modelVspectrum

Ideal voltage spectrum, 1-phase

Extends from Partials.ACvoltageBase (AC voltage base).

Information

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

The voltage-spectrum is given by the expression

  v_spec = sqrt(2)*veff*sum_n(cos(h[n]*(theta + alpha_tot[n])))
with
  alpha_tot[n] = 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
