| 中文摘要 | 通过介绍一种新颖的配电网保护方案来阐述集成保护的优越性。这个基于暂态极性方向比较的保护方案以伴随故障出现的暂态电流信号的检测和处理为基础,在配电网的各个变电站安装有专门设计的保护继电器,继电器的暂态检测单元检测故障生成的故障分量电信号,并将暂态极性识别算法应用于叠加故障分量信号上,判断信号的极性。通过对来自连接到变电站的所有线路的信号极性进行比较,可以确定出故障的方向。通过处理来自各变电站的方向信息,判别出实际的故障线路,从而实现电网的集成保护。; This paper presents a novel protection and automation scheme for distribution networks called transient polarity directional comparison scheme. The technique is based on the detection and processing of fault generated transient current signals, in which specially designed protection relays are installed at each substation of a distribution network. The transient detection unit of the relay detects the fault generated super-imposed current signals. The transient polarity identification algorithm is then applied to the super-imposed signals to identify the polarity of the signal detected. The direction of a fault is determined by comparison of the polarity of the signals derived from all the line sections connected to the substation. The actual faulted section is identified by processing the directional information from various substations, with which the integrated protection of power network is realized. |
