摘要
结合低压电力线载波通信传输特性的分析,设计了包含净化电源、载波信号源、噪声信号源、负载网络等部分的低压电力线载波通信模拟实验系统.给出了各部分的硬件电路图或原理图.该系统可通过改变电网模拟环境的给定参量,如载波信号波形、噪声信号波形、负载拓扑、负载值来模拟电网在不同地区、不同时段、不同负载、不同干扰情况下的传输环境.从而为研究低压电力线载波通信技术提供了一个良好的实验平台.
To describe the design plan of hardware of PLC simulating experiment system which includes purify electrical source, carrier wave signal source, noise signal source, load network combined with the transmit character of PLC, and presenting hardware circuit diagram of each parts. This system could simulate various kinds of actual environments of power network such as different areas, time interval, interruptions, loads. As a result, it will provide a good environment panel for research of PLC technology.
