Presentation of Special Protection Scheme in Power System to Reduce Graphite Bomb Attacks Damages

Graphite bombs are modern and non-destructive weapons causing wide area blackouts in power systems by applying short circuit faults. In this paper, a special protection scheme is presented to deal with graphite bombs and prevent blackouts. In this method, substations are categorized according to the system response to their outage event. In next stage, special protection scheme for each group is designed according to the available communication infrastructure. Load shedding, islanding, generation trip are the methods utilized along each other to tackle blackouts. The proposed methods are tested on IEEE 39 bus test system in different operation scenarios. Simulation results prove the validity of the proposed method in dealing with graphite attacks.
