Status :
Optional
Restriction :
The generator node and a turbine must be previously defined. For dynamic analyses only.
Purpose :
To define an electric generator
Details :
| Parameter | Description |
|---|---|
| INOD | Node of the low shaft linked to the drive train. |
| ITYP | type of control : 0 force |
| ID | Identification numer of the Wind Turbine component. |
| INOREAC | Point where the reaction moment (opposite of the imposed moment) is applied |
| GBRATIO | Ratio of the GEARBOX (winput/woutput), 1 if no gearbox |
| GBEFF | Gearbox efficiency, 1 if no gearbox. If the efficiency is less or equal 0 or strictly greater than 1, it is considered that the gearbox efficiency is function of the velocity. The efficiency is then defined by a predefined table (*TABLEMCOL) which number is defined by IEFF |
| STIFF | Rotational stiffness of Gearbox + HSS : This is not used and should be defined (added) to the shaft properties. |
| DAMP | Rotational damping of Gearbox +HSS : This is not used and should be defined (added) to the shaft properties. |
| POWER | Generator power (W) |
| MTRL | Maximum torque rate limit (N.m.s-1) |
| MINGT | Minimum generator torque (N.m) |
| MAXGT | Maximum generator torque (N.m) |
| EFF | Generator efficiency |
| IEFF | If GBEFF is less than 0, the gearbox efficiency is defined by a table, the table ID is IEFF |
