Phasor Measurement Unit (PMU) Synchrophasor Data
This dataset provides high-resolution, time-synchronized phasor measurements from PMUs across the power grid, including voltage/current phasors, frequency, ROCOF, and GPS status. It enables wide-area grid monitoring, event detection, and advanced analytics for grid stability and reliability. The inclusion of location and quality flags makes it ideal for both real-time operations and historical analysis.

Behind this dataset
Same schema. As many rows as you need.
These 250 rows came out of a blueprint — 14 columns with generation rules behind each one. Open it in Data Factory to retune a column, add your own, wire in foreign keys, and run it at the size you actually need.
Rules it was built with
- PMU ID and location (substation, bus)
- GPS time-synchronized timestamps (UTC)
- Reporting rate: 30, 60, or 120 samples per second
- Voltage phasor: magnitude and angle
- Current phasor: magnitude and angle
- Frequency measurement (nominal ±0.5 Hz)
- ROCOF (Rate of Change of Frequency) in Hz/second
- Total Vector Error (TVE) < 1% per IEEE C37.118
