摘要
舰船电力系统是一种典型的节点紧凑型独立电力系统,其系统容量相对有限,系统元件种类繁杂,电网运行结构灵活多变,电力节点及线路极易遭受战斗损伤。针对舰船电力系统的结构及运行特点,基于复杂网络理论对舰船电网的脆弱性开展研究,建立了舰船电网等效拓扑模型并提出了电力介数指标,实现了对舰船电网中关键元件的辨识。通过对典型舰船电网进行攻击测试,验证了所提出指标的准确性和有效性。
Shipboard power network is a typical nodes-compact and isolated power system, with limited capacity, multitudes of elements, flexible operating structures and fragile elements. In this paper, research on structual vulnerability of shipboard electric grid is conducted and methods of equivalent topology modeling and reognizing of critical electric nodes and lines in shipboard electric grid are proposed, based on complex network theory and structrual and operating traits and requirements of shipboard power system. With attacking tests on an arranged typical shipboard electric grid, the result shows the validity and precision of the indicator proposed.
