WindContCurrLimIEC
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 (<i>i</i><i><sub>max</sub></i>). It is a type-dependent parameter. |
| imaxdip | PU | Maximum current during voltage dip at the wind turbine terminals (<i>i</i><i><sub>maxdip</sub></i>). It is a project-dependent parameter. |
| kpqu | PU | Partial derivative of reactive current limit (<i>K</i><i><sub>pqu</sub></i>) versus voltage. It is a type-dependent parameter. |
| mdfslim | Boolean | Limitation of type 3 stator current (<i>M</i><i><sub>DFSLim</sub></i>). <i>M</i><i><sub>DFSLim</sub></i><sub> </sub>= 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 (<i>M</i><i><sub>qpri</sub></i>). 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 (<i>T</i><i><sub>ufiltcl</sub></i>) (>= 0). It is a type-dependent parameter. |
| upqumax | PU | Wind turbine voltage in the operation point where zero reactive current can be delivered (<i>u</i><i><sub>pqumax</sub></i>). It is a type-dependent parameter. |
