Distortion of fault monitoring information is an important factor that affects the accuracy of faulted line section location in low‐voltage active distribution networks (ADNs). This paper proposes a faulted line section location method that considers the layered solution for monitoring information distortion, to improve the accuracy and efficiency of fault location in low‐voltage ADNs. A multi‐target fault section location optimization model that considers information distortion, multipoint faults, and multiple information distortion types is formulated. A combination of information distortion factors is introduced to represent various types of information distortion and to transform the original optimization model into an unconstrained 0‐1 programming problem. A hierarchical fault location algorithm for segmenting the distribution network is designed to solve the low accuracy and efficiency of direct solutions for fault location models resulting from a large number of active distribution line sections. Simulation results show that the fault location method considering information distortion effectively guarantees the accuracy and solution efficiency of faulted line section location of low‐voltage ADN.

考虑信息失真的低压有源配电网分层故障线段定位方法
故障监视信息的失真是影响低压有源配电网（ADN）中故障线段位置准确性的重要因素。提出了一种故障线路断面定位方法，该方法考虑了分层监测信息失真的解决方案，以提高低压ADN中故障定位的准确性和效率。建立了考虑信息失真，多点故障和多种信息失真类型的多目标断层定位优化模型。引入了信息失真因子的组合来表示各种类型的信息失真，并将原始优化模型转换为无约束的0-1规划问题。设计用于对配电网进行分段的分层故障定位算法，以解决由于大量活动配电线路部分而导致的故障定位模型直接解决方案的准确性和效率低下的问题。仿真结果表明，考虑信息失真的故障定位方法有效地保证了低压ADN故障线段定位的准确性和求解效率。
