Powerflow Database
PFDB is a tool designed for assembling a series of powerflow base cases for a large region from data submitted by its members. The tool is currently being used in the annual effort of developing NERC/ERAG US/Canada Eastern Interconnection (EI) base powerflow cases.
Features
- Extraction and merging of powerflow data by control areas from different powerflow cases
- Settlement of area interchanges and tie-lines in merged case
- Check of powerflow data among whole series for specific model year
- Comparison of powerflow cases
- Check of powerflow cases for data errors according to NERC/ERAG/MMWG requirements, including:
- Duplicate bus names
- Bus, owner, zone out of range
- Bus voltage out of range
- Incorrect generator type code
- Missing generator on generator bus
- Unrealistic PMAX, PMIN, QMAX, and QMIN
- Generator output out of range
- Incorrect generation share
- Generator step-up transformer tap setting out of range
- Shunts with small control voltage bands
- Shunts without block 1 steps
- Inconsistent transformer data
- High resistance branches
- Branch rating errors
- 3-winding transformer rating errors
- Branch overloads
