Scalable Data Compression and Management for Spectral Analysis of Power Grid PMU Data

Project Status: 

The objective of this project was to improve the capability of BPA to manage the enormous amount of data used and generated in various analysis processes including oscillation detection. Working with domain experts in BPA, this project worked to develop data reduction algorithms to reduce the amount of data that OSISoft PI needs to process. Additionally, a data management system was also developed to handle big data.
