摘　　要：针对电力系统安全防御中对关键环节辨识的需要,提出电网关键线路序元的概念。综合结构脆弱性指标及网络性能指标,构造线路序元的综合重要度指标,结合多属性决策方法筛选出关键线路序元。针对大规模的线路序元多属性优化排序问题,给出相应的粒子群优化求解方法。以IEEE 39节点系统和河北南网实际系统为例,搜索系统的关键线路序元。仿真结果表明,提出的方法能够有效筛选系统的关键线路序元,可为电网联锁故障的预防提供指导。Aiming at the demand of key link identification in power system security defense, the paper puts forward the concept of grid key line sequence. Based on the structural vulnerability indexes and network performance indicators, this paper constructs the comprehensive importance index of line sequence and selects key line sequence in combination with the multiple attribute decision making method. Regarding multiple attribute optimization and sort of large-scale line sequences, particle swarm optimization algorithm is given. Taken IEEE 39-node system and Hebei southern power gird as examples, the experimental results of searching key line sequences show that the proposed method can effectively filter the system key line sequences and provide guidance for power grid cascading failure prevention.
