electricpy.fault.genlossfield(Xd, Xpd, Zbase=1, CTR=1, VTR=1)[source]

Electric Generator Loss of Field Function.

Generates the Loss-of-Field Element settings for a generator using the Xd value and per-unit base information.

Parameters:

  • Xd (float) – The Transient Reactance (Xd) term. May be specified in ohms or Per-Unit ohms if Zbase is set.

  • Xpd (float) – The Sub-Transient Reactance (X’d) term. May be specified in ohms or Per-Unit ohms if Zbase is set.

  • Zbase (float, optional) – Base impedance, used to convert per-unit Xd and Xpd to secondary values. default=1

  • CTR (float, optional) – Current Transformer Ratio, default=1

  • VTR (float, optional) – Voltage Transformer Ratio, default=1

Returns:

  • ZoneOff (float) – Zone Offset in ohms.

  • Z1dia (float) – Zone 1 diameter in ohms.

  • Z2dia (float) – Zone 2 diameter in ohms.
