非均匀传输特性的低压电力线载波传输模型

The Carrier Wave Communication Transmission Model of Low-Voltage Power Line Based on the Uneven Transmission Characteristics

在传统电力线均匀传输电路模型的基础上,结合电力线的非均匀传输特性,提出一种新的电力线载波通信的通信传输模型,该模型充分考虑了低压电力线阻抗特性、噪声干扰、衰减特性等因素对低压电力线载波通信的影响,从而为信号信道模型的建立提供了较好的理论依据。

Based on the even transmission line model and combined the uneven transmission characteristics of low-voltage power lines, a new transmission model of power lines is proposed. The model accounts for the influence of the unstable impedance characteristics, noise inference and signal decay of low-voltage power lines to the carrier communication of the lines. In this way, the proposed model provides theoretical basis for creating the signal channel model of the lines.
