Need help on an error regarding a Simulink model
I have a ongoing study on a model regarding insulation coordination which I downloaded from this link https://www.mathworks.com/matlabcentral/fileexchange/108549-insulation-coordination-in-a-generating-station/?s_tid=LandingPageTabfx, it shows an error when I tried to run the model. Not sure what I’m doing wrong, hoping for a solution.
I have attached the original file(project1F30X2_m) and a slightly modified version(model2).
Error Encountered: Specialized Power Systems cannot solve this circuit. Please check for one the following two possibilities : 1) The circuit solution is undetermined. This problem arises when transformers with no magnetization branch (Rm=inf; Lm=inf) are connected together. –> Specify a magnetizing branch with finite Rm and/or Lm parameter values. 2) Circuit solution is inuccurate due to a badly scaled circuit. This is usually caused by a too wide range of resistance values (ex 1e-6 ohm and 1e6 ohm in the same circuit). –> Try to reduce range of resistance values. For example, reduce snubber resistances.I have a ongoing study on a model regarding insulation coordination which I downloaded from this link https://www.mathworks.com/matlabcentral/fileexchange/108549-insulation-coordination-in-a-generating-station/?s_tid=LandingPageTabfx, it shows an error when I tried to run the model.
