Changing SimPowerSystem Block Parameter during simulation runtime

Hi all,

May I know how can I change a SimPowerSystem block parameters during simulation runtime? (I need to change one of the parameters of the Three-Phase RLC Load during simulation runtime).

I have read the documents regarding non-tunable block parameters. However, is there any way I can work around this problem?

I would really appreciate any help or comments.

Thank you!!

Best Regards, Rachel

Hey Rach,

did you ever figure out how to solve this issue? I've been having trouble implementing the same concept. Please help and thanks!

If the block you are using defines its parameter(s) as non-tunable, then there is no way to tune it. You might need to find an alternate implementation.

If this block's parameter is tunable, then all you need to do is to define your parameter in MATLAB's base workspace and to tune it while simulation is running, you can change the value in MATLAB base workspace then press ctrl+D (or update diagram) on your Simulink mode. This way the new value will be updated in the Simulink model.
