Blackout Prevention and Power System Self-Restoration

Blackouts of power systems occur in transmission networks (TNs) as the result of dangerous emergency overloading. These are followed by cascade tripping of transmission lines and power plants and, finally, by collapse of a power system. Since the known automatic emergency protection means are insufficiently universal, the authors propose an additional simple and reliable tool that would allow for turning off such a collapse, with fast self-restoration of normal operating condition within only ~100 seconds.
