Presentation of Tehran Power System Islanding Plan to Avoiding Blackout due to Graphite Bombardment
Abstract:   (1027 Views)
Graphite bomb is a non-destructive weapon that is used for disturbing electrical power supply and blackouts. Cascading failures and blackouts are the most significant threats for power system security. A power system will be collapsed if the process of cascading failures proceeds by further line tripping. In this paper, a new method for Tehran power system islanding is proposed to encountering graphite attack and substation outage. Based on the proposed method, after the graphite bombs is released on electric substations, substation outage and islanding power system commands is occured. Thus, a new approach for identifying coherent groups of generators in power systems based on the correlation coefficients between rotor angle oscillations of generators is presented. The method uses a newly proposed clustering index based on the correlation coefficients of generators oscillations which is able to classify any number of generators into coherent groups. The proposed approach uses real time data of generators oscillations via PMUs, so it is able to easily take into account the effect of system detailed modeling. Simulation results, obtained using MATLAB and DIgSILENT software on the Tehran power system show that the proposed algorithm is efficient and have a well performance regarding voltage and transient stability when solving the controlled islanding problem.
