Hi Mohammed,

The Electrical Angle of the Rotor Θe (degrees) can be automatically computed using the Load Flow tool or the Machine Initialization tool of the “powergui” block. You may refer to the “Parameters Tab for Synchronous Machine SI Fundamental” section for more detail. To access the documentation in MATLAB R2018a, you may use the following command:

web(fullfile(docroot, 'physmod/sps/powersys/ref/synchronousmachine.html'))   

Further detail on the usage of the Load Flow and Machine Initialization Tools in the “powergui” block can be found in the documentation below.

web(fullfile(docroot, 'physmod/sps/powersys/ref/powergui.html')) 

Please note that this is applicable until MATLAB R2020b. Starting from R2021a, it appears that there have been some changes due to which the block is not present and is instead present as a model in the Examples section.
