Abstract
Control devices such as inverters and generator controllers are critical for the stable operation of the power grid, especially for power stability control and power dispatch. However, the Electromagnetic Pulse (EMP) is a potential threat to electronic devices in modern power grids, therefore decreasing the power grid resilience and bringing unrecoverable damages to the devices. To reveal the impact mechanism of the EMP, impedance and Pulse Current Injection (PCI) testing is established to study the vulnerability of the grid control devices. The impedance of the grid control devices is accurately measured using impedance analyzers with different frequency ranges. Then the voltage and current responses are tested based on the PCI testing. The vulnerability experiments based on two grid control devices are carried out. And the comparison results reveal that most ports would be damaged under EC8, and some ports can survive under EC5 according to the calculated PCI response and cumulative energy. The results can provide a reference for the future design of control devices and the strategic resilience of power grids.
