【摘要】：IEC61850标准的应用推动了继电保护信息可视化程度的提升。从实际需求出发,探讨了在继电保护功能时序可视化中应用规范描述语言(Specification and Description Language,SDL)的可行性。提出了将各功能元件等效为不同状态,将不同元件之间信息交互映射为可扩展有限状态机不同状态的转移,并在此基础上采用SDL对目标系统进行建模。通过消息序列图动态展示各元件动作过程,达到直观展示继电保护功能逻辑时序的目的。最后,在实验室环境下构建了系统,并初步可视化展示了距离保护动作时序。结果表明了该方法的可行性,同时也针对信息模型、软硬件协同等问题进行了分析与讨论。
[Abstract]:The application of IEC61850 standard promotes the visualization of relay protection information. Based on the practical requirements, the feasibility of applying the Specification and Description language in the temporal visualization of relay protection function is discussed. It is proposed that each functional element be equivalent to different states, and the information interaction between different components be mapped to the transition of different states of extensible finite state machine. On the basis of this, the target system is modeled by SDL. The action process of each component is dynamically displayed by message sequence diagram, and the logical sequence of relay protection function can be displayed intuitively. Finally, the system is constructed in the laboratory environment, and the time sequence of distance protection action is visualized. The results show that the method is feasible. At the same time, the information model, hardware and software cooperation and other problems are analyzed and discussed.
