PMUmate

Advanced Off-Line Multi-Channel PMU Signal Analysis

  • Mode-Shape Analysis Across Channels - Extract truly multi-channel mode shapes under ambient condition from synchronized PMU data to uncover system-wide dynamic behavior.

  • Automatic System & Mode Order Detection - Leverage intelligent algorithms to estimate system order and identify dominant modes—no manual tuning required.

  • Advanced Filtering and Oscillation Source Location - Apply advanced preprocessing to isolate true oscillatory contents, and locate oscillation sources.
