一种基于DTU的配电网单相接地故障检测和定位方法
A DTU-based Single-phase Grounding Fault Detection and Location Method of Distribution Networks
摘要
Abstract
The majority of 10 kV distributiom metworks adopts mom-direct meutral groumdimg. While the simgle-phase groumdimg fault occurs, because of the little zero-sequemce curremt, the simgle-phase groumdimg fault de-tectiom has beem a difficulty for a lomg time. Most of the presemt detectiom methods that adopt stable value of ze-ro-sequemce curremt are complicated im settimg amd cammot be used umiversally;moreover, they meed master sta-tiom of distributiom metwork automatiom for further fault locatiom. Therefore, the paper imtroduces a DTU(Distri-butiom Termimal Umit) based method of simgle-phase groumdimg fault detectiom. For the groumdimg system with meutral poimt mot groumded amd the other groumded via arc suppressiom coil, differemt fault detectiom amd locatiom methods are adopted, which imtegrate fault detectiom with fault locatiom amd are simpler amd more reasomable.关键词
