IEC61850标准下合并单元的信息模型与映射实现

Information Model and Mapping Implementation of Merging Unit Based on IEC61850

合并单元是随着电子式电流、电压互感器的产生而出现的,在一定程度上实现了过程层数据的数字化和共享化。文章首先介绍了IEC61850标准的基本特点和实现的一般方法。在研究IEC61850信息模型内涵的基础上,从分析合并单元的功能入手,研究了合并单元信息模型的属性和抽象通信服务接口,阐述了合并单元信息模型的构建方法。然后讨论、分析了合并单元抽象功能服务的通信映射方法和帧格式。最后简单介绍了用于装置自我描述的SCL(Substation Configuration description Language)配置文件的基本格式。

Along with the application of ECT and EVT the merging units appear, and to certain extent the digitization and sharing of data of the process layer are implemented. Here, firstly the basic features of stand IEC61850 and the general approach to realize this standard are presented; on the basis of researching the intension of IEC61850 information model and starting with the function analysis of merging unit, the attribute of merging unit information model and abstract communication service interface are researched, and the method to construct information model of merging unit is expounded. Then, the communication mapping method for abstract function service of merging unit and the frame format are analyzed. Finally, the basic format of the configuration file for the self-description of devices by Substation Configuration description Language （SCL） is briefly introduced.
