Review of existing infrastructure sytems, administrative processes, and data validation schemes, methods and algorithms

This report presents the results of Phase 1, Task 1 of the Synchro-Phasor Data Conditioning and Validation Project. The task required a “Review of existing infrastructure systems, administrative processes, and data validation schemes, methods and algorithms.” Electric Power Group, LLC (EPG) carried out this task by (1) conducting interviews with utilities; (2) reviewing literature describing synchrophasor systems; and, (3) drawing upon EPG experience with these systems. The intent was to interview all utility recipients of Smart Grid Investment Grant (SGIG) projects, many of their coordinating partners, and other utilities with synchrophasor systems. EPG prepared a survey form that covered all aspects of phasor measurement systems, from planning to O&M. EPG completed 20 surveys, 17 by interview and 3 that were filled in by a utility. Several of the SGIG grant recipients did not participate, even though they were invited to do so. The responses from the 20 surveys formed consistent patterns, so were sufficient for this report.
