摘　　要：随着现代舰船电力系统容量及电网结构复杂程度的不断增长,重要用电设备对电能品质和供电连续性的要求也在不断提高。本文运用复杂网络理论对舰船电力网络的脆弱性进行研究。针对舰船电力系统的运行特点及要求,提出舰船电网元件的电力介数指标,实现对舰船电网中关键元件的辨识。算例测试表明,该指标能够准确反映各电网元件在舰船电网中的重要性程度及其对舰船电网脆弱性的影响。Withthegrowthofpowercapacityandcomplexityoflargeshipboardpowersystem, demands on electric quality and power supplying continuity of vital electric loads become more and more strict. The structural vulnerability of shipboard power network is studied based on complex network theory. The indicator adapted for the traits of shipboard power system, which is named electric betweenness of shipboard power network components, is proposed to describe and identify the importance of critical network components. The results of tests on a typical shipboard power networks show that the proposed indicator can accurately identify the importance of each network component and its effect to the structural vulnerability of shipboard power network.
