Impact of a Surface Nuclear Blast on the Transient Stability of the Power System

In this chapter, we study the consequences of an improvised nuclear detonation (IND) to the sub-transmission and distribution systems of Washington D.C. in the Eastern Interconnection (EI). We briefly discuss the geographical location of the blast and the interconnection of the power utility serving this area, with the neighboring power utilities. Analysis of the grid with respect to steady state stability as well as transient stability is performed to understand the impact of loss in load as a result of the blast. The steady state analysis alone does not offer a complete understanding of the loss of the neighboring substations. The transient stability analysis shows that for the simulated event, the system stabilizes approximately 7 s after the occurrence of the event. The stability of the system can be attributed to the fact that the drop in load was relatively small compared to the generation capacity of the EI.
