摘要
牵引变电所接地网对电气化铁路安全运营具有重要意义,本文基于CDEGS软件建立电气化铁路牵引供电系统仿真模型,结合模糊判据分析和贴近度计算提出了接地网故障诊断算法及故障点定位方法,并验证了该算法的正确性,为牵引变电所内接地状态在线评估提供了参考。
The earthing network for traction substation has great significance to the safety operation of electrified railway, the paper establishes the simulation model for electrified railway on the basis of CDEGS software, puts forward the calculation methods for earthing network faults and methods for fault location with connection fussy judgment analysis and proximity calculation, and the correctness of the calculation is verified, providing references for online assessment of earthing status inside the traction substation.
