摘　　要：输电网络的安全运行直接关系到国计民生,研究大型城市输电网络演化模型,对于保障城市供电安全更有着显著的意义。本文基于上海地区近五十来年输电网络演变数据的实证研究,结合城市电网的实际演化特点,提出一种灵活的加权复杂网络演化模型算法,通过仿真验证该模型可以较好地反映大型城市输电网络各演化阶段的实际特点,并且进一步证实了上海输电网络既不是无标度网络,也不是完全的随机网络,在节点数达到一定程度时,上海输电网络开始表现出显著的小世界特征。该算法的提出为研究大型城市输电网络特征,分析外力破坏因素导致的停电事故,提供网络模型演化依据。Operating security Transmission network is matters vital to national well-being and social stability, the evolutionary models have great value for further study on transmission network in the major cities, so the researches on it are significant not only in theory but also in application for reliability of power supply for the cities. This paper provides an empirical study based on structural data of evolving network for transmission network in Shanghai in recent fifty years, according to the urban power networks＇ character in the practical evolution, the authors put forward an analytical framework of network evolution. This evolution model is more effective and closer modeling of the characteristics in each evolution stage, which is testified by doing experiment and simulation.The results show that transmission network in Shanghai are not scale-free, and not completely random. This transmission network have small-world phenomena when the number of nodes reached a certain level. Thereby the algorithm will provide one more way in the research of the major cities＇ transmission network characters and the analysis of the whole process of the outage.
