基于IEC61850的数字保护装置建模 摘 要 IEC 61850是由IEC TC57负责制定的关于变电站自动化的国际标准。它IEC 61850标准应用于变压器本文介绍了IEC 61850的研究背景、国内外现状、意义及内容，详细阐IEC 61850标准的建模过程IEC 61850功能自由分布和分配的概念，提出了具体在此基础上，以变压器差动速断保护为例，给出了逻辑设备、逻辑节点Modeling of Digital Protective Device According to IEC61850 Abstract IEC 61850 is an international standard about substation constituted by the substation IEC TC57.It reflects the developments direction and automation tendency of automation, and arouses the widespread interest of the domestic and foreign power industry. The transformer is a core equipment in the substation its protection, measurement and control equipments are the main equipments of substation automation system. Therefore，it is significant for us to apply the IEC 61850 standard to the Digital transformers protection, measurement and control. The background, the domestic and foreign present situations, the significance and the content of IEC 61850 are introduced in this paper, the analysis of IEC 61850 standard’s modeling process are described. Firstly, based on the function free distribution and the assignment concept of IEC 61850, the protection, measurement and the control unit are separated and the respective function is describe by the logical node. Secondly, according to the modeling approach and principle based on IEC 61850，the typical protection, measurement and the control logical nodes are taken as examples to complete modeling of logical nodes with UML. At last, the flow chart of the function realization is described and the flow of the function realization is discussed. In this foundation, the transformer differential protection IED is taken as an example to show the configuration process of its logical equipment and the logical node.
