一种基于FT3编码的新型配电网通信方法

Novel Communication Method for Distribution Network Based on FT3 Coding

针对配电系统中一次设备与二次终端之间接线复杂,易受干扰等问题,提出一种基于FT3编码的一二次设备光纤通信设计方案,以FPGA和MK64微处理器构建的架构作为核心,利用硬件、软件相结合的方式,对光纤通信系统进行了设计。该设计方案以数字信号传输代替传统模拟量传输,使用光纤代替航插连接,通信速度快,抗干扰性强,提升了系统的开放水平及一二次融合的数字化水平。

Aiming at the problems of complex wiring and easy interference between primary equipment and secondary terminals in distribution system,an optical fiber communication design scheme of primary and secondary equipment based on FT3 coding is proposed.Taking the architecture of FPGA and mk64 microprocessor as the core,the optical fiber communication system is designed by combining hardware and software.The design scheme replaces the traditional analog transmission with digital signal transmission and uses optical fiber instead of aerial plug-in connection.It has fast communication speed and strong anti-interference,and improves the openness of the system and the digital level of primary and secondary fusion.
