摘要
运用均匀传输线和电路四端网理论,建立了ZPW-2000无绝缘轨道电路分路电流的计算模型,利用MATLAB软件实现了分路电流的数值算法.仿真了轨道电路正常情况、补偿电容开路和短路故障情况下分路电流的分布,仿真数据对轨道电路故障诊断有较大价值.
Based on the theory of uniform transmission line and fourterminal net circuit, this paper presents a simulation model of ZPW - 2000 jointless track circuit shunt current. A kind of numerical algorithm of shunt current is established with MATLAB. Simulation calculation is carried out based on the conditions such as track circuit in normal state, shunt current distribution in open or short circuit failure. The results of simulation are valuable to track circuit fault diagnosis.
