Attributes
| Name | Type | Description |
|---|---|---|
| efd1 | PU | Exciter voltage at which exciter saturation is defined (<i>Efd</i><i><sub>1</sub></i>) (> 0). Typical value = 3,1. |
| efd2 | PU | Exciter voltage at which exciter saturation is defined (<i>Efd</i><i><sub>2</sub></i>) (> 0). Typical value = 2,3. |
| efdmax | PU | Maximum voltage exciter output limiter (<i>Efdmax</i>) (> ExcDC1A.efdmin). Typical value = 99. |
| efdmin | PU | Minimum voltage exciter output limiter (<i>Efdmin</i>) (< ExcDC1A.edfmax). Typical value = -99. |
| exclim | Boolean | (<i>exclim</i>). 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 is not applied to integrator output. Typical value = true. |
| ka | PU | Voltage regulator gain (<i>Ka</i>) (> 0). Typical value = 46. |
| ke | PU | Exciter constant related to self-excited field (<i>Ke</i>). Typical value = 0. |
| kf | PU | Excitation control system stabilizer gain (<i>Kf</i>) (>= 0). Typical value = 0,1. |
| ks | PU | Coefficient to allow different usage of the model-speed coefficient (<i>Ks</i>). Typical value = 0. |
| seefd1 | Float | Exciter saturation function value at the corresponding exciter voltage, <i>Efd</i><i><sub>1</sub></i> (<i>Se[Eefd</i><i><sub>1</sub></i><i>]</i>) (>= 0). Typical value = 0,33. |
| seefd2 | Float | Exciter saturation function value at the corresponding exciter voltage, <i>Efd</i><i><sub>2</sub></i> (<i>Se[Eefd</i><i><sub>2</sub></i><i>]</i>) (>= 0). Typical value = 0,1. |
| ta | Seconds | Voltage regulator time constant (<i>Ta</i>) (> 0). Typical value = 0,06. |
| tb | Seconds | Voltage regulator time constant (<i>Tb</i>) (>= 0). Typical value = 0. |
| tc | Seconds | Voltage regulator time constant (<i>Tc</i>) (>= 0). Typical value = 0. |
| te | Seconds | Exciter time constant, integration rate associated with exciter control (<i>Te</i>) (> 0). Typical value = 0,46. |
| tf | Seconds | Excitation control system stabilizer time constant (<i>Tf</i>) (> 0). Typical value = 1. |
| vrmax | PU | Maximum voltage regulator output (<i>Vrmax</i>) (> ExcDC1A.vrmin). Typical value = 1. |
| vrmin | PU | Minimum voltage regulator output (<i>Vrmin</i>) (< 0 and < ExcDC1A.vrmax). Typical value = -0,9. |
