- •
We propose a method for simulating process of power system blackout.
- •
Activation of zone 3 of distance relays is recognized to be critical for blackout.
- •
A distance relay with highest activation in blackout is recognized as critical.
- •
We propose a probabilistic–deterministic approach for recognizing critical relays.
- •
Blocking minimum critical distance relays, substantially mitigate risk of blackout.
