Substation data integration and utilization

Substation intelligent electronic devices (IEDs) generate huge amount of data that may be utilized and integrated automatically. Data recorded by IEDs may be used by analysis applications in attempt to describe disturbance and device action in detail. After collection data may be stored in the substation or another database at a different enterprise location. Those data may be merged in real time with data from another data sources, such as remote terminal units (RTU), to active full substation data utilization. Besides the issue of designing an analysis application there are issues of handling different data formats, database, and interfaces. This paper discusses the research solutions for those issues followed by an implementation example.
