Mask and Parameters
AVR Parameters
Expanding the "AC8B diagram" displays the block diagram in the parameters window.
| Name | Description | Unit | |
|---|---|---|---|
| Tr | Regulator input time constant. This input filter is not part of the standard and there are no typical values recommended. It was added for flexibility. NB This parameter can be set to zero if the filter is not used. | s | |
| Tdr | Derivative time constant control PID | s | |
| Kpr | Proportional gain PID control | ||
| Kdr | Derivative gain PID control | ||
| Kir | Integral gain PID control | ||
| Ka | AVR filter gain | - | |
| Ta | AVR filter time constant | s | |
| VRmax | Maximum regulator internal voltage | pu | |
| VRmin | Minimum regulator internal voltage | pu | |
Exciter Parameters
