Wireless Communications for Power Substations: RF Characterization and Modeling

The book "Wireless Communications for Power Substations: RF Characterization and Modeling" offers a comprehensive analysis of electromagnetic interference in substations, which is crucial for the implementation of wireless sensor networks. The authors provide a detailed description of the measurement setup used to capture impulsive noise samples in the relevant ISM band. This setup allows for the broadband measurement of impulsive noises in substations and the collection of sufficiently precise data for statistical analyses. During a measurement campaign, approximately 120 noise sequences were recorded in various substations across four voltage levels (25 kV, 230 kV, 315 kV, and 735 kV). The book proposes a characterization process that enables the measurement of physical characteristics of partial discharges using statistical methods. Additionally, chapters 4 and 5 explore the modeling of electromagnetic disturbances caused by partial discharge sources and present a coherent model that links the physical properties of high-voltage installations with the induced radio interference spectra.
