Abstract:

A rural electrical cooperative system is analyzed for EMP vulnerability. The coupling to a particular substation within the system is determined by considering the power distribution lines as antennas which pick up the incident EMP and treats the substation as a load. The most vulnerable components within the substation are determined and the energy levels necessary for failure are calculated. From the coupling problem the energy levels at various locations within the substation are known and the coupling to the vulnerable ports are determined. A ratio of coupled to threshold values is calculated and if the ratio is above 1, failure is assumed, and if below 1, no failure is assumed. If failure is indicated the reasons are determined so as to recommend hardening techniques. Although the detailed analysis is performed on one particular substation, the results may be compared to other similar systems throughout the country and perhaps knowledge of their response to an EMP may be gained from this analysis.
