Electric (not electronic) circuit simulation

Electric (not electronic) circuit simulation

Electric (not electronic) circuit simulation

Does anybody knows of a software that can draw and calculate steady state single phase electrical circuits? I have SKM but is not what I want. SKM is an excellent program but it can't draw the single phase schematic diagrams, including phase, neutral, and equipment grounding conductors and then calculate the voltage at each equipment during a ground fault.

I summary, I need a software that can draw single phase schematics, including the utility information, transformers, wires (phase, neutrals, and equipment grounding conductors). Then simulate a ground fault in a bus, and obtain the ground fault current in the circuit and the voltage of each equipment affected by this fault.

I have tried Circuit Lab, Spice, Quacs, etc. They all are good to draw the schematics, but are more oriented to analyze electronic circuits with AC simulations in time domain or frequency domain (changing values with respect to time or frequency). But not a steady state ground fault condition modeling the utility with a maximum fault and nominal voltage.

Any help will be appreciated.


RE: Electric (not electronic) circuit simulation

I use PSIM for simple and more complex simulations. Especially power. It doesn't cost too much and is easy to learn for the occasional user (like me). Have used it for anything from steady state to transient solutions and simple RL circuitry like ground grids to frequency inverters and AS-i communication.
