摘　　要：混合动力系统作为一种有效降低船舶排放的设计方案,受到了越来越多的关注和青睐。为确保船舶电力系统的安全性,则需要针对综合电力推进系统进行选择性保护分析,以实现对人员、设备、船舶的保护。以某混合动力拖轮为实例,分析直流综合电力推进系统选择性保护设计思路,针对系统关键元件进行建模,构建系统故障仿真模型并实船试验验证可靠性,为同类型船舶相关设计提供参考。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.
