Application-Aware Adaptive Reporting of Synchrophasor Measurements

Phasor Measurement Units (PMUs) are capable of providing high speed and high-resolution wide area measurements typically used for situational awareness and advanced applications. A PMU for distribution systems also known as micro-PMU can provide data even at higher reporting rates. Despite its apparent advantages, reporting at a much higher rate introduces additional communication burden. This constraint will be even more critical with ‘point to wave’ reporting possible in future. Several applications do not require the measurements at that high reporting rate, e.g. state estimation or condition monitoring. Possible congestion in the network with several thousands of these devices may result in either significant delays or packet drops. This work is an efforts towards providing solutions for above challenges with an adaptive PMU, which is capable of adjusting reporting rate based on the communications network bandwidth and/or the application needs.
