How to fix initial states of switches in circuit SIMULINK SIMSCAPE

16 views (last 30 days)
I'm testing my grid for the thesis which i need to be done, so here is the error which i get when I start my simulation:
"Initial states of switches specified in your circuit produce 1 topological error(s) at t=0 Check the 1 circuit equations listed below: Equations for state variables dependending directly on sources: +Il_transfo_1_Lm: TE-TO_T2 -176.271*Il_transfo_1_winding_2: TE-TO_T2 +Il_transfo_2_Lm: TE-TO_T2 -176.271*Il_transfo_2_winding_2: TE-TO_T2 +170.475*Il_transfo_3_Lm: TE-TO_T2 -169.475*Il_transfo_3_winding_1: TE-TO_T2 -30049.8*Il_transfo_3_winding_2: TE-TO_T2 +2.65497e-24*U_A: TE-TO_G2 +3.02552e-07*U_B: TE-TO_G2 -3.02552e-07*U_C: TE-TO_G2 = 0"
What I am supposed to do and how am supposed to do it. Pls help.

The mostly likely issue is that in certain configurations, your model can't actually simulate. This could be due to current source being in series or some other modelling issue. Also, can you share your model or at least a screen shot of it to get more specific recomendations?
