大型船舶电力系统快速拓扑分析新方法

A fast topology analysis method for large shipboard power system network

为应对现代船舶朝着大型化、自动化发展的同时对船舶电力系统网络拓扑监控能力提出的更高要求,本文提出一种大型船舶电力系统快速拓扑分析的新方法。首先,利用图论拓扑信息数据模式将船舶电网拓扑信息录入系统;其次,遍历初始网络拓扑形成母线,基于独岛搜索策略形成电气岛,完成静态分析并生成拓扑信息数据库;最后,利用节点标记法对受影响的母线进行连通性分析,并结合独岛搜索策略,实现船舶电力系统拓扑结构的动态更新。对某现代化大型集装箱船舶电力系统进行验证分析表明,本文方法结构简便易于实现、满足现代大型船舶电力系统拓扑分析的实时性与有效性需求。

In response to the increasing demand on the shipboard power system topological monitoring ability with the rapid development of modern ship toward large-scale and automation, this paper presents a novel fast topology analysis method for large shipboard power system. Firstly, input the shipboard power system topological information using the graph theory based data model; Secondly, traverse the initial network and generate the node bus and island to achieve the static global topology analysis, then generate the topological information database; Finally, after analyzing the connectivity of the affected node bus with the node marking algorithm, the dynamic tracking program is completed combining with the proposed isolated island search strategy. Verification and analysis is conducted on a modern large shipboard power system, the results indicate that the proposed fast topology analysis method fulfills the demands of modern large shipboard power system on real-time capability and effectiveness with relatively simple structure.
