Class Description
Current limitation model. The current limitation model combines the physical limits and the control limits.
Reference: IEC 61400-27-1:2015, 5.6.5.8.
Attributes
| Name | Type | Description |
|---|---|---|
| imax | PU | Maximum continuous current at the wind turbine terminals (imax). It is a type-dependent parameter. |
| imaxdip | PU | Maximum current during voltage dip at the wind turbine terminals (imaxdip). It is a project-dependent parameter. |
| kpqu | PU | Partial derivative of reactive current limit (Kpqu) versus voltage. It is a type-dependent parameter. |
| mdfslim | Boolean | Limitation of type 3 stator current (MDFSLim). MDFSLim = 1 for wind turbines type 4. It is a type-dependent parameter. |
| false= total current limitation (0 in the IEC model) | ||
| true=stator current limitation (1 in the IEC model). | ||
| mqpri | Boolean | Prioritisation of Q control during UVRT (Mqpri). It is a project-dependent parameter. |
| true = reactive power priority (1 in the IEC model) | ||
| false = active power priority (0 in the IEC model). | ||
| tufiltcl | Seconds | Voltage measurement filter time constant (Tufiltcl) (>= 0). It is a type-dependent parameter. |
| upqumax | PU | Wind turbine voltage in the operation point where zero reactive current can be delivered (upqumax). It is a type-dependent parameter. |
