数字化变电站信息流的智能分析与可视化

Intelligent analysis and visualization of information flow in digital substation

数字化变电站技术使用工业以太网技术代替传统二次接线传递数字和模拟信号,使得原有相互解耦、具象的二次接线被相互高度耦合、抽象的网络数据流所替代,给运行、调度、检修等相关专业带来了严峻的挑战。针对该问题,提出了一种数字化变电站信息流智能分析与可视化系统构架,将网络数据流以更为直观的图形方式显示给运行和检修人员。研究结果表明,该系统使得运行维护人员能够迅速、准确地掌握保护系统的运行和动作状况,进而降低了人为误操作的概率,提高了数字化变电站的运行可靠性。

The technology of digital substation replaces the traditional electrical cables with fiber to transfer the analog and switching value. The decoupling and concrete cable is substituted with coupling and abstract information flow,which greatly challenges the running, maintaining and dispatching of the digital substation. To overcome this problem, a brand new architecture of information flow intelligent analyzing and visualizing system in the digital substation was proposed. Basing on the distributed information gathering system,the intelligent analyzing and visualizing system supplies the maintainers and dispatchers with all abstracted and analyzed flow information running in the fiber in the form of direct graph. Results show that the system can decrease the human error on operation and increase the reliability of the digital substation.
