| 摘 要： | 本文主要介绍了在ATPDraw环境下如何建立2×27．5kV复线AT牵引网的模型，该模型充分考虑了AT漏抗、线路互感、钢轨对地漏导等因素对牵引网阻抗的影响，并使用ATP-EMTP仿真出在以上因素影响下的牵引网故障短路电流波形，同时应用“AT中性点吸上电流比”及复线“上下行电流比”故障测距方法证明了该模型的实用性．

| Abstract: | The paper mainly introduced how to model a 2 × 27.5 kV AT multiwack electric network using ATPDraw. This model fully considered the influence of AT leakage reactance,mutual-inductance between lines and the leakage inductance between railroad rail and ground to the impedance of traction electric network.Based on proposed model,the wave of short-cut current under fault in railway traction electric network is simtdated by ATP-EMTP.The practicability of this model is certified by the fault-location methods of ＂AT neutral current ratios＂ and ＂Up and down currents ratios＂. |
