Hello. I have problem in MATLAB/Simulink to analyse transient stability of multimachine power system, from literature, I've attached here. I created complete simulink system model for transient stability study, and got system responses on diagrams (angular position of individual generators, relative angular positions and relative angular velocities), but I can't get diagram of generator accelerating powers. Well, it's approximately, but not the same. I think that problem is in the GAIN block. For every generator this parameter is different, but I don't know how to calculate this, which value to put in the block. I used equation pi*f/H (H- inertia), but results are just approximately. Probably it's different for all generators ( in my case one hydro and two steam). Generators data are in the end of this file. My english isn't so good, but I hope you'll understand my problem and help me, too. Thank you.
