An Experimental Characterization of Substation Impulsive Noise for a RF Channel Model

摘要

Deploying wireless communication system, wireless sensors networks, for example, in a substation is problematic due to electromagnetic (EM) noise. The latter is partial discharges from high voltage (HV) equipments, electrical arcs from circuit breakers, etc. This paper deals with EM noise emitted by partial discharges (PD). PD pulses are highly impulsive and occur when the applied voltage is sufficient high. Our research work is to define metrics and methodology for electromagnetic noise characterization. This approach gives substantial information about RF channel in substations environments in which impulsive noise are omnipresent. This information will be useful for accurate channel modelling to ensure high quality in the transmitted signal.
