| 摘要: |
| 当前双通信电源系统已经在国家电网公司各中心站和各电压等级变电站通信机房得到广泛应用，但部分负载仍处于单路供电状态。为避免供电负载掉电而引起业务中断，进一步提高双通信电源系统的可靠性，对传统双通信电源系统及其存在的问题进行分析。并在此基础上，以嵌入监测保护为手段，以控制逻辑为目的，提出一种双通信电源系统自动母联开关的设计方案。该方案实现了负载掉电情况下双电源系统的无缝切换。最终，通过仿真实验表明，该自动母联开关运作稳定，应对故障瞬时作出反应且灵敏可靠，能更好满足现实需求。 |

| Abstract: |
| Currently, dual communication power supply system has been widely used in different central stations and communication rooms of substations with different voltage levels in State Grid Corporation of China, but some of the loads are still in the single-channel power supply state. In order to avoid power service interruption caused by power cut of power supply load, the reliability of the dual-communication power supply system is further improved, and the traditional dual-communication power supply system and its existing problems are analyzed. On this basis, this paper designs an automatic bus coupler switch for dual communication power supply system, which takes the automatic bus coupler switch as the idea, the embedded monitoring protection as a means, and the control logic as a goal. In the case of power failure, the dual power supply system can switch seamlessly. Finally, simulation experiments show that the automatic bus-link switch operates stably, responds to faults instantaneously, sensitively and reliably, and can better meet actual needs.
