摘要
为了确定智能变电站的正常运行,对智能变电站合并单元异常情况进行分析,阐述了合并单元的工作原理及合并单元双A/D采样不一致、采样无效、断链处理3种异常情况及处理措施,针对某110kV变电站合并单元重启、丢点等异常现场叙述了其处理步骤,为合并单元的异常情况分析奠定了理论基础。
In order to determine the normal operation of intelligent substation,the abnormal situation of the merged unit in the intelligent substation is analyzed.The working principle of the merging unit and the inconsistency of the double A/D sampling of the merging unit,the invalid sampling and the broken chain processing and the treatment measures are described.The processing steps are described for the abnormal scenes such as restarting and dropping points of a 110kV substation,which lays a theoretical foundation for the analysis of the abnormal situation of the merging unit.
