基于IEC 61850标准的过程层测控终端的设计

摘要

由于数字化变电站系统设计是基于IEC 61850标准，即系统具有较好的开放性、互操作性和扩展性特征，表明变电站系统向自动化的方向发展。该文对数字化变电站IEC 61850进行了详细介绍和分析。针对目前变电站的数字化改造的实际需要，提出了过程层测控终端的软硬件具体设计方案，该方案对于未改造的变电站进行数字化改造来说，在理论和经济方面具有重要的指导意义。%　　IEC61850 based digital substation system (DSS)is highly open, interoperable and extensible, which is the direction of substation automation system (SAS).The introduction of the professional standards-IEC61850 relation to digital substation tech-nology are discussed. For the traditional substation digital reconstruction, the software and hardware detailed design of process moni-toring terminal unit (PMTU)are proposed. The proposed method has important theory significance and engineering value to the con-ventional digitization transformation.
