Pss1
Class Description
Italian PSS with three inputs (speed, frequency, power).
Attributes
| Name | Type | Description |
|---|---|---|
| kf | Float | Frequency power input gain (<i>K</i><i><sub>F</sub></i>). Typical value = 5. |
| komega | Float | Shaft speed power input gain (<i>K</i><i><sub>omega</sub></i>). Typical value = 0. |
| kpe | Float | Electric power input gain (<i>K</i><i><sub>PE</sub></i>). Typical value = 0,3. |
| ks | Float | PSS gain (<i>Ks</i>). Typical value = 1. |
| pmin | PU | Minimum power PSS enabling (<i>Pmin</i>). Typical value = 0,25. |
| t10 | Seconds | Lead/lag time constant (<i>T</i><i><sub>10</sub></i>) (>= 0). Typical value = 0. |
| t5 | Seconds | Washout (<i>T</i><i><sub>5</sub></i>) (>= 0). Typical value = 3,5. |
| t6 | Seconds | Filter time constant (<i>T</i><i><sub>6</sub></i>) (>= 0). Typical value = 0. |
| t7 | Seconds | Lead/lag time constant (<i>T</i><i><sub>7</sub></i>) (>= 0). If = 0, both blocks are bypassed. Typical value = 0. |
