摘　　要：针对低压电力线载波通信的复杂环境,本文提出并实现了一种计算机仿真系统,给出了动态模型和噪声的仿真算法,以及具体应用的示例。通过改变传输线、负载模拟电路的拓扑结构和参数,可以观察载波通信信号在不同信道阻抗特性、衰减特性和噪声特性下的工作情况,了解不同调制方式所引起的底层信号波形畸变和上层数据传输的可靠性,从而为电力线载波通信的产品设计提供依据。Considering the complex environment of power line carrier communication （PLCC）, this paper proposes and implements a computer simulating system, represents the simulation algorithm for dynamic model and noise, as well as an application example. Using this software, we can change the topological configuration and parameters of the line channel and the load circuits to observe the performance of carrier signal under different impedance, attenuation and noise characteristics, learn the wave distortion of signal and the reliability of data transmission. Finally provide a useful reference for PLCC product design.
