The document discusses analyzing SCADA data from India's Southern Regional Grid to better understand relationships between system parameters. It collected data over a year on voltage, generation, reactive power, and frequency at high sampling rate. Studies identified correlations like total demand varying with average voltage and reactive power. However, data quality issues like outliers and inaccurate timestamps posed challenges for analysis. Properly designed data archiving considering future analysis could help utilities better leverage their data.
