HPEM Vulnerability of Smart Grid Substation Secondary Systems

Abstract

This paper presents the results of a test campaign with focus on identifying HPEM susceptibilities for eight different secondary systems used in smart grid substations as part of the SCADA (Supervisory Control and Data Acquisition) system. The devices were tested against conducted threats in a bulk current injection (BCI) setup and radiated threats inside a TEM waveguide. Testing multiple devices of each type from different manufacturers and generations is necessary to acquire a representative overview of typical HPEM (High Power Electromagnetics) susceptibility thresholds of such systems. The tests were performed at frequencies ranging from 10 MHz to 3400 MHz whereas the failure behaviour of the tested devices strongly depends on frequency, polarization of the electromagnetic (EM) field and device type.

Shielding Performance of Materials Under the Excitation of High-Intensity Transient Electromagnetic Pulse

“…In the past few years, great concern has been paid to the threat brought by high-intensity transient electromagnetic pulse, against the normal working of facilities such as electronic systems, networks, grids and communications [1]- [4], especially with the rapid development of pulsed power science and high-power microwave (HPM) technology [5]- [10]. Improving the survivability of facilities through taking protection and reinforcement measure is crucial for their normal use.…”
