Abstract

Abstract: The relative positions of electrical equipment and metallic character affect the communication performance of radio frequency identification monitoring system for substation. Considering the tunnel-like environment and metallic media in substation, a RFID(Radio Frequency Identification) tag-sensor monitoring system for electrical equipment in substation based on multi-antennas is proposed. The channel model of monitoring system is built and the performance influence factors are analyzed. The results reveal that, when the distance from the reader antennas to the tag-sensor d is less than 80m, the bit error rate of four-antennas system can be reduced one to three orders of magnitude than that of two-antennas and single-antenna systems. When 25 m < d <80 m, the bit error rate of antennas vertically placed mode is reduced from 20% to 40% than that of horizontally placed mode.

Key words: electromagnetic propagation, multi-antenna RFID monitoring system, the channel model, performance analysis
