北京地区10 kV配电网架空线路自环互联式接线研究分析

Research and Analysis on Self-ring Inter-connection Mode for 10 kV Overhead Line of Beijing Distribution Network

针对10 kV架空线路普遍采用的树枝式、单电源单环、双电源单环、三电源单环以及分段多联络等传统网络结构进行了研究分析,阐述了它们存在的共性问题,并在此基础上针对性地提出了自环互联式接线方式,从方式灵活性、供电可靠性、异常方式影响以及负载率等方面论证了此种接线方式的优势,为北京地区10 kV架空线路规划与改造提供了一种较为科学的参考方案。

The traditional network structures such as single power branch,single-supply single ring,double-supply single ring,three-supply single ring and multi-segment with multi-contact and so on adopted widely in 10 kV overhead lines are analyzed,and the common problems are explained. On this basis,self-ring inter-connection mode is proposed accordingly. The advantages of this kind of connection mode are demonstrated from the flexibility,power supply reliability,influence of abnormal mode,load rate and so on,which provides a more scientific reference scheme for the planning and reform of 10 kV overhead lines in Beijing.
