摘要
提出了一种基于V.34协议和DSP芯片的全数字中压配电线载波机的设计方案。该方案针对中压电力线信道高衰弱、强干扰的特性,分别加入了RS编码和交织技术来抵消突发噪声的干扰,加入了自适应功率控制(APC)和自适应增益控制(AGC)来抵消高衰弱。这些技术保证了载波机能够在4 kHz载波频带内达到33.6 kbit/s的通信速率。设计完成后,在Matlab和CCS开发环境以及硬件板上做了大量的仿真和分析工作,结果显示其功能和实时性均达到了较高的水平。该方案拥有自主的核心算法,可以针对具体的应用制定灵活的实现方案,因此具有广阔的市场应用前景。
This paper proposes a scheme of digital Medium-Voltage（MV） power line communication system based on V. 34 protocol and Digital Signal Processing （DSP） chip. Considering the high debility and strong interfere from MV power lines, Reed-Solomon （RS） and interlaced codes are adopted to resist interference of outburst noise. At same time automatic Power Control （APC） and Automatic Gain Control （AGC） are added to eliminate high debility. By using these technologies, communication rate of 33.6 kbit/ s in a single 4 kHz bandwidth can he achieved. Simulation and analysis have been made by using Matlah, CCS and hardware circuit boards. The results show that its functions and real-time performance have reached a high level. Since it owns the core algorithm, a flexible implementation can be applied to different application. So this scheme will have a bright future.
