Standard 5 Bus System
Bus Data:
(MW) (MVAR) (MW) (MVAR)
1 1.06 0.00 0 0 0 0 ;
2 1.00 0.00 40 30 20 10 ;
3 1.00 0.00 00 0 45 15 ;
4 1.00 0.00 00 0 40 5 ;
5 1.00 0.00 00 0 60 10;
Line Data:
%----------------r-------x------------b-------Transformation Ratio-----
line = 1 2 0.02 0.06 0.03 1.0;
1 3 0.08 0.24 0.025 1.0;
2 3 0.06 0.18 0.02 1.0;
2 4 0.06 0.18 0.02 1.0;
2 5 0.04 0.12 0.015 1.0;
3 4 0.01 0.03 0.01 1.0;
4 5 0.08 0.24 0.025 1.0;
Line Power Flow Limits:
Line 1 = 175;
Line 2 = 79.87;
Line 3 = 82.5;
Line 4 = 82.5;
Line 5 = 87.5;
Line 6 = 142.88;
Line 7 = 79.87;
I have developed a Fast-Decoupled Load Flow program using the above model and data. To proceed with my work further, I want to develop a Simulink model of the Standard 5 Bus system. I am attaching the diagram for the same. After that I want to use a trained Neural Network to determine state of the system by reading Voltage magnitudes or MW power flow on the lines.
I have tried developing a single phase system for the above model, but I think its faulty. I am not properly acquainted with Simulink. Please help.

I need help for this too.Did you solve the problem ?

I developed the 3-phase model long back. Using PSAT you can also develop Single phase models to get accurate results of load flow methods. But I still can't get good results on 3-phase models with load flow.

I have problem with coding too. (Command:Unbalanced or unexpected parenthesis or bracket.)
