unable to match the IEEE 34 Bus system results especially at bus 888 & 890 that is after a step down transformer.

I am trying to replicate the IEEE 34 Bus system using Simulink in Phasor Power GUI, But I am unable to match the results there is a minimum of 0.6% error in Bus Voltages and 0.6 degree angle difference. Except for large errors in buses 888, 890 & 860.

Below are the error results

If anybody requires the model I happy to share.

Looking forward for a solution.

Hi @Mohammed Rahamath Ali,

Can you share the model, so that I can replicate the issue on my end?

Hello Mohammed,

As far as I understand you want to to know more about the IEEE 34 bus implementation in Simulink.

Please find the below documnetation links for more information:

IEEE 34 bus distribution feeder phasor: https://in.mathworks.com/matlabcentral/fileexchange/123225-ieee-34-bus-distribution-feeder-phasor-simulink-model

IEEE 34 bus distribution feeder discreter model: https://in.mathworks.com/matlabcentral/fileexchange/123220-ieee-34-bus-distribution-feeder-discrete-simulink-model

I hope this helps!

Thank you for sharing the link with me. Can you help me to match the 34 system Bus voltage magnitude and angle with IEEE bench markk values. I have attached the discrete 34 bus system model after editing.

Thank you
