construction of DC circuit breakers is different from that of AC circuit breakers,resulting in a completely different short-circuit protection design for DC power distribution systems compared to AC systems.Based on the successful case of short-circuit protection design for a wind power installation platform using a DC power distribution system,the structure of DC circuit breakers and presents the method and key points for short-circuit protection design of DC distribution systems on ships are analyzed.Reserch results can provide some references for the application of DC distribution systems on ships.
