ExcSCRX
Class Description
Simple excitation system with generic characteristics typical of many excitation systems; intended for use where negative field current could be a problem.
Attributes
| Name | Type | Description |
|---|---|---|
| cswitch | Boolean | Power source switch (<i>Cswitch</i>). true = fixed voltage of 1.0 PU false = generator terminal voltage. |
| emax | PU | Maximum field voltage output (<i>Emax</i>) (> ExcSCRX.emin). Typical value = 5. |
| emin | PU | Minimum field voltage output (<i>Emin</i>) (< ExcSCRX.emax). Typical value = 0. |
| k | PU | Gain (<i>K</i>) (> 0). Typical value = 200. |
| rcrfd | Float | Ratio of field discharge resistance to field winding resistance ([<i>rc / rfd]</i>). Typical value = 0. |
| tatb | Float | Gain reduction ratio of lag-lead element ([<i>Ta</i> / <i>Tb</i>]). The parameter <i>Ta</i> is not defined explicitly. Typical value = 0.1. |
| tb | Seconds | Denominator time constant of lag-lead block (<i>Tb</i>) (>= 0). Typical value = 10. |
| te | Seconds | Time constant of gain block (<i>Te</i>) (> 0). Typical value = 0,02. |
