摘　　要：根据复杂网络理论,将大型电力系统用带权网络模型来描述,基于此模型下的节点最短电气距离提出了一种运行方式组合方法。该方法利用节点最短电气距离表征节点间电气联系强弱的特点,给出了故障电流计算和分支系数计算的最短电气距离判据,据此找到系统内对故障电流和分支系数影响大于某一阈值的厂站,将其纳入进行方式组合,以达到优化运行方式组合的目的。Based on the complex network theory,the large-scale power system is described by the weighted network model.According to shortest electrical distance of nodes which belongs to this model,a method for operation mode combination is presented.The method makes use of the feature that shortest electrical distance of nodes represents the degree of their electrical association to find criterions for calculating fault current and branch parameters.And hereby the operation model of substations or plants with great impact on the setting values of relays will be considered,so finally achieve the purpose of optimizing the operation mode combination.
