摘要
牵引馈线短路类型包括瞬时性故障和永久性故障两类,区分瞬时性故障和永久性故障是实现牵引馈线自适应重合闸的关键。该文阐述了在Matlab软件平台上构建牵引供电系统模型的步骤与方法,并进行了实例计算。仿真结果表明,短路后的故障电压波形可以作为区分短路故障类型的判据。
The types of the short circuit faults of the tractive feeder includes the transient and permanent faults. The division of the transient faults from the permanent faults is the sticking point of the realization of the adaptive auto-reclosure of the tractive feeder. This paper expounds the process and means to construct the model of the tractive power system with employing MATLAB software and carrys through the calculation with an instance. The simulation results show that the voltage waveform of the short circuit faults could be the criterion of the division of the types of the short circuit faults.
