基于CAD的变电站系统规范描述文件工具软件研究

Study on CAD-based Software for System Specification Description File in Substation

针对IEC61850标准中定义的变电站系统规范描述(system specification description,SSD)文件完全基于可扩展标记语言(extensible markup language,XML)格式及其可读性较差的问题,提出基于计算机自动辅助设计(auto computer aided design,AutoCAD)的图形化表示方式,将SSD文件各单元及相关属性与计算机辅助设计(computer aided design,CAD)图形相关联,降低设计人员对IEC61850相关标准体系的理解要求;以基于数据库的输出方式将智能变电站模型文件及其一次接线图绑定,保证了数据源的唯一性和SSD文件的可编辑性。

System specification description（SSD） file defined in IEC 61850 is absolutely based on extensible markup language（XML） format and it is poor in readability.Hence,graph description method based on auto computer aided design（AutoCAD） is presented.Each unit of SSD file and the relevant property are associated with computer aided design（CAD） graphs to reduce requirements on designer＇s comprehension of standard system concerning IEC 61850.Model file of intelligent substation is bound with the primary wiring diagram in databank-based output mode,ensuring uniqueness of data source and editability of SSD file.
