WindTurbinePower:
--------------------------------------------------------------------------
Compute the power from a wind turbine.
If tip speed ratio is input it will compute the torque
and rotational speed.
The power coefficient "cP" can be specified in one of several ways:
* A fixed value of cP can be given explicitly.
* The input cP can be a function name of the form:
- fun( lambda ) -OR-
- fun( lambda, beta )
* If cP is empty:
- if lambda and beta are not provided, by default cP = 0.44
- if only lambda is provided, cP is computed using the
CPvsTipSpeedRatio function.
- if both lambda and beta are provided, cP is computed using the
CP2D function.
Type WindTurbinePower for a demo.
