All synchronous machine detailed types use a subset of the same data parameters and input/output variables.  <br/>The several variations differ in the following ways:<br/><ul>
<li>The number of  equivalent windings that are included</li><li>The way in which saturation is incorporated into the model.</li><li>Whether or not “subtransient saliency” (<b>X''q</b> not = <b>X''d</b>) is represented.</li></ul>
<b>Note:</b> It is not necessary for each simulation tool to have separate models for each of the model types.  The same model can often be used for several types by alternative logic within the model.  Also, differences in saturation representation may not result in significant model performance differences so model substitutions are often acceptable. <br/>
Attribute
Public Float
  efdBaseRatio
Details:
Notes: Ratio (Exciter voltage/Generator voltage) of Efd bases of exciter and generator models. Typical Value = 1.<br/>
Public IfdBaseKind
  ifdBaseType
Details:
Notes: Excitation base system mode. It should be equal to the value of WLMDV given by the user. WLMDV is the per unit ratio between the field voltage and the excitation current: Efd = WLMDV*Ifd. Typical Value = ifag.<br/>
Public Float
  saturationFactor120QAxis
Details:
Notes: Q-axis saturation factor at 120% of rated terminal voltage (S12q) (#gt;=S1q).  Typical Value = 0.12.<br/>
Public Float
  saturationFactorQAxis
Details:
Notes: Q-axis saturation factor at rated terminal voltage (S1q) (#gt;= 0). Typical Value = 0.02.<br/>
