Simulation of the third order model of synchronous genrator


Hi Everyone, I am trying to simulate the third-order model of the synchronous generator (figure below). but I have no idea how to do this. Any help would be great.

Hello Mazouz,

your best option to use one of the existing synchronous machines already in the simscape electrical library, they can match and exceed this level of fidelity.

If you really want to build this yourself. You can start in Simulink.

an equation of the type d(t) (dot) = w0*deltaw(t) is best represented using an integrator in simulink, so in Simulink implement d = integral (w0*deltaw(t). Please complete the Simulink onramp here before trying to move forward, and then research modelling differential equations in Simulink. https://www.mathworks.com/learn/tutorials/simulink-onramp.html
