The electromagnetic environment in the substation is complex, and the communication system needs to have a strong anti-interference ability to ensure normal operation; in addition, the substation communication system has high requirements for communication quality, and certain quantities are not allowed to make mistakes during the communication process. Ensuring high accuracy is an important indicator of whether the communication system can meet the conditions.

Inside the substation, the operating environment of communication equipment is very harsh. In addition to the influence of mechanical vibration and temperature and humidity, electromagnetic interference is very serious. In such an operating environment, wireless sensor nodes need to have good resistance to mechanical shock and vibration, temperature and humidity changes, and must have good anti-electromagnetic interference performance, so that they can reliably complete the established functions, otherwise it may cause damage to the wireless sensor. Nodes fail, or even send or receive wrong data or instructions, resulting in losses.

Typical sources of electromagnetic interference in substations include: 50Hz power frequency electromagnetic field, pulsed magnetic field caused by equipment outlet short circuit, corona discharge, electrostatic discharge, partial discharge, air breakdown arcing, SF6 gap breakdown arcing, vacuum gap breakdown Wear arcing, lightning waves and operating overvoltage. Among them, 50Hz power frequency electromagnetic field, pulsed magnetic field caused by short circuit at the equipment outlet, corona discharge, electrostatic discharge, partial discharge, air breakdown and arcing, these interference sources are of low frequency (up to about 800MHz) and the signal strength of each low frequency band is low. Large, it will not have a significant impact on the wireless sensor network communication itself working at 2.4GHz.
