symmetrical_components

typhoon.test.transformations.symmetrical_components(Va, Vb, Vc)

Calculates symmetrical values abc phasors.

Parameters:

  • Va (complex or phasor) – Phase “a” component.

  • Vb (complex or phasor) – Phase “b” component.

  • Vc (complex or phasor) – Phase “c” component.

Returns:

  • V0 (same type as input) – Zero-sequence component of phase “a”.

  • V1 (same type as input) – Positive-sequence component of phase “a”.

  • V2 (same type as input) – Negative-sequence component of phase “a”.

Examples

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