Attribute
Public PU
  efd1
Details:
Notes: Exciter voltage at which exciter saturation is defined (Efd1).  Typical Value = 3.05.<br/>
Public PU
  efd2
Details:
Notes: Exciter voltage at which exciter saturation is defined (Efd2).  Typical Value = 2.29.<br/>
Public Boolean
  exclim
Details:
Notes: (exclim).  IEEE standard is ambiguous about lower limit on exciter output.<br/>true = a lower limit of zero is applied to integrator output<br/>false = a lower limit of zero is not applied to integrator output.<br/>Typical Value = true.<br/>
Public PU
  ka
Details:
Notes: Voltage regulator gain (Ka).  Typical Value = 300.<br/>
Public PU
  ke
Details:
Notes: Exciter constant related to self-excited field (Ke).  If Ke is entered as zero, the model calculates an effective value of Ke such that the initial condition value of Vr is zero. The zero value of Ke is not changed.  If Ke is entered as non-zero, its value is used directly, without change.  Typical Value = 1.<br/>

  kf
Details:
Notes: Excitation control system stabilizer gain (Kf).  Typical Value = 0.1.<br/>
Public PU
