EMTDC Runtime Error

Hello, I have a EMTDC runtime error on my simulation. The simulation will run for 10-11 seconds and will then display this error, does anyone know why? (please see attached)

Hello

You simulation is crashing and it will take some time to diagnose the problem. There is no quick answer and thus is beyond what I support on this forum. If no one else here can help you, then I would suggest that you contact us at

support@pscad.com

Send in your project to us there and I will open up a support ticket for you and we can spend some time diagnosing the problem.

Hello,

your problem is very simple.
please check the Three-Phase Fault
take another value for the Fault ON Resistance, like 0.2 ohm
this should work ...!

for more information about this point check the PSCAD Software manual concerining the three phase fault component:
Enter a small value to represent the branch resistance during a faulted state. This value is usually in the order of 0.01 (default), and is internally limited so that it is always less than 1% of the Fault OFF Resistance [ W ].

NOTE: Although this parameter is configured to take a variable signal, it cannot be changed dynamically. The value of the signal at first time step is taken as the ON resistance, independent of the project startup method (i.e. from Data File or Snapshot File). This allows the ability to change the ON resistance when the project is started from a snapshot, without invalidating the snapshot file.

NOTE: If this value is less than the ideal branch threshold, the fault will be modeled as an ideal branch while in the faulted state.

I hope this will help you.

Best Regards,
