Attributes

Name Type Description
efd1 PU Exciter voltage at which exciter saturation is defined (Efd1) (> 0). Typical value = 2,6.
efd2 PU Exciter voltage at which exciter saturation is defined (Efd2) (> 0). Typical value = 3,45.
efdlim Boolean (Efdlim).
true = exciter output limiter is active
false = exciter output limiter not active.
Typical value = true.
efdmax PU Maximum voltage exciter output limiter (Efdmax) (> ExcDC3A.efdmin). Typical value = 99.
efdmin PU Minimum voltage exciter output limiter (Efdmin) (< ExcDC3A.efdmax). Typical value = -99.
exclim Boolean (exclim). IEEE standard is ambiguous about lower limit on exciter output.
true = a lower limit of zero is applied to integrator output
false = a lower limit of zero not applied to integrator output.
Typical value = true.
ke PU Exciter constant related to self-excited field (Ke). Typical value = 1.
kr PU Deadband (Kr). Typical value = 0.
ks PU Coefficient to allow different usage of the model-speed coefficient (Ks). Typical value = 0.
kv PU Fast raise/lower contact setting (Kv) (> 0). Typical value = 0,05.
