MATLAB/SIMULINK-BASED  MULTI-MACHINE TRANSIENT STABILITY PROGRAMMES
------------------------------------------------------------------
A) Folder name: KRP_appr.

This folder contains a transient stability programme based on 
the book 'Power System Dynamics-Stability and Control' by K.R. Padiyar. 
BS Publications, Hyderabad, India 2002.

Features of the Programme:

1. Full-blown model (2.2 model) for  synchronous machines.
2. Permits any simplified models, even classical model for generators.
3. Six IEEE-type exciters.
4. Three IEEE-type turbine systems with associated speed governor systems.
5. Four IEEE-type Power System Stabilizers (PSS).
6. Flexibility to use any kind of exciter/PSS/turbine with a given generator.
7. Voltage- and frequency-dependent static load models.
8. No restriction on the size of the system.
   
Files provided in KRP_appr:

a) 4_machine: Contains files related to 4 machine, 10 bus power system.
   gen.dat  : 2.2 model
   gen11.dat: 1.1 model (rename it as gen.dat for making it active.)
   gen00.dat: classical model (rename it as gen.dat for making it active.)

b) 50_machine: Contains files related to 50 machine, 145 bus, IEEE power system. 
c) smib: Contains files related to the example 6.6 in the book 'Power System  
   Dynamics-Stability and Control' by K.R. Padiyar.
d) trans_manual.pdf: Manual for transient stability programme.

B) Folder name: Kundur_appr.

This folder contains a transient stability programme based on 
the book  `Power  System Stability and Control' by P. Kundur,  McGraw-Hill Inc., New York, 1994.

Features of the Programme (in addition to the above list):

 9. IEEE Std. 1110-2002 specified generator saturation model. 
10. Stability studies for unsymmetrical faults (LG, LL, LLG, and one/two open- 
    conductor(s) faults).
11. Flexibility to use different fault clearing procedures.

Files provided in Kundur_appr:

The main folders:
For symmetrical fault study: symm_faults.
For unsymmetrical fault study: unsymm_faults.
The following 3 sub-folders are there in each of the above 2 main folders:

a) 4_machine+: Contains files related to 4 machine, 10 bus power system (adopted  
  from the book 'Power System Dynamics-Stability and Control' by K.R. Padiyar.
  gen.dat  : 2.2 model
  gen11.dat: 1.1 model (rename it as gen.dat for making it active.)
  gen00.dat: classical model (rename it as gen.dat for making it active.)

b) smib: Contains files related to the example 6.6 in the book 'Power System  
   Dynamics-Stability and Control' by K.R. Padiyar.
c) 50_machine: Contains files related to 50 machine, 145 bus, IEEE power system. 
d) Manual for symmetrical faults: manual_sym.pdf
e) Manual for unsymmetrical faults: manual_unsym.pdf
