摘　　要：为了进一步降低网络负荷重分配(network load redistribution, NLR)攻击对变电站线路停运的影响,设计了一种考虑NLR攻击的变电站可靠性评估流程。分析NLR负荷攻击方案,设置线路潮流相依姿态下实时停运模型,根据最优负荷削减过程来确定系统安全状态,并以IEEE 14节点为例进行算例分析和可靠性评估。结果表明:受到NLR攻击后会形成不同节点负荷分布状态。随着攻击资源数提高,NLR攻击会引起负荷削减。不同NLR攻击场景下,考虑线路停运会增强负荷削减结果可靠性。所提方法提高了变电站运行安全可靠性指标,有助于电力系统信息化建设。In order to further reduce the impact of network load redistribution(NLR)attacks on substation line outages,a substation reliability evaluation process considering NLR attacks was designed.The NLR load attack scheme was analyzed,and the real-time outage model under the line power flow dependent attitude was set up.The system security state was determined according to the optimal load reduction process,and the IEEE 14 node was taken as an example for example analysis and reliability evaluation.The results indicate that the load distribution of different nodes will be formed after being attacked by NLR.As the number of attack resources increases,NLR attacks will cause load reduction.Under different NLR attack scenarios,considering line outage will enhance the reliability of load reduction results.The proposed method improves the safety and reliability indicators of substation operation and contributes to the informatization construction of the power system.
