摘要:
为解决目前先进计量系统无法提供对智能电网中所有仪表进行同步和公平访问的问题,提出了一种基于正交频分多址接入技术的交互式通信模型,实现低压电力线通信系统优化。采用自适应比特加载技术和低密度奇偶校验编码技术,构建了时变、可选择频率的电力网信道模型,在此基础上开发了收发器。仿真实验表明在10-3误码率的条件下,收发器可提供智能电网中上位机到多电表之间的同时公平访问,每个仪表的总体有效功率约为1 Mbps,并可根据电网结构的特征优化通道模型。
Abstract:
To solve the problem that the existing advanced metering infrastructure can not access synchronously and fairly for all meters in smart grids,an interaction communication model based on orthogonal frequency division multiple access is proposed to realize a communication system optimized for the low voltage power lines.A time-varying and selectable frequency power grid channel model is constructed using adaptive bit-loading and low density parity check coding technique and a transceiver is developed based on this model.The simulation experiments show under the conditions of 10-3 bit error rate,the transceiver provides a fair access from the head end to multiple meters in smart grids synchronously,the overall effective power of each instrument is about 1 Mbps,and the channel model can be optimized based on the characteristics of the grid structure.
