电网嵌入式故障信息子站的设计与应用

Design and Application of Embedded Fault Information Substation

故障信息子站能够收集保护装置、安全自动装置的动作信号、异常告警信号及波形数据等,并可实现信息远传,可以为调度部门及时地掌握电网故障和保护动作情况,提供详实的信息支持。对一种基于ucLinux操作系统和ARM硬件平台的嵌入式子站设计方案进行分析和讨论,所提出的设计方案有效可行,并且装置在现场得到实际运用,运行效果良好。

The fault information substation can collect action information, exception signal, waveforms of station protection device and automatic security device, and can achieve them distance, may provide the detailed information support for the dispatch department, to grasp the electrical network fault and the protection movement situation promptly. This article has introduced a system based on uclinux and arm stand design of hardware platforms, the proposed design solutions effective and feasible, at the fields for practical use, the movement effect is good.
