| 摘要: |
| 针对智能变电站硬电缆回路被虚拟二次回路代替造成的信息不透明问题，提出了一种可视化的虚拟二次回路监视方案。该方案由过程层及间隔层设备判断虚拟二次回路异常并产生异常信号，利用一体化监控系统的数据传输通道，将虚拟二次回路异常信号以遥信的形式传输到站控层，站控层解析收到的异常信号并展示。在研究IEC 61850的短地址模型的基础上，利用短地址实现了站控层的遥信数据点与过程层及间隔层的虚拟二次回路异常信号之间的映射关系。根据现场使用情况，该方案解决了虚拟二次回路状态监视手段缺乏的问题，方便了问题的查找和定位，对运维人员来说是非常有用的。 |

| Abstract: |
| Aiming at the information opaque problem that caused by hard cable loops are replaced by virtual secondary circuit in smart substation, a solution of visualized circuit monitoring is proposed, which uses the IEDs in process layer and bay layer to determine whether a virtual secondary circuit is abnormal and generating abnormal signals, then the signals are sent to station layer by data transmission channel of the integrated supervision and control systems in the form of telesignalling, finally, the abnormal signals are received and analyzed and displayed by the station layer. Based on the research of IEC61850’s short address model, it establishes the mapping between telesignalling in station layer and virtual secondary circuit abnormal signals in process layer and the bay layer by short address. According to the usage in smart substation, the solution is very helpful to operation and maintenance personnel, it solves the lack of means for monitoring on virtual secondary circuit state, and is convenient to find and locate the problem. |
