Selective protection analysis of DC integrated electric propulsion system for hybrid electric ships
As an effective design solution to reduce ship emissions,hybrid power systems have received increasing at-tention and favor.To ensure the safety of the ship's power system,it is necessary to conduct selective protection analysis for the integrated electric propulsion system to achieve protection for personnel,equipment,and ships.Taking a hybrid tugboat as an example,this paper analyzes the design concept of selective protection for DC integrated electric propulsion system,models key components of the system,constructs a system fault simulation model,and verifies reliability through actual ship tests,providing reference for the design of similar ships.
