Hi guys*

I'm desperate.. last few weeks I'm trying to make some simple example of power swing in NEPLAN* but I don't know how to do it. I tried it on simple and complex grid* but nothing.
Does anyone knows how to simulate power swing for some grid* even in the simplest grid(two generators* two trans* two line). How to implement power swing protection in distance relay(for example in REL316)? with CCT? How to plot impedance trajektory of distance relay?
I followed youtube instructions for distance relay and dynamic analysis but didn't solve this.

Any help is appreciated.
