【摘要】：从智能变电站二次系统的硬件结构和软件配置入手,分析了二次系统的功能分布及结构特点,研究了IEC 61850信息模型组成及软件配置的实现过程,针对二次系统设计表达的需求,提出了基于标准化虚端子的虚拟二次回路图表协同设计方法。以标准化虚端子和传统二次回路为基础,将设计图纸与IEC 61850数据模型配置结合,将隐含在信息模型中的逻辑回路以可视化图纸的形式表达出来,同时,采用网络联系图、采样值(SV)/通用面向对象变电站事件(GOOSE)信息流图、虚拟二次回路图表完整反映了各装置之间的信息连接。该设计表达有助于施工调试的运行维护人员清晰理解和掌握智能设备之间的交互信息,提高现场工作效率。
[Abstract]:Starting with the hardware structure and software configuration of the secondary system in intelligent substation, the function distribution and structural characteristics of the secondary system are analyzed, and the composition of the IEC 61850 information model and the realization process of the software configuration are studied. Aiming at the demand of the design expression of the secondary system, a collaborative design method of the virtual secondary circuit diagram based on the standardized virtual terminal is proposed, which is based on the standardized virtual terminal and the traditional secondary loop. Combining the design drawing with the IEC 61850 data model configuration, the logic loop hidden in the information model is expressed in the form of visual drawing. At the same time, the network connection diagram is adopted. Sample value / general object oriented substation event / Goose) information flow diagram. The virtual secondary circuit diagram completely reflects the information connection between the devices. This design expression is helpful for the operation and maintenance personnel of construction debugging to clearly understand and grasp the interactive information between the intelligent devices. Improve the efficiency of field work.
