Behind this dataset
Same schema. As many rows as you need.
These 100 rows came out of a blueprint — 15 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
- Bus ID or substation node for load location
- ZIP model coefficients: %Z (impedance), %I (current), %P (power)
- Motor load percentage: typically 40-60% of total load
- Electronic load (constant power): computers, LED lighting
- Voltage dependency: load varies with V^2 for Z, V for I, constant for P
- Dynamic load recovery time constants (seconds)
- OLTC (on-load tap changer) and capacitor bank interaction
- Voltage collapse margin analysis and critical voltage thresholds
