在已有的PMU优化配置整数线性规划公式的基础上，提出了一种适用于冗余PMU配置、完全可观测和不完全可观测情形的广义整数线性规划公式。由于PUM单元提供精确的电压相量测量和电流相量测量，因此通过PMU测量的集成将提高状态估计的准确性、冗余性和鲁棒性。由于不同的目的和考虑，需要研究PMU的最优配置问题，即冗余PMU的配置问题、完全可观测性问题和不完全可观测性问题。作者在另一篇论文中提出的建模方法，将PMU配置问题建模为整数线性规划问题，本文对该方法进行了扩展和推广，以满足不同的需要。被认为是与零注入测量和没有的情况下。对不同电力系统的仿真结果表明，该算法具有一定的实用价值。
Based on the integer linear programming formulation proposed for optimal PMU placement, this paper presents a generalized integer linear programming formulation for cases including redundant PMU placement, full observability and incomplete observability. Due to accurate voltage phasor measurement and current phasor measurements provided by PUM units, the accuracy, redundancy and thus the robustness of state estimation will be enhanced with the integration of PMU measurements. The problem of optimal placement of PMU for the redundant PMU placement, full observability and incomplete observability analysis needs to be studied, for various purposes and considerations. The proposed modeling approach by the author in another paper, which models PMU placement as an integer linear programming problem, is extended and generalized to satisfy different needs. Cases with and without zero injection measurements are considered. Simulation results on different power systems show that the proposed algorithm can be used in practice.
