A new approach for mitigating blackout risk by blocking minimum critical distance relays
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 probabilisticdeterministic approach for recognizing critical relays. Blocking minimum critical distance relays, substantially mitigate risk of blackout.
