提高牵引供电系统故障测距精度的探讨

Discussion of Improving of Fault Location Accuracy for Traction Power Supply System

针对电气化线路投运初期故障测距精度不高的现状,提出了将接触网按线路长度平均分成3段进行测距计算的方法,减少了线路互感对测距的影响,该方法提高了电气化铁道牵引网故障测距的精度。

This paper contraposes to the status quo of low accuracy of fault ranging in the early time of the electrified railway to the le system in used, for the ranging, advanced a method that dividing the catenary systems into 3 sections according ngth of the line, which improves the accuracy of fault ranging in electrified railway catenary system .
