| Issue | Description | |-------|-------------| | | Different PDFs use different bus numbering, line parameters, or load values (e.g., one common variant has a generator at bus 6, another at bus 2). | | Missing tap ratios | If transformers exist, tap settings are often omitted or unclear. | | No validation | Few PDFs verify if data produces a converged power flow or provide expected results. | | Poor scanning | Older scanned PDFs may have illegible numbers or missing tables. | | Unit confusion | R and X sometimes given in per-unit, sometimes in ohms without specifying base kV. | | No Q limits | Generator reactive limits are frequently absent, making optimal power flow studies difficult. |
The line data provides the parameters of the transmission lines and transformers, including resistance (R), reactance (X), and sometimes line charging susceptance (B) and transformer tap ratios. An example of line data for a 6-bus system is provided below.
