Updating the Active Power of a Three-Phase Parallel RLC Load during Simulation Run Time

Hi all,

I have a simulink simulation that runs for 20s. At every 5s, it will perform a new set of calculations and update the variable 'R' in the workspace automatically via the 'assignin' command.

Now I would need to read in this updated variable into the Active Power (under block parameters) of the Three-Phase Parallel RLC Load in my simulink model. May I know if the set_param command is able to perform this function in this situation? Or is it impossible to write into the Active Power of the Three-Phase Parallel RLC Load?

Any help or advice would be greatly appreciated! Thank you!

Best Regards, Rachel

Probably best to use variable Resistor/inductor/capacitor in this situation. It is then possible to update the value during simulation.
