## Power Line Parameters
This section discusses the parameters of a specific power line.
### Line Specifications
- **Length**: 250 km
- **Voltage**: 500 kV
- **Frequency**: 60 Hz
- **Configuration**: Uncompensated
- **Conductors**: Four 954,000 cmil ACSR 54/3 per phase
- **Sending-end Voltage**: Held constant at 1. per-unit of rated voltage
### ABCD Parameters
- **A = D**: \(.950 / .1256^\circ\)
- **B**: \(Z' = 88.59 / 87.62^\circ \, \Omega\)
- **C**: \(1.093 \times 10^{-3} / 90.04^\circ \, \text{S}\)
### Equivalent-π Parameters
- **\(Y'\)**: \(1.121 \times 10^{-3} / 89.98^\circ \, \text{S}\)
These parameters are used to model the behavior and performance of the transmission line in power systems analysis.
