摘　　要：针对低压电力线通信环境复杂的特点,本文在综述信道模型的基础上,根据对其阻抗特性、衰减特性及噪声特性的分析,提出并实现了利用实际网络结构、负载装置和电力线模拟电路,组成信道模拟系统的方法.通过对其传输特性进行测试,阐明了其用于模拟低压电力线通信环境的作用.Considering the complex environment of PLCC, this paper first establishes the channel model ot lowvoltage power line on the basis of the research of its impedance, attenuation, and noise characteristics. This paper proposes and implements a method for designing channel simulation equipment using the real network configuration, load and simulation circuits. Further, the transmission characteristics of the equipment are tested and its function for simulating the low-voltage power line communication is illustrated.
