本文提出了一个系统的程序，通过该程序可以优化升级测量系统。所建议的过程产生的测量配置可以承受任何单个分支中断或单个测量的丢失，而不会失去网络的可观察性。它是一种基于测量雅可比矩阵和稀疏三角分解的数值方法，使其易于在现有的状态估计器中实现。它可以离线用于规划和仪表放置研究，也可以作为在线可观察性分析功能的一部分实现。通过数值算例给出了具体的过程。
This paper presents a systematic procedure by which measurement systems can be optimally upgraded. The proposed procedure yields a measurement configuration that can withstand any single branch outage or loss of single measurement, without losing network observability. It is a numerical method based on the measurement Jacobian and sparse triangular factorization, making its implementation easy in existing state estimators. It can be used offline in planning and meter placement studies or it can be implemented as part of the online observability analysis function. Details of the procedure are presented using numerical examples.
