Standard 5 Bus System

Bus Data:  
 Bus No.   V      delta   Gen      Gen      Load    Load
                          (MW)    (MVAR)    (MW)   (MVAR)

   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;

        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.)

Perform load flow and obtain the bus voltage and angles. Now use three phase voltage source and transmission line with correct data obtained from load flow. If you are interested in steady state result you can use phasor model.
