基于ETL技术的电网运行全景建模

ETL Technology Based Panoramic Modeling of Power Grid Operation

在南方电网开展的一体化电网运行智能系统研究和建设中,针对电力二次系统数据的多样性和孤立性现状,提出了利用ETL技术处理信息共享的方案。该方案将多系统模型数据抽取、转换并集成到统一的电网全景模型中为多系统所共用,其正确性和有效性在实践中得到了验证。

While the integrated operation smart system in China Southern Power Grid （CSG） is studied and developed, aiming at the present situation of the secondary system data in CSG, especially their diversity and isolated status, this paper proposes a ETL based scheme of information sharing, which makes data extraction from the multiple system models, transfi）rmation and integration to a unified panramic model for information sharing, and its correctness and effectiveness have been tested and verified in practice.
