The Archive Sprinter tool is designed to efficiently process synchrophasor measurements from electric power grids and export data signatures that summarize the grid's behavior. Parallel processing will allow data to be processed quickly to enable practical analyses of archives spanning years. The grid's behavior will be summarized using a wide-array of signatures calculated from the input data. These signatures include values such as the mean, variance, maximum, and correlation coefficient. Such signatures will be useful in establishing baseline behavior and identifying deviations from the baseline. Identifying deviations will help researchers and utilities identify grid disturbances that can be further analyzed with related tools developed by PNNL.
