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.
