随着通信技术的发展和光纤、卫星通信在电力通信网中的大量应用,电力线载波通信逐步由电力系统通信的主要通信方式改变为不可或缺的备用通信方式。在目前电力线载波频率资源相对不太紧张的条件下,应用最新的通信技术以革新传统的电力线载波通信是一个必然趋势。文中提出了一种基于FPGA的占全可用频段的高压输电线载波高速数字通信方案和设计,相对于传统电力线载波通信其显著优势在于具有高速的用户速率和丰富的数字接口。最后文中分析了高速输电线PLC设备的广泛应用前景。
With the development of communication technology and the large number of applications of optical fiber and satellite communication in power communication network, power line carrier communication is gradually changed from the main communication mode of power system communication to an indispensable backup communication mode. Under the condition that the power line carrier frequency resource is relatively not so tight at present, it is an inevitable trend to apply the latest communication technology to reform the traditional power line carrier communication. In this paper, a high-speed digital communication scheme and design of high-voltage power line carrier based on FPGA is presented. Compared with the traditional power line carrier communication, it has the significant advantages of high-speed user rate and rich digital interface. Finally, the article analyzes the wide application prospect of high speed transmission line PLC equipment.
