摘　　要：为有效校核电网实时断面的线路参数和高精度监控设备的实际状态,研究基于电网实时断面的线路参数循环校核方法。采用基于插点法的电网实时断面搜索算法,识别电网关键断面;针对所识别电网关键断面,使用基于随机矩阵理论的断面线路参数循环校核方法,实现电网实时断面的线路参数循环校核。在MATLAB 2013b仿真软件测试下,所提方法被证实可有效校核IEEE 118节点系统上电网实时断面的线路参数,校核后参数与实际值一致,可为电力系统电网故障研究提供理论参考。In order to effectively check the line parameters of the real-time section of the power grid and monitor the actual state of the equipment with high precision,the method of cyclically checking the line parameters based on the real-time section of the power grid was studied.The grid real-time section search algorithm based on the interpolation point method was used to identify the key sections of the power grid;aiming at the identified key sections of the power grid,the cross-section line parameter cyclic check method based on the random matrix theory was adopted to realize the line parameter cyclic check of the real-time section of the power grid.Tested in the MATLAB 2013b simulation software,the proposed method was proved to be effective in verifying the line parameters of the real-time section of the power grid on the IEEE 118-bus system.After the verification,the parameters are consistent with the actual values,which can provide a theoretical reference for the study of power system grid faults.
