摘　　要：基于电力系统线性量测模型 ,研究了引入相量测量单元 ( PMU)相关量测集后的增广关联矩阵的电力系统可观测性拓扑分析方法 ,以保证系统结构完全可观测性和最大量测数据冗余度为约束 ,以配置 PMU数目最小为目标 ,形成了 PMU最优配置问题 ,并应用禁忌搜索 ( TS)方法求解该问题 ,保证了全局寻优。算例表明 ,该方法准确可靠。A novel topology method of network observability using augmented incidence matrix is studied in this paper based on linear measurement model of power system. The optimal PMU placement problem is formulated as guaranteeing full network observability, maximizing the redundancy measurement and having minimum number of PMU. And TS method is proposed to solve the combinatorial optimization problem. The effectiveness and flexibility of the proposed algorithms are illustrated with numerical simulation using IEEE 39 bus system, IEEE 57 bus system and NE 39 bus system.
