I have created a Power system model in Simulink .I need to do Stability study for which i am in need to calculate THE EIGEN VALUES of the Power system model.I googled and learned about Power_analyze command to get the state matrices (A,B,C,D) from which eig(A) eigen values can be calculated.But what is the problem is the state variables are inductor currents and capacitor voltages only.If no inductor or capacitor is used(say Transmission line etc),it is showing there is no state variables for this model.But if i use an generator then delta,omega ,Induced emf(Eqp,Edp),Efd are state variables of the synchrounous generator.How to get that state variables for stability study.Expecting response.Thanks.

I need same thing, too. How to find eigenvalues for power systems to make stability analysis ?

If I am not wrong, you have to do linearization in Matlab simulink to get the state matrices, ABCD. Can you share me the simulink model to comment further.

Thanks
