摘要
现阶段,小电流接地系统在我国中压电网中有着较为广泛的应用,然而在各种复杂影响因素的干扰下,单相接地故障选线问题的出现依旧层出不穷且屡禁不止,对设备、线路以及电网的使用安全性、可靠性以及稳定性造成了极大的威胁。基于此,结合国内外小电流接地系统单相接地选线方法的研究现状,并从一定的角度对多种选线方法的特征、优缺点以及应用状况展开探讨,提高小电流接地系统单相接地选线方法的准确性。
At the present stage,the small current ground system is widely applied in medium voltage power grid of China,however under the interference of various complex factors,single phase grounding fault line selection is still emerging and repeated,caused great threat on the equipment,lines and grid use safety, reliability and stability. Based on this,this paper will combine the research status of domestic and foreign small current ground system single-phase grounding fault line selection method,and from the angle of many kinds of line selection method of characteristics, advantages and disadvantages and application status of launches the discussion, aiming to improve small current grounding system single-phase grounding fault line selection method of the accuracy.
