Efficient and compact archiving of PMU data

Stability Proactive Grid Management | GE Digital Energy | WAMS

PhasorHistorian provides efficient and compact archiving of PMU data, applications results and summary data. Data repositories within the Historian allow flexible data management and transparent user access to full resolution, down sampled, snapshot and summary data.

 

Short Term Rolling Archive stores full resolution data for a fixed duration or until the archive reaches its maximum size.

 

Long Term Rolling Archive stores the data at a user configurable resolution for a significantly longer duration.

 

Snapshot Archive stores snapshots of data at full resolution. These are generated when a Triggered Storage event occurs or when a user copies a selection of data from the Short Term Rolling Archive to the Snapshot Archive.

 

Summary Archive stores maximum, minimum and average value summary-data for each PMU. Data is retrieved from the data archives in a number of ways
