摘　　要： 正确接地故障选线是小电流接地系统长期存在的难题,通常采用的单一故障选线方法只对部分故障信息进行处理,选线的可靠性不高。文中把模糊理论应用于故障选线,智能融合各种故障信息,综合各种故障选线方法,并研制出多台样机挂网运行。现场运行记录表明装置选线准确,能适用于各种复杂故障。 Correct fault line detection for the non-solidly grounded system is a longstanding and hard problem in its operation. Traditional single-phase fault line detection methods using only partial fault information have poor reliability. Fuzzy sets theory is therefore introduced and applied in fault feeder detection to intelligently fuse all kinds of the fault information and integrate all of the fault detection methods. Moreover, several testers have been produced and used in spot fields and the fault records show that these testers run well and truly applicable to all kinds of single faults.
