摘　　要：首先介绍了基于PMU的系统线性量测模型和可观测性分析,接着分别介绍了5种基于系统完全可观测下的PMU优化配置算法。利用这些算法对几种IEEE标准节点系统进行PMU优化配置仿真研究。结果表明,这几种算法在解的收敛速度、解的收敛性和解的多样性方面各有其特点。因此,所提PMU优化配置方法和算法性能比较具有一定的实用性。The linear model based on PMU and complete observability in power system is introduced, and five methods for positioning PMU with the aim of complete observability are discussed. These methods are applied to several IEEE test systems. From the simulation results, some features of these algorithms are obtained in the computing speed, the astringency and diversity of solution. These methods and their comparison for optimizing PMU placement are proved to be practical.
