Fault and Disturbance Data Requirements for Automated Computer Analysis (TP 107)

Fault recording practices have advanced from individual substation recorders to a networlc of remote units which transfer fault data records to a central computer for analysis. The analysis process presently consists of examining waveforms and measuring time intervals between various events within the records. This process is labor intensive and requires considerable knowledge and skill. Manpower limitations may result in the failure to identify items needing correction before large financial losses occur.
If rigorous sets of data were acquired, the analysis process could be automated to present data in more meaningful forms and distinguish between normal and abnormal operations. Abnormal operations may require additional manual analysis but much labor would be saved by not having to examine the detail in all fault records.
