网络分裂故障定位法中的元件容差研究

A Study on Element Tolerances in Network Decomposition Approachfor Fault Location

研究网络分裂故障定位法中的元件容差问题．用概率方法导出节点容差电流限和节点容差电流增量限，修改了网络分裂故障定位法中的节点测试条件．通过上机仿真实验验证了修改后测试条件的正确性．

The problem of element tolerances in the network decomposition approach for fault location is investigated. Based on probability theory, the limits of node tolerance currents and their increments are derived out and the node testing condition in network decompostion approach for fault location is modified. The testing condition modified was verified by the results of computer simulation.
