| 摘要: |
| 结合监测点可观测域原理和电压暂降扰动源定位法，构建扰动源可观性矩阵，在此基础上以监测点数最少为目标，以全网电压暂降及其扰动源可观为约束条件，建立监测点最优配置模型，并用0-1整数线性规划方法进行求解。IEEE 30节点测试系统的仿真结果表明，所提方法正确有效，所需监测点数量少，克服了传统监测点配置方法中电压阈值选取困难的问题，且所得电压暂降特征更精确。 |

| Abstract: |
| Based on the observable area principle of monitoring points and the locating method of voltage-sag disturbance-sources，a disturbance-source observability matrix is built and an optimal allocation model of monitor stations is established，which takes the least monitoring points as its objective and the observability of grid voltage sag and corresponding disturbance source as its constraint. The 0-1 integer linear programming method is adopted to solve the model. Simulative results of IEEE 30-bus test system show that，the proposed method is correct and effective，which，with less monitoring points，avoids the difficulty of voltage threshold selection and obtains more accurate characteristics of voltage sags. |
