Analysis and Experimental Validation of Electromagnetic Interference of Anti-UAV Equipment on Time Synchronization Devices in Electrical Substations

Abstract

Considering the rapid development of the unmanned aerial vehicle (UAV) industry, it is crucial to prevent UAVs from accidentally entering substations. Installation of anti-UAV equipment is the most effective way to address this issue. However, the influence of electromagnetic interference (EMI) signals emitted by anti-UAV equipment on time synchronization devices (TSDs) used in substations has not been investigated in detail. This paper proposes an EMI evaluation method for the effect of anti-UAV equipment on TSDs. Simulations and Experiments were conducted to validate the proposed method with the results indicating that deceptive anti-UAV equipment (DAE) is more suitable for substations than suppressive anti-UAV equipment (SAE). Moreover, it is established that DAE should be installed 60 m away from TSDs in substations. This recommendation offers valuable guidance for the installation and deployment of anti-UAV equipment in substations in the future.
