Titel
HPEM vulnerability of substation control systems as components of the Smart Grid
Abstract
Nowadays, sectors like trade, mobility, health care or even public policy do highly depend on the power grid. Furthermore, there is a trend to move the electrical energy generation from central power plants towards spread out renewable energies. To manage their fluctuating production, the former demand-based control system has to be replaced by a supply-fitted consumption system. The additional electronics integrated into the power grid potentially raises its susceptibility to intentional electromagnetic interference (IEMI). Initial tests with the Smart Meter device category revealed a high susceptibility to High Power Electromagnetic (HPEM) interferences in the whole tested frequency range. In order to probe components more critical to grid stability, we are expanding our research to a higher hierarchical level - the substation control systems. These critical devices revealed a lower susceptibility than the Smart Meters, but the still occurring failures have a greater impact on the grid. The application of different test methods served the attempt to identify coupling paths into the configuration under test.
