Dear! I am using pss/e 33. i have been run power system connect with wind farm via HVDC VSC. However system is show Network not converged when simulation one faults in power system. Can you give me some suggest for this situation? Thank you.
Yes. Thank you so much.
I after clear fault have the situation during nearly 0,5 - 1 second network not converged. After that parameter show NaN value.
You may try the following: -Try to decrease the fault impedance value (e.g. -1e6 MVA). Remember that a fault is represented as a discontinuity in the program and treats it in a different way. -Decrease the time step (e.g. 0.0041667 ms). Did you develop a detailed wind farm model? Check the X/R ratio
It is normal to get network not converged when simulating a solid three phase fault. You can try to increase the number of iterations in dynamic solution options. Does the network converge after fault clearing?
