Analysis of Radio Signal coverage of a feeder using Radio Mobile Software

Abstract

The study of propagation of signals by means of theoretical models in power distribution lines using computational tools has become important to forecast the propagation environment, as well as the identification of communication failures that decrease the signal coverage or block transmission completely, implying in the increase of service quality indicators penalties, and the average time of service, TMAE. Thus, an analysis was made of the propagation environment in the region of a feeder located in the state of Mato Grosso, from the choice of critical points and distant from the Substation. Initially, the objective was to identify possible shadow areas, considering the terrain profile in the feeder region and obstacles present in the path between transmitter and receiver. Computer simulations were performed with the parameters of radio and irradiating system using the Radio Mobile software. The objective of the study was to analyze the radio signal coverage of a feeder, verifying obstruction points and the impact of these in the communication and the attendance of the teams, considering aspects of feeder topology, road access and terrain conditions.
