铁路10 kV自闭及贯通线故障定位与隔离装置的研制

摘要

根据现有铁路电力远动信息资源，以TI公司的TMS320F2812型号的DSP为硬件平台开发了故障定位与隔离装置。装置通过以太网进行通信，与车站FTU间进行通信连接的电力远动104规约，装置与I/O模块间通信的Modbus TCP规约，装置通过I/O模块采集供电段两端出线断路器的开关遥信量来确定供电方向，完成故障定位与隔离。现场试验运行结果验证了装置的稳定性与可靠性。%Based on the existing railway power telecontrol terminals resources, a fault location and isolation device is developed with the DSP of Type TMS320F2812 made by TI Company as the hardware platform. The communication con-nection protocol between the device and station FTU is via telecontrol 104 protocol,and Modbus TCP protocol is used as communication link between the device and I/O module. With the I/O module collecting the switching values on the outgoing circuit breakers at the two terminals the device can determines the direction of power supply and realize the fault location and isolation. The field test and operation results have verified stability and reliability of the device.
