摘　　要：阐述了新一代智能变电站中继电保护故障记录信息流方案,指出了继电保护故障可视化分析的应用方式。分析了电力系统图形描述规范(G语言)表达图形的方法,并对继电保护逻辑图进行了研究和抽象。在此基础上,提出一种应用G语言表达继电保护逻辑图的方法,并进一步提出了继电保护故障可视化分析的整套方案。该方案中,继电保护装置采用G语言对其保护逻辑图进行自描述,后台服务器采用通用的G语言解析工具对继电保护装置的逻辑图形文件进行解析和可视化回放分析。该方案解决了不同厂家设备间的兼容性和互操作性问题,以及保护逻辑图与保护程序不匹配的问题,具有软件处理简单、通用性强、可靠性高、易于实现的优点。The information flow scheme for relay protection fault recording in the new generation of smart substation is described.The application mode of fault visual analysis for relay protection is pointed out.The graphic expression method based on graphical description specifications of power system （G language） is analyzed.Based on the abstraction of relay protection logic diagram,a method is put forward by using G language to express relay protection logic diagram.A whole package of fault visual analysis for relay protection is further proposed,in which the protection logic diagram is self-described with G language,and the logic diagram document is resolved and replayed visually by the common G language analyzing tool on the backend server.The scheme has radically solved not only the compatibility and interoperability problems between different equipment manufacturers,but also the mismatch problem between logic diagram and protection program,demonstrating its advantage of simplicity,versatility,high reliability,and easy implementation.
