The code helps to determine bus admittance matrix or in other words Y bus matrix. Usually programmers exclude condition of reactance of generator connected to a bus. If solving by pen and paper, a reactor is connected between bus and ground. This inductive reactor has been included in code.

If we want to neglect ground reactor, I am assuming we set that value equal to zero?


Excellent, thanks for code

where is the ground reactor bus in ieee 14 bus system. could you please explain it?


Thank you mr abbas,
I want to create modified nodal matrix of a circuit. Can you help me?


Bro can I get code for three phase newton raphson/backward forward sweep load flow analysis code?

i would like to know if when you given the generator impedance you can include it in calculation of the ybus
