Wireless Communications for Power Substations: RF Characterization and Modeling

How robust is a LoRa communication against impulsive noise?

“…The proposed study will not consider the fading issue but mainly focuses on noise, which can be very specific in such a context. As introduced in [10], [11], the noise is indeed more impulsive than Gaussian, leading to a degradation of performance in terms of reliability and energy consumption.…”

“…It was shown in previous works [10], [11], [15], [23] that impulsive noise modeled with Middleton distribution has an important impact when the receiver was designed with the assumption of Gaussian noise. A typical behavior of the SER is the presence of a flat part leading to a significant SNR loss.…”

“…This can lead to a performance degradation of the wireless link and impact the energy consumption and the reliability, crucial to the FoF. For example, a high voltage substation uses a lot of power devices and the monitoring is disturbed with an impulsive noise modeled with a Middleton distribution [10], [11]. In order to efficiently deploy wireless sensor nodes in factories, there is a crucial need for fast and accurate performance estimation of IoT technologies in this particular context.…”

Radiometric localisation of partial discharge sources inside Air‐insulated electrical substation

“…PD occurrence in the power system equipment generates the pulsating high-frequency electrical signal. That is because PD brings about electron transfer in a short duration, within nanoseconds [5], which further create visible, invisible, Infrared and ultraviolet (UV) light (100-400 nm), radio frequency (300-3000 MHz) [4], and even ionising radiation of higher energies such as X-ray [6], which has frequency higher than UV. The authors in [6], have applied X-ray dosimeter for the detection of PD generated in polymeric cable insulation.…”

“…Different types of sensors have been tested for capturing the EM wave from PD sources [15] occurring in substation equipment. Propagation of EM waves its attenuations in different mediums, detection of PD signals using different types of antenna, its recording and its influence by other factors can be found in [5,16].…”
