[Electrical Power Systems] Help with Thevenin Equivalent Circuit Positive Sequence

Thread Starter

Hello, new forum member here, I am studying the calculations of short circuits in different electrical power systems at the institute, I have solved different types and in general I have no problems with the calculations, but sometimes there are exercises that are more complex like the one that I come to post here.

Problem: I need clues or tips to be able to reduce this circuit and be able to obtain the Thevenin equivalent circuit of the positive sequence where the fault is located (in the middle of the line Point P).

I attach what I have done and the problem. (Maybe I did something wrong within my development).

The correct answer is X1TH= j0,097, but I can't get to it.
