论文摘要
本文介绍了一种算法，能够使用相法测量单元（PMU）收集的测量结果，能够检测和定位主动分布网络中故障的发生。首先，在设计所有网格总线配备PMU的假设下起作用的基本算法。然后，提供了允许检测和定位的正式可观察性条件，并提供了减少的PMU。基于这些条件，在监视所有网络总线时，算法将扩展到正确执行。此外，设计了一种始终基于可观察性条件的最佳定位算法。该算法允许用户自定义故障本地化分辨率。该方法通过基准主动分配网络上的模拟进行验证。
This paper introduces an algorithm able to detect and localize the occurrance of a fault in an Active Distribution Network, using the measurements collected by Phasor Measurement Units (PMUs). First, a basic algorithm that works under the assumption that all grid buses are equipped with a PMU is designed. Then, formal observability conditions that allow detection and localization with a reduced number of PMUs are provided. Based on these conditions, the algorithm is extended to perform correctly when not all network buses are monitored. Moreover, an Optimal Positioning Algorithm, always based on the observability conditions, is designed. This algorithm allows the user to customize the fault localization resolution. The approach is validated through simulations carried out on a benchmark active distribution network.
