inv_symmetrical_components

typhoon.test.transformations.inv_symmetrical_components(V0, V1, V2)

Calculates the a, b and c phasors from symmetrical components.

Parameters:

  • V0 (complex or Phasor) – Zero-sequence component of phase “a”.

  • V1 (complex or Phasor) – Positive-sequence component of phase “a”.

  • V2 (complex or Phasor) – Negative-sequence component of phase “a”.

Returns:

  • Va (same type as input) – Phase “a” component.

  • Vb (same type as input) – Phase “b” component.

  • Vc (same type as input) – Phase “c” component.

Examples

>>> from typhoon.types.phasors import Phasor
>>> from typhoon.test.transformations import inv_symmetrical_components

>>> Va = Phasor(mag=5, angle=53)
>>> Vb = Phasor(mag=7, angle=-164)
>>> Vc = Phasor(mag=7, angle=105)
>>> V0, V1, V2 = symmetrical_components(Va, Vb, Vc)

>>> Va_round, Vb_round, Vc_round = inv_symmetrical_components(V0, V1, V2)
>>> assert Va_round == Va
>>> assert Vb_round == Vb
>>> assert Vc_round == Vc
