地铁SCADA智能通信接口装置电源的改进及应用

地铁电力监控系统(SCADA)中大量存在主控制柜之外单独安装智能通信接口装置的情况,该装置往往就地获得电源。在地铁400 V系统分段切换瞬间,会造成该装置意外掉电,装置重启影响数据采集。阐述接口装置电源内嵌超级电容的改进思路,分析与传统的外围解决方案的区别,根据成都地铁建设实践,评价内嵌超级电容改进方案。

Improvement and Application of Power for Intelligent Communication Interface Device of SCADA

Due to metro supervisory control and data acquisition （SCADA） system has a large number of separately installed intelligent communication interface devices outside the main control cabinets, the devices often have to have local power sources. With instant of inter-section switching in metro 400 V system, it will cause accidental power black-out, and the device restart has impact on data collection. It explains the improvement ideas of interface device with embedded super capacitor, and analysis on difference between new and traditional solutions. Based on Chengdu metro construction practice, it evaluates the embedded super capacitor scheme.
