| 摘要: |
| 针对保护电器开断特性对船舶直流综合电力系统短路故障保护快速性和选择性的影响，提出了一种考虑熔断器燃弧的 DC IPS 短路故障保护建模与整定方法。首先，基于 Cassie 模型描述熔断器的燃弧过程，并结合试验数据，采用遗传算法确定了模型参数的变化规律。其次，将 DC IPS 的短路特性映射到熔断器试验回路中，构建了适应不同熔断器选型的 DC IPS 短路故障保护全过程模型。然后，依据中国船级社标准构建约束条件，以实现 DC IPS 短路故障保护的快速性和选择性为目标，提出了 DC IPS 熔断器的整定方法。最后，通过案例 DC IPS 短路故障等效实验，以及未计及燃弧的熔断器选型结果的对比实验，验证了方法的有效性。该熔断器保护协调方法能够兼顾短路故障保护的选择性与快速性，案例 DC IPS 的短路电流在 2 ms 内被抑制到极低值。 |

| Abstract: |
| To address the impact of protective device breaking characteristics on the speed and selectivity of short-circuit fault protection in shipboard DC integrated power systems (DC IPS), a modeling and coordination method that incorporates fuse arcing behavior is proposed. First, the arcing behavior of the fuse is modeled based on the Cassie arc model, and the parameter variations are identified through genetic algorithm optimization using experimental data. Second, the short-circuit characteristics of the DC IPS are replicated within a fuse test circuit, enabling the development of a comprehensive short-circuit protection model adaptable to different fuse selections. Then, based on the standards of the China Classification Society, constraint conditions are formulated, and a fuse coordination method is proposed to ensure both rapid and selective fault protection. Finally, the effectiveness of the proposed method is validated through equivalent short-circuit fault experiments on a case-study DC IPS, as well as comparation with the fuse selection results that do not consider arcing behavior. The results indicate that the proposed fuse coordination method successfully balances protection speed and selectivity, with the short-circuit current in the case-study DC IPS suppressed to a very low level within 2 ms. |
