In the Simulink help choose 1) SimPowerSystems examples 2) Specialized Technology 3) Machine Models 4) Performance of Three PSS for Interarea Oscillations

Description: "This example shows three Power System Stabilizers (PSS) models using Kundur's four-machine two-area test system."

I have seen this example but i am interested in getting the state space model of the system. When i try to linearize my model using 'Power_analyze' it give me state space with generators and nonlinear elements. and i cant see their state space so any idea how to get them as to do eigenvalue analysis on the system

Dear Imran,

I recommend you study the following manuscript in which Small Signal Stability has been modeled and implemented using MATLAB programming. It would be helpful for you research.

Data Small-Signal Stability Analysis using MATLAB Programming (in Persian)

Thank you very much Morteza for your reply. I have already seen your paper you mentioned and its quite interesting but what i was hoping to get is linearizing the system in simpower system instead of simulink general environment using built in models as i am working on model reduction of the system for which i need system matrices and then i am hoping to simulate transient analysis with me reduce system

You follow this book. It is presented your problem in very lucid way. you can easily understand and derive state space model of any multimachine power system.

Dear Morteza Shabanzadeh,

 Could you please send the English version of the report which you have uploaded earlier. Cause It will be helpful if it is in English for me to work with the stability problem which am dealing with right now.

In the mentioned problem, tools such as the Power System Toolbox (PST), or the Power System Analysis Toolbox (PSAT) are more easier than the SimPowerSystems toolbox for an elaborated small-signal stability analysis. In addition, they are open source tools i.e. you can modify their liberary models, and add new models.

I thin you can easily build your dynamic model in Simulink and use the linmodel function to get the state space for your system
