高速中高压网络载波通信机的设计和实现

Design and implementation of high- speed network-type power line carrier in medium and high voltage power grid

目前的中高压电力线载波通信的传输速率都很低,只能应用于低速的场合,用户容量有限.采用数字信号处理技术、计算机网络技术、数字通信技术及嵌入式系统技术等,提出了高速中高压电力线数字网络载波通信机的设计方案,该载波通信机在40～500 kHz的带宽内的传输速率可达几百kbit/s,对不同的传输业务具有很高的服务质量,解决了在电力线上进行可靠、快速、网络化的数据传输问题.

At present, transmitting speed of medium and high voltage power line carrier is very low, and these kinds of carriers can be used only in low speed situation, and the number of user is limited. Adopting digital signal processing technology, computer network technology, digital communication technology, embedded system technology and so on, a design scheme of high speed network type power line carrier used on medium and high voltage power grid is proposed in this paper. The speed of the carrier can be up to several hundreds kbit/s in 40~500 kHz bandwidth and this kind of carrier has good quality of services (QoS) to meet the needs of data transmitting in reliability, high speed and the mode of network.
