2) fault distinguishing
故障判别
1.
An artificial neural network for fault distinguishing by sampling halve is presented,and the pretreatment data are amplified.
介绍了一种基于二等分取样,并将预处理数据放大的故障判别神经网络。
3) Judging fault
判别故障
5) fault judgement ratio
故障判别率
6) fault section
故障区段
1.
As the distribution lines are found faulty,the fault section must be located between two breakers.
馈电线路发生故障时,故障区段必然位于两个相邻负荷开关之间的线路上,通过馈线终端单元采集故障信息上报SCADA系统,得到负荷开关上馈线终端的有关故障信息序列,利用故障信息进行故障区段定位。
2.
In this paper, one kind of new fault locating method based on the fault component combining with fault section locating method are presented by summarizing all kinds of fault locating methods in exist, and using TWACS to detect fault of distribution lines before.
本文通过总结现有的各种故障定位方法,利用双向工频通信技术检测配电网故障,提出了故障区段定位法和基于故障分量的阻抗法相结合的双端故障定位方法,来确定故障点。
3.
The second one is based on the wide-area measurement technology,and the current protection at the exit of the first line is combined with the direction information detected by the directional elements at the terminations of the lines to exactly distinguish the fault section,ensure the upper protection\'s selectivity and rapidity.
提出了2种含DG配电网的馈线保护新方案:一种方案是在现有方向电流保护的基础上,将DG上游每条馈线保护的Ⅰ段与其下一级馈线保护的Ⅰ段构成一个通信单元,依据新的整定原则及两级保护动作结果的综合判断将故障快速地隔离在最小范围内;另一种方案是利用广域网将每条线路末端方向元件检测到的功率方向信息和DG上游第1条出线上装设的电流保护的区段判别结果结合起来,精确地区分故障区段,保证上游保护的选择性和快速性。
