电力线载波通信技术的发展及特点

Development and Characteristics of Power Line Carrier Communication Technology

目前,我国的电力通信网已成为电力系统安全稳定的保障,能实现电网调度自动化、网络运营稳定化以及管理现代化。电力线载波通信可根据电压等级划分为高压、中低压以及低压。其中,高压载波通道比较单一,技术也很成熟;中低压通常属于民用;低压电力线载波通道使用的用户基数很大,网络结构相对复杂,研究相对困难。鉴于此,探讨我国目前电力线载波通信技术的发展现状和电力线载波通信的特点,并研究低压电力载波通信技术在智能电网调度中的应用。

At present,China’s power communication network has become the guarantee of the security and stability of the power system,which can realize the automation of power grid dispatch,network operation stabilization and management modernization.Power line carrier communication can be divided into high voltage,middle and low voltage according to the voltage level.The high voltage carrier channel is relatively single,and the technology is very mature.Low and medium voltage are usually for civil use,while the low voltage power line carrier channel USES a large user base,and the network structure is relatively complex,so it is relatively difficult to study.In this paper,the development of power line carrier communication technology and the characteristics of power line carrier communication in China are discussed,and the application of low-voltage power carrier communication technology in smart grid dispatching is studied.
