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 attention 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.
