局域世界演化模型在贵州输配电网中的应用

Application of local-world evolving network model in power transmissionand distribution network of Guizhou

根据贵州电网潮流图和相关数据绘制出其输配电网各节点连接图,运用小世界网络、无标度网络和局域世界演化网络模型对贵州输配电网络的结构特征进行了分析验证,通过实例将贵州电网潮流图分成4个部分,78个节点,对研究节点i的度ki统计,应用网络分布服从指数分布,BA网络的度分布函数,局域世界演化模型的度分布函数相关数据的计算结果比较,表明贵州输配电网符合局域世界演化模型,具备该模型的特性在输电网络中,应加强对集散节点的监控和保护,有必要对相继故障的发生机理、相继故障的预防和控制作深入的研究,确保电力网络安全稳定地运行。

According to the atlas of tidal current and data of electric network of Guizhou, we portray the connecting graphics of electricity transmission and distribution about each node of electric network.We take the advantage of the small-world networks, scale-free network and local-world evolving network model to analyse and validate the construction characteristic of electricity transmission and distribution network of Guizhou. Through on example the tidal atlas of electric network is divided in to 4 sections and 78 nodes. The comparison of calculation results of related data of scale distribution function of the local world evolving network model shows Guizhou distribution ret work accord with the local-wored evolving model, having the characteristics of the model .Monitoring and protection should be strengthened at the collecting and distributing node. It is necessary of further study the mechanism of failures to ensure the operational securing of the power network.
