Limit of voltage variation

I work with the 34th edition of the software on the same 39-bus system that is referenced on your site. And I do all the dynamic simulation steps without any errors, and the waveforms are also closely matched. But the range of voltage changes for each turmoil does not change from 1.05 to 0.95 range ... Is there some limitations? I'm so in a hurry if you can. Thank you

Hi I work with the 34th version of this software and on the 39 Bus system (referred to on this site). All the simulation steps are done without error. And the output of the voltage waveform is also acceptable (during the fault). And .dyr file Also, it was tested in the presence of a generator, Excitation,Turbine-Governor and load a model with and without them. But the problem is that by applying any error in the system (each fault line for 80 ms), the voltage range does not change from 0.95 to 1.05 and is stable! The question is, is there any setting that makes this a limitation? What can be connected to? Thank you

The bus voltage should become 0 when you apply a solid fault at a bus. What is you disturbance? A bus fault or an in-line fault? What do mean with "output of the voltage waveform is also acceptable (during the fault)."
