| 摘 要： | 在研究了测试点电压增量向量在由支路转移阻抗矩阵组成的空间的正交投影的特性后 ,提出了仅一次测试的结果就可定位故障支路的方法 .该方法将大量的计算工作量转移到测试前进行 ,而测试后的计算工作量较少 ,因此可实现适时在线诊断 .

| Abstract: | Based on the studies of characteristics of orthogonal projection for test voltage vector in branch space which consists of branch transfer impedance,the method of locating fault branch by only one test is advanced in this paper. With this method, a great amount of work can be accomplished before the test and less work is needed after the test. This method can be applied to realize timely on-line fault diagnosis. |

| Keywords: | branch space orthogonal projection tolerance on-line diagnosis |
