【摘要】：在Q/GDW 1379.4-2013通信单元检验技术规范对载波通信单元功率消耗的限定要求下,为了有效提高低压电力集抄台区电能信息的采集速率,建设高速实时、双向智能的用电信息采集系统,提出了一种基于分子带的电力线载波速率最大化算法。以带宽2~30 MHz为信号载频,结合Homeplug AV规约下的子载波自适应调制方式,将相邻子载波进行逻辑分组为子带,以中值信噪比门限算法为基础,融入贪婪功率分配机制,合理分配分子带比特数,得到了最大化载波速率。仿真结果表明:较传统的信噪比门限算法和Homeplug AV自适应比特分配算法,提出的算法具有更高的载波速率,而相比于传统贪婪算法,虽达到的载波速率略低,却极大地降低了计算复杂度和硬件开销。
