MATLAB/Simulink transient stability analysis of a multimachine power system- generator accelerating power diagram

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.

Hi Almir,
I am also doing the same simulation. The gain pi*f/H is different for 3 generators as 'H' is different. The value of stored kinetic energy at rated speed is given for 3 generators, 2364, 640, and 301 respectively. 'H' can be found by dividing stored kinetic energy by base MVA, which is 100. H1 = 2.364, H2 = 0.64, H3 = 0.301 And so, the gain values are 79.7358, 294.5243, and 626.2311 respectively for generators 1 to 3. Hope it helps.
I am also having problem with this simulation. Could you send me yours simulation in light of facilitate to find my mistake. Thanks
i am also doing the same simulation..Can you please tell me after load flow analysis how to use the value of that load flow analysis in other..like i eant the value of that E1 del1 E2 del2...
Anyone please help me?
Can any one provide me the program coding for the above paper ?

hey almir and muthuraj
iam also working on the same problem. and there are errors and I don't know what im doing wrong. I will be really grateful to you. if you could mail me the simulation model. please.
thanks
