| 摘要: |
| 针对基于逻辑关系的馈线故障定位间接方法存在过分依赖群体智能优化算法的固有缺陷，采用代数关系描述，构建了基于故障辅助因子的馈线故障区段定位的非线性方程组模型，并采用具有并行特征的牛顿-拉夫逊法进行求解，其优点在于：对报警信息畸变的情况具有强适应性，故障定位时具有高容错性；能够对含T型耦合节点的配电网多重馈线故障区段进行准确定位；无需采用逻辑运算和最优化算法，决策效率高、算法稳定性好；单一故障下可准确定位信息畸变的位置。仿真结果验证了所提方法进行馈线故障区段定位的准确性、快速性和高容错性。 |

| Abstract: |
| Aiming at the inherent deficiency of the indirect feeder fault locating based on the logical relationships, i. e. the excessive dependence on intelligent optimization algorithms, the algebraic relationship description is applied to establish a nonlinear equation group model based on the fault accessory factors for locating the faulty section of feeder and the Newton-Raphson algorithm with parallel features is adopted to solve the model. The proposed method has strong adaptability to alarm information distortion and high tolerance in fault locating; without logic operation and optimization algorithm, it has high decision efficiency and good algorithm stability; it can accurately locate multiple faulty sections of distribution network with T-type coupling node; in the condition of single fault, it can accurately identify the location of alarm information distortion. Its accuracy, rapidity and high-tolerance are verified by the simulative results. |
