配电故障线路快速定位系统的研究开发

Research and development of a rapid location system for distribution fault lines

我国现有的配电线路经常会发生单相短路故障现象,给用户生活带来极大困扰,为尽快防止故障范围继续扩散,便于工作人员快速定位故障并及时修复,当前需要智能化系统提高故障识别效率。以城市配电为例,目前故障定位处理采取的方式是通过人工拉闸停机操作完成故障选线,这样识别故障效率并不高,基于此对新型配电故障线路快速定位进行了分析探索,对实际生产具有一定指导意义。

Single phase short circuit faults often occur in existing distribution lines in China,causing great inconvenience to users’lives.In order to prevent the spread of the fault range as soon as possible,facilitate staff to quickly locate faults and repair them in a timely manner,intelligent systems are currently needed to improve the efficiency of fault identification.Taking urban power distribution as an example,the current method of fault location and handling is to manually pull the switch and stop the operation to complete fault line selection,which is not efficient.Based on this,the rapid location of new distribution fault lines is analyzed and explored,which has certain guiding value for actual production.
