摘　　要：电力线宽带通信技术具有较多优势,但是低压电力线信道特性极为复杂,导致通信效果不能良好稳定。目前为止国际上尚未能形成统一的技术标准。我国的电力线信道特性也与国外不同,特别是早年对电网布线优化度重视不足及对电器质量要求较低,使得某些地区的信道条件相对恶劣。因此,低压电力线信道特性的合理检测和分析,对于我国电力线宽带通信标准的制定,调制解调器的研制及应用、电力线通信算法的仿真和改进来说,是非常有意义的。the power lines communication technology has lots of advantages, but Low voltage power lines communication channel characteristics is very complex, which can lead to unstable communication effect The reliability and research of communication about the power lines communication is still in the development, and all countries have different power grid environment. And so far people have not been able to form a unified international technical standard. China＇ s power line channel characteristic different from foreign and early to power wiring optimization degrees less attention to the appliance and low quality requirements, which make some areas relatively tough conditions channel. Therefore, we will be reasonable detection and analysis for power lines communication channel characteristics. It is very significant for our country make up standards, modem development and application, and benefit for power lines of communication algorithm simulation.
