DFIG based wind with AC DC converter

Hello i want to simulate a DFIG based wind with AC DC converter. I am using a simple universal bridge in order to make it. I have an error Complex signal mismatch. Input port 1 of 'power_windff/Wind Turbine Doubly-Fed Induction Generator (Phasor Type)/Generator & Converters/Ia (pu)' expects a signal of numeric type real.

I dont understand how to correct it.

Can someone help me ?

I am not sure about the entire technical details of the Model that you are trying to simulate. However, this might be a possible resolution.

• Try making use of ‘Complex-to-Real-Image' converter block and then connect the Real outport of the converter to the blocks or ports which are dependent on this signal in the model.
• To find the appropriate location to connect the block, click on the error and it would re-route you to the exact location.
• The logic behind using this converter is that sometimes certain blocks do not accept complex numbers as inputs and therefore we can consider splitting the signal into real and imaginary parts.
