摘　　要：为了利用EMTP进行轨道电路的暂态分析,采用相模变换消除轨道电路传输方程中钢轨回路间的耦合,得到模域轨道电路传输方程,利用实际钢轨线路为串联应用的特征,导出轨道电路去耦传输方程,得到轨道电路等效电路图,在EMTP的CP模型中加漏泄电阻的形式,获得了轨道电路EMTP仿真模型.仿真结果表明:所得计算结果与文献[7]一致,证明所建立模型的正确性.In order to realize transient analysis of track circuit with EMTP,the coupling of loop is eliminated by phase-mode transformation of the track circuit transmission equation,then the track circuit transmission equation is got in mode domain.According to the principle that track circuit is in series in practical,the decoupling transmission equation in phase domain is obtained.Based on this equation,the equivalent circuit of track circuit is taken.Lastly,the simulation model of track circuit is established with CP model of EMTP and leaklage resistance.The simulation result is the same as reference[7],which proves that the simulation model is correct.
