智能变电站二次系统施工图设计表达方法

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。

A Construction-drawing Design Expression Method of Secondary System for Smart Substation

Proceeding from the hardware structure and software configuration of smart substation design, the function distribution and structure characteristics of the secondary system are analyzed. The implementation process and software configuration of an information model of the IEC 61850 standard are investigated. In light of the demand for design expression method of the secondary system, a simultaneous design method based on standardized virtual terminals and virtual secondary circuits is proposed. Based on the virtual terminals and traditional secondary circuits, the design drawings and the data model configuration for the IEC 61850 standard are integrated, and the logic connections implicit in the information model are expressed in the form of visual working drawings. Network connection charts, sampling value (SV)/generic object-oriented substation event (GOOSE) information flow charts and virtual secondary circuit charts are employed to fully reflect the information connections of devices. The design expression is conducive to a clear understanding and mastery of the mutual information of the smart equipment by construction and debugging personnel, and will improve the operation efficiency on the spot.
