摘要
针对电网进行全景建模需求不断增长的问题,对多个电力自动化专业系统和数据集成技术展开研究,提出一种创建电网全景模型的解决方案。通过电力自动化专业系统提供的模型描述规范语言(common information model,CIM/E)文件中获取子模型数据,利用数据提取、转换和加载(extraction-transformation-loading,ETL)技术将子模型数据抽取、转换并集成到统一的电网全景模型中,解决了直接访问各应用系统数据库会暴露数据库设计及对数据库性能产生影响的问题。
Aiming at problem of increasing requirement for plenoptic modeling of power grid, this paper studies multiple power system automatic professional systems and data integration technology and proposes solution to construct panoramic model for power grid. By common information model file provided by power system automatic professional system, it is able to acquire model data and by using extraction-transformation-loading technology, it is feasible to extract, transform and in- tegrate model data into the unified panoramic model which is able to solve problems of database design and impact on database performance caused for reason of direct visit on various application system database.
