Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This package contains space phasor transformation functions for use in calculations:
  • ToSpacePhasor: transforms a set of three-phase values to space phasor and zero sequence system
  • FromSpacePhasor: transforms a space phasor and zero sequence system to a set of three-phase values
  • Rotator: rotates a space phasor (from one coordinate system into another)
  • ToPolar: Converts a space phasor from rectangular coordinates to polar coordinates
  • FromPolar: Converts a space phasor from polar coordinates to rectangular coordinates

Space phasors are defined as vectors of length = 2, the first element representing the real part and the second element representing the imaginary part of the space phasor.
