Abstract:
In the field communication network of transmission and distribution
lines, micro-power wireless communication technology needs to solve the
adaptability problem brought by long-distance transmission, and also needs to support the time synchronization of power information processing. In this
paper, the technical scheme of the construction of the field communication
network by the micro-power wireless transmission technology represented
by IEEE802.11g (2.4GHz) is discussed. The theoretical analysis and computer
simulation of the communication throughput and delay under the point-to-point
networking topology are carried out, and the relationship between the distance
communication and the delay and throughput is tested. Based on the analysis
data, the adaptability of micro power wireless communication technology to the
communication technology index defined by IEEE2030 standard is obtained.
Aiming at the demand of power information service synchronization, the micro
power wireless synchronization technology in the field network is proposed,
and the performance of the proposed synchronization algorithm is analyzed
and simulated.
