Fuse-based short-circuit protection coordination in shipboard DC integrated power systems considering arcing behavior
摘要
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.关键词
