Advanced Universal Grid Analyzer Development and Implementation

This paper discusses the development and implementation of universal grid analyzers (UGAs) with advanced feature such as, a high reporting rate, utilizing the IEEE C37.118.2011 communication protocol, and data compression technology. UGAs are distributional level, real-time, highly accurate, and GPS synchronized phasor measurement units (PMUs). More importantly, UGAs can also be treated as power quality analyzer which monitor the power quality factors such as voltage sag, swell, harmonics measurement, and signal to noise ratio. With the recently issued PMU standard IEEE P60255-118-1, the UGAs are modified and improved with higher reporting rate (Up to 180 frame per second), utilizing IEEE C37.118.2011 protocol, and data compression technology. Finally, a real world deployed UGA in Atlanta is taken as an example to verify the data accuracy and power quality of UGAs.
