Abstract

The phasor measurement unit (PMU) is a networked, GPS time-synchronized wide-area-monitoring device for modern power transmission systems. The recent and widespread adoption of these devices will provide a wealth of information about the dynamic state of the power system. However, the increasing number of measurement points and high data reporting rates make real-time human interpretation of large data sets problematic. Thus, this work presents a method for the real-time automated analysis and visualization of time-synchronized phasor measurements for online event detection, location, and system characterization. The method employs cross-correlation and wavelet multi-resolution signal processing techniques for noise removal. Finally, the technique is implemented in Matlab and applied to simulated phasor measurements from an IEEE 14-bus test system implemented in PSCAD/EMTDC, in addition to a real-world phasor measurement data set.
