摘　　要：本文在RTDS中搭建了牵引变压器的仿真模型,经仿真系统模拟后,通过GTAO/GTDO卡输出仿真模型得出的电气量,并利用功率放大器将计算得到的电气量传输到保护装置,保护装置根据自身的逻辑判断条件给出对应的信号。实时数字仿真仪(real time digital simulator,RTDS)具备仿真精度高,计算速度快,搭建模型方便,模拟故障不会对设备造成损害等优点,利用RTDS对保护装置进行闭环测试,可实时的模拟保护装置运行状况,因此,可减少保护装置的试验周期。In this paper, the model of traction substation is build based on a series of function of RTDS, the dateis calcu- lated bythe RTDS simulator, then GTAO/GTDO card output voltage and current, and the output of the power amplifier to protection device, a signal corresponding to the action of protection device. Real time digital simulator with high simulation accuracy, the fast calculation, convenient build model, fault simulation with no damage of equipment, can do closedloop test protection to device, and simulate the real situation of field operation, greatly shorten the development cycle of the protection device.
