Dynamic Load Block MATLAB documenation

I am lloking for Dynamic Load change using the block provided in "openExample('simscapeelectricalsps/DynamicLoadExample')"

Can you please provide me proper ducmentaion how to use the block "Three-Phase Dynamic Load"?

Lookking for answer.

Hi Jagdish,

Check this documentation - https://www.mathworks.com/help/sps/powersys/ref/threephasedynamicload.html

Dear Piyush,

Thank you for your response.

Suppose that I am looking for change in load at different power factor, where PF changes substancially in an automated formated. How to use the block you mentioned?

Hi Jagdish,

If you click on the block, you will get "Configuration Parameter" dialog box.

Select the check box for "External Control of PQ". Apply this configuration.

You will get one input port for "PQ" in the block.

To automate the process, If you know power factor and active power demand then you can use a "MATLAB function" block containing below script -

function y = fcn(powerFactor, P)
S = P/powerFactor;
Q = sqrt(S^2 - P^2);

y = [P Q];

This MATLAB function takes 'Power factor' and 'Active Power' demand as input.

By providing appropriate values for P and powerfactor, the Three-phase dynamic load can be varied.
