Creating governor and exciter for generator model using simscape electrical.

Hello

I am trying to create a governor and exciter for a model of a diesel generator. I would like to have external Wref and Vref values as inputs to the governor and exciter so that the voltage and frequency are controllable. I already have the control logic just need some help with these two items. I have attcached my model. Thank you.

Hi Yazeed,

I understand that you want to load external input data from a workspace for simulating the model.

You could consider using the ‘Input’ parameter in the ‘Data Import/Export’ pane of ‘Configuration Parameters’. It loads input data from a workspace before the simulation begins and can be used using “Input” ports. You may read more about this in the documentation:

Another method is to use the “From Workspace” block. It reads data from a workspace and provides the data as a signal at the block’s output. The data must be in a timeseries, matrix, or structure format. You may read more about the block in the documentation:

https://www.mathworks.com/help/releases/R2023a/simulink/slref/fromworkspace.html

I see from the model that it expects physical signal. To convert a Simulink signal to a physical signal, you may use the “Simulink-PS Converter” block.

I hope this helps!
