Traditional COMTRADE Application

• Individual engineers use stand-alone power system analysis tools to transfer and analyze COMTRADE disturbance data from IEDs.

• After analysis and a potential corrective action what happens to the COMTRADE data:– Deleted– Files stored locally and isolated– The underlying power system data is not avialalbe

outside the tool used for analysis

The Role of IEC 61850 in COMTRADE Processing

• Disturbance file presence detection:– IEC 61850 FileDirectory service polling– RDRE – Disturbance Recorder Monitoring

• RDRE.ST.RcdMade (recording made)• RDRE.ST.FltNum (fault number)

Role of CIM in COMTRADE Processing

• The IEC Common Information Model (CIM) is used to define the power system and its assets

• CIM is imported into the historian where COMTRADE is processed

• Enables disturbance data is associated to the assets impacted

• Enables events to be associated to the disturbance file for later retrieval

COMTRADE Utility for PI

• All disturbance files are transferred automatically and archived in the PI historian.

• Disturbance data from COMTRADE files is extracted and store in PI along with all other power system data.

• Using CIM with PI Asset Framework (PI AF) enable related of disturbance files to the asset and an event.

• Data can be exported into COMTRADE file for sharing with others (e.g. synchrophasors).
