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。The application of IEC61850 promots relay protection information visualization. The feasibility of employing SDL（Specification and Description Language） into application of relay protection function sequence visualization is discussed from practical demands. Taking each function component as different states is also presented, as well as mapping information exchanging between different components into transition of different states compatible with EFSM（Extended Finite State Machine）. On the basis, this target system is modeled by SDL, the sequence of every component action visualized dynamically through MSC（Message Sequence Chart） is achieved, thus protection function logic is visualized directly. Experiment system is constructed and sequence of distance protection is visualized preliminary. The result also shows that the proposal approach is feasible. In the end, problems such as information model, coordination design of hardware and software, etc. are analyzed and discussed.
