Tianjin Agricultural University, Tianjin 300384, China） 23-1202/TH This paper conduct the research on the optimal allocation of a limited number of PMU in power system device. A three-stage method will be adopted to study theoptimal allocation of PMU. The method assumes that each bus is installed with PMU initially. The first stage and the second stage of iterative algorithmis are used to remove those less important buses of the PMU configuration,and keep the important position of the buses PMU configuration. The third stage of iterative algorithm makes a further minimize of the first stage and the second stage,and considering the observability of power system,to ensure the optimal configuration of PMU.
