Is there any way to change these blocks with code?

I need to change the fault type in my simulation during the simualtion on a line.

Hi Ehsan,

I understand that you would like to alter the default settings of the checkbox in the “Three-Phase Fault” Block parameter via code/script.

I would suggest you use “set_param” function in MATLAB for changing the parameter in Simulink. For your specific needs, you can change the parameter as follows:

% Open or create a Simulink model
modelName = 'myModel';  % Replace 'myModel' with your model name
open_system(modelName);
% Get the block path/name
blockName = 'myModel/Three-Phase Fault'; 
% Set the checkbox on/off 
set_param(blockName,'FaultA','off');
get_param(blockName,'FaultA')
save_system(modelName);

For more imformation on “set_param”, you can refer to the following link.

Hope this will resolve your query!

Thank you very much for your help, it works greatly !

But one more question, I couldnt uncheck the "Ground", How can I do this?

[Mann Baidi]

set the parameter for the "Ground" phase as follows:

set_param(blockName,'GroundFault','off');
