Wind turbine


Scaling scheme

It is possible to scale geometry and mass parameters of the wind turbine by choosing a scaling scheme. It is possible to change scheme at any time.

Blades are NOT affected by scaling. If you want to scale a blade that is done by making a new blade in the Blade database. Likewise, a support section imported from file is not affected by scaling.

When a part is scaled (by using Global or Local scaling), the relevant parameters in the Parameters window are not (automatically) changed. However, the values used when creating the model are shown in the Information window.

It is possible to go back from Global scaling or Local scaling to No scaling, or between Global and Loacal scaling. In these cases, all relevant parameters are updated with their current scaling factors. After a switch of scaling scheme, all relevant parameters are updated by taking their scale into consideration, and the scale is set to 1.0. After this, the values in the Parameters window and the Information window are the same.


No scaling (default):

This is the traditional mode of engineering software. Model parameter values are set and changed by you one-by-one. The local options for scaling are not enabled. You will not be bothered with any scaling scheme or scaling factors.

Global scaling:

This option activates the Global scaling factor parameter. This factor will quite intelligently (rule-of-thumb) scale the whole wind turbine (i.e. global means the whole wind turbine in this contexct, except blades).

Local scaling:

Local scaling factors can be set where this is relevant.

Global scale factor

All relevant parts of the wind turbine is scaled with this factor. Only visible if Scaling scheme is set to Global scaling.

This factor does not affect neither blades nor support section imported from file. To scale the blades, you have to copy the current blade and enter the required length. This can be done in the Blade database.

- If you enter a value for Global scaling and then return to No scaling, the model will still be defined by the scale you entered initially. If you want to reverse the model to its initial size, you will have to set the Global scale to 1.0 and then go back to No scaling.
If you enter a value for Global scaling, the parameters shown for the different parts will still be the ones of the original model, but the model will in effect be scaled (as can be seen in the Information pane of the relevant part). For example, the default onshore template has a tubular tower that is 87.6 m tall. If the global scaling is set to 0.5, the tubular tower will be scaled down to 43.6 m, as can be see in the Information pane, but the height displayed in the Properties pane will still be 87.6 m. If you then set the scaling scheme to No scaling, the height shown in the Properties pane will match the Information pane at 46.3 m.
