Your turbine "Wind speed (m/s)" signal is fed from the port labeled (1) . There are a couple of signal splits that could potentially be providing input.
(1)---+---> %LINE A
|
--------+ %LINE B
|
|________ %LINE C
The right of the one I have marked Line A is one-way into the Turbine Wind Speed (m/s) signal, so it cannot be a signal source.
If you follow the one I marked as Line B left it feeds into the Pitch Angle Controller1 as the input signal Wind Speed, and so cannot be a signal source either.
If you follow the bottom line I have marked as Line C then you ca nsee it proceeds over to the upper-right scope as an input there. Therefore that branch cannot be a signal source either.
That leaves just the port (1) as the signal source. And in turn that means you cannot run the model without having some other model providing data onto port (1).
