Real-time Synchrophasor Data Quality Analysis and Improvement (S-71)

Summary This project aims at developing strategies for real-time data quality management of streaming PMU data. With the recent impetus towards design and adoption of synchrophasor-based applications in the power industry, there is an urgent need to develop online techniques for detecting, analyzing, and mitigating bad as well as missing data in real-time streams. In this project, we will build a systematic online framework for identifying and handling typical data quality issues such as clock errors, transducer errors and network delays. Based on the synchrophasor data¿s spatio-temporal correlations, the proposed approach is capable of identifying bad data during both normal and fault-on conditions. Real-world synchrophasor data as well as synthetic dynamic grid models will be used to differentiate the root causes of data quality issues and to validate the proposed strategies.
