Transformer Losses with nonlinear load

Hello, my problem is how I can simulate in simulink power losses in transformer witch is loaded by nonlinear load. Transformer is Three-phase. I have electroenergetic system here is a link with my block diagram.

First, run your model under nonlinear load and record the current harmonics. Then, use IEEE Std C57.110TM-2008 to calculate power losses considering different current harmonics.

can you tell me how to find the current harmonics in matlab. thanks
