Anti drone solution for the power industry

1. Background of the plan

Cross provincial and cross regional transmission lines with a voltage of over 330 kV, as well as related substations and exchange stations, belong to national or regional level power dispatching agencies and are an important target.

In recent years, substations have done a lot of work in video surveillance, perimeter protection, personnel verification, and early warning linkage, and have achieved some results. However, in recent years, new security measures have mainly targeted ground facilities, and the airspace over XXX has not yet been protected, posing significant security risks.
. By adopting drone detection and drone navigation deception technology, an overall low altitude defense system is established to enhance the ability of substations to detect, prevent, and dispose of low altitude drones, in order to ensure the safety of low altitude airspace in sensitive areas.

2. Technical solution

According to the actual deployment on site, it is recommended to reduce the gain of detection and discovery equipment, narrow the detection radius, reduce the power of navigation signal transmission, minimize the impact on the surrounding environment, and ensure that the monitoring function can be achieved about 200m around the substation facilities.

2.2 Technical Proposal

The active defense system against unmanned aerial vehicles consists of fixed passive detection equipment, fixed omnidirectional navigation deception equipment, etc. The entire system data is transmitted to the command through fiber optics and 4G communication network. The system has manual and automatic operation functions:
In automatic operation mode, passive detection devices detect and identify drone signals, and automatically suppress and deceive GNSS (navigation signals); In manual operation mode, the satellite navigation deception device can be manually selected to turn on and off through remote control by management personnel, and the deception distance, deception mode, and deception direction (Yuxing series) can be set.
The main components of the system are as follows:
