An Emulation Environment for Prototyping PMU Data Errors
Idehen, I., Mao, Z., Overbye, T.
Abstract
High quality synchrophasor data ensure that mission-critical applications produce trustworthy results during grid monitoring. Hence, there is a need for risk assessment activities to screen incoming data for errors, and decide if erroneous portions of data be either rejected or passed on to the dependent-applications. Visualization of prototyped PMU data errors provides a means for better identifying and understanding error mechanisms in real-life PMU data. The objective of this work is to develop a framework for the simulation of prototype PMU data errors within an emulation environment. In this work, two errors have been simulated: error due to a time skew, and error due to mislabeled flag bits during a leap second transition..
