modelVspectrum

Ideal voltage spectrum, 3-phase dq0

Extends from Partials.VoltageBase (Voltage base, 3-phase dq0).

Information

Voltage spectrum with constant amplitude and phase when 'vType' is 'parameter',
with variable amplitude and phase when 'vType' is 'signal'.

In inertial abc-system the voltage-spectrum is given by the expression

  v_spec_ABC = sqrt(2/3)*sum_n(v0[n]*cos(h[n]*(theta + alpha_tot - k*2*pi/3)))
with
  k=0,1,2 for phase a,b,c
and
  alpha_tot = alpha + system.alpha0 + alpha0[n]
where
  alpha = vPhasor_in[2] (common phase) for signal input, else 0

Optional input:

  omega_in            angular frequency (if fType == "Signal")
  vPhasor_in          {modulation(v), common phase(v)}
   vPhasor_in[1] = 1  delivers the values for constant amplitudes v0
   vPhasor_in[1]      in SI or pu, depending on choice of 'units'
   vPhasor_in[2]      in rad
