电力通信系统的宽带调节技术

当前利用分层网络结构对电力通信系统数字信道进行调节的方式,存在吞吐量性能差、宽带分配不均衡以及电力信息传输丢失严重等问题。提出利用遗传算法对电力通信系统宽带进行调节。对电力通信系统宽带中,每个OFDM符号内多个用户同时进行电力数据传输中的多种参数进行定义并计算,对最大的传输比特数以及最大功率进行计算,在电力通信资源分配速率的自适应和功率自适应的目标几乎一致理论基础上,建立电力通信多用户速率自适应宽带资源分配的数学模型,针对多用户的多目标特点,利用遗传算法中优良基因的注入,跨世代精英的保留以及迭代次数等,满足电力通信系统的多用户宽带资源分配需求。并通过实验证明,所提方法可实现电力通信系统宽带的有效调节。

Broadband regulation technology of power communication system

The current use of hierarchical network structure of electric power communication system adjusted to the digital channel,and there are some problems,such aspoor throughput performance,unbalanced broud band distribution and serious loss of power informetion transmission.To this end,it is proposed to use genetic algorithm to adjust the broadband of power communication system.In the electric power broadband communication system,multiple users simultaneously in each OFDM symbol power data transmission in a variety of parameters are defined and calculated,then the maximum transmission bits and the maximum power are calculated.Based on the theory of almost cosistenas electric power communication resource allocation rate adaptive and power adaptive goal, mathematical model of resource allocation for electric power communication more user rate adaptive broadband.Finally,according to the characteristics of multi-user multi-objective,good genes of the genetic algorithm is used to inject,retention and the number of iterations of the generational elite is used to meet the multi-user broadband resource allocation in electric power communication system requirements.It is proved by experiment that the proposed method can effectively adjust the broadband of power communication system.
