摘要
选择有效的方案实现智能电网中的双向实时通信至关重要,电力线载波(PLC)技术提供了一种适合中国国情的低成本解决方案。介绍了OFDM PLC调制技术的优势,通过分析低压电力线通信信道输入阻抗,建立了低压电力线载波模块系统模型。并在关于电力线信道的研究基础上,设计了基于低压电力线的高速载波模块。测试结果表明,该载波模块设计方案具有较高的接收灵敏度和抗噪声能力。
Effective choice of the solution is essential to achieve a real-time, bi-directional（full- duplex） communication of the smart grid. The Power Line Carrier（PLC） technology provides a low-cost solution, which suits China＇s own national conditions. In this paper, the advantages of OFDM PLC modulation technology are introduced. A PLC module of system model is established through the analysis of the input impedance under the low-voltage power line channel. The high-speed PLC module based on low-voltage Power Line is also designed according to the studies of power line channel. The results show that the design of the PLC module has featured high receiving sensitivity and anti-noise ability.
