目前110 k V及以上电压等级智能变电站的二次系统故障诊断主要依靠测试仪进行离线分析,难以达到实际运行系统中进行在线检测的效果。提出一种新型智能终端,可以根据Comtrade格式的录波自动触发进行多间隔IEC 61850通用面向对象变电站事件(GOOSE)及采样值(SV)的同步输出,使运维人员能在实际运行系统中进行在线故障分析。阐述了新型智能终端的硬件结构,IEC 61850和Comtrade格式的配置映射以及SV和GOOSE的同步输出功能的设计。
At present, the secondary system fault diagnosis of 110 kV and above voltage substations mainly rely on the tester for off-line analysis, which makes it difficult to achieve the online detection in the actual operation system. This paper presents a new type of intelligent terminal that can automatically trigger the multi-interval IEC 61850 GOOSE and sample output (SV) according to the recorded wave of Comtrade format so that the operation and maintenance personnel can carry out the operation in the actual system Online fault analysis. The hardware structure of the new intelligent terminal, the configuration mapping of IEC 61850 and Comtrade format, and the synchronization output function of SV and GOOSE are described.
