【摘要】 本文在理论上揭示了偏差-故障电路可及点电压变化阵方向能量与故障信息阵、偏差干扰阵方向能量间的定量关系,分离出最大方向能量子空间,并提出了该子空间与故障信息子空间的最大接近度概念。技术上,本文给出了定位准确度与当今最精良的非线性最小二乘法相当,而定位速度快300～500倍的多故障定位新方法——广义反投影法。更多还原

【Abstract】 By using singular value decomposition, this paper elaborates the quantitative relation among oriented energies of the measurable voltage-change matrix, fault-information matrix and departure-disturbance matrix in departure-fault circuits, describes separation of the maximal oriented energy subspace, and proposes a maximal closeness criterion. Some novel algorithms, under the name of Generalized Inverse Projection (GIP), are presented to locate k-faults. The location accuracy of the GIP is so high as that of the excellent Nonlinear Least Square estimation (NLS), but testing time required by the GIP is only one over several hundreds of that by the NLS.更多还原
