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 (dFmax). It is a type-dependent parameter. |
fover | PU | Wind turbine over frequency protection activation threshold (fover). It is a project-dependent parameter. |
funder | PU | Wind turbine under frequency protection activation threshold (funder). It is a project-dependent parameter. |
mzc | Boolean | Zero crossing measurement mode (Mzc). 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 (TfMA) (>= 0). It is a type-dependent parameter. |
uover | PU | Wind turbine over voltage protection activation threshold (uover). It is a project-dependent parameter. |
uunder | PU | Wind turbine under voltage protection activation threshold (uunder). It is a project-dependent parameter. |
