摘要当代社会与经济的快速发展都主要依赖于基础设施系统，主要有电力系统、 供水系统、天然气与石油、通讯等基础设施。在这些基础设施中，电力系统是最 受关注，因为许多其它基础系统都需要稳定的电力系统提供电力来保证它们的管 理和运行。然而，目前我国电力系统面临各地区电网网络互联等因素的影响，增 加了电网的复杂性。对于影响电网的复杂性来源，有些是不可控的，导致了电网 事故的不可避免性。越来越多的学者们开始关注研究电网的复杂特性和如何保障 电网的安全运行。

传统的电力系统分析方法逐渐出现一种局限性，无法准确研究如今的电力系 统。复杂网络理论的提出，给所有分析电力系统脆弱性的学者们提供了一个崭新 的视角，它不仅强化了电力系统与数学、互联网和系统科学等学科之间的关系并 且使得也各个学科的相互融合，为保障未来的电力系统的安全运行和管理做出了 非常大的贡献。为了更好的保护电网，所以本文采用基于复杂网络理论来进行对 电力系统的脆弱性进行探究。并且通过复杂网络理论来描述电力系统的拓扑性结 构，深刻了解电力系统的结构特性和功能特性，同时也给出了电力系统的脆弱性 分析理论框架进行更深层次的研究。选取三种常见的复杂网络模型以及六个常见 的脆弱性指标，通过建立模型对节点攻击，仿真比较得出结论，脆弱性分析的目 的就是为了更好的保护电力系统，从而尽量避免意外事故的发生。72283

Vulnerability analysis of power system based on complex network theory

Abstract

The development of modern society and economy rely heavily on infrastructure systems, including power grid systems, water supply systems and communication systems and so on。 Among these systems, power grid systems are especially important because many other systems rely on power supply for operation and management。 However, our country electric power systems grid network interconnection now, the complexity of the grid on the increased 。Some of the complexity of the power grid is not controllable, which leads to the inevitability of power grid accidents。 The complexity of the large power grid and the safety of the large power grid are being paid more and more attention。

The traditional method of power system analysis the gradual emergence of a limitation, unable to accurately study the power system now。Complex network theory for power system of fragile analysis provides a new research direction, strengthen the power system and mathematics, network and system science disciplines cross fusion, made very large contribution for the safeguard of modern power system safe  and stable operation。In order to better protect the power grid, this paper puts forward the vulnerability analysis of complex network theory in power system based on。Using complex network theory to describe the topology and function of  power system, deeply understand the structure and function of power system, and  also  give the theory framework of vulnerability analysis of power system。 Selected three common complex network models and six common vulnerability , draws the  conclusion through the simulation comparison, the purpose of vulnerability analysis is to better protect the power system, so as to avoid the occurrence of accidents。

The paper has seven figures, thirty-five references。
