摘　　要：为了解决使用有效性模型分析变电站自动化系统连锁故障时,不能根据系统变化调整逻辑节点负荷容许参数的问题,基于变电站自动化系统的逻辑连接建立复杂网络,引入接近度概念来衡量逻辑节点在信息传递中的重要性,并动态调整节点负荷容许参数,建立了一种适用于变电站自动化系统连锁故障分析的改进有效性能模型。在此基础上,以T1-1型变电站为例,完成了在不同扰动方案下系统效率损失情况的对比分析。实验结果表明,改进后的模型能够更好地适用于变电站自动化系统连锁故障分析。Permissible tolerance parameters of logical nodes cannot be adjusted according to the state of system when analyzing cascading failures of the substation automatic system（SAS）by using the model of effective properties.To solve this problem,a complex network based on logical connections of SAS is designed.The concept of closeness centrality is proposed to measure the importance of a node in the information transfer,and the permissible tolerance parameters of logical nodes are dynamically adjusted.In this way,an improved model of effective properties for analyzing cascading failure of SAS is developed.On this basis,the system efficiency loss in T1-1substation in different disturbance cases is analyzed.Experimental results show that the improved model is more suitable for analyzing cascading failures of SAS than the previous model.
