WindProtectionIEC
Class Description
The grid protection model includes protection against over- and under-voltage, and against over- and under-frequency. Reference: IEC 61400-27-1:2015, 5.6.6.
Attributes
| Name | Type | Description |
|---|---|---|
| dfimax | PU | Maximum rate of change of frequency (<i>dF</i><i><sub>max</sub></i>). It is a type-dependent parameter. |
| fover | PU | Wind turbine over frequency protection activation threshold (<i>f</i><i><sub>over</sub></i>). It is a project-dependent parameter. |
| funder | PU | Wind turbine under frequency protection activation threshold (<i>f</i><i><sub>under</sub></i>). It is a project-dependent parameter. |
| mzc | Boolean | Zero crossing measurement mode (<i>Mzc</i>). It is a type-dependent parameter. true = WT protection system uses zero crossings to detect frequency (1 in the IEC model) false = WT protection system does not use zero crossings to detect frequency (0 in the IEC model). |
| tfma | Seconds | Time interval of moving average window (<i>TfMA</i>) (>= 0). It is a type-dependent parameter. |
| uover | PU | Wind turbine over voltage protection activation threshold (<i>u</i><i><sub>over</sub></i>). It is a project-dependent parameter. |
| uunder | PU | Wind turbine under voltage protection activation threshold (<i>u</i><i><sub>under</sub></i>). It is a project-dependent parameter. |
