Impedance from Per-Unit System Evaluator.
Function to reverse per-unit conversion and return the ohmic value
of an impedance given its per-unit parameters of R and X (as Z).
- Parameters:
- z_pu : complex
The per-unit, complex value corresponding to the
impedance
- S3phs : float
The total three-phase power rating of the system.
- VLL : float, optional
The Line-to-Line Voltage; default=None
- VLN : float, optional
The Line-to-Neutral Voltage; default=None
- Returns:
z – The ohmic impedance evaluated from the per-unit base.
- Return type:
complex
