摘要
智能配电网的迅猛发展给电力载波技术带来巨大的挑战,传统协议标准如G3-PLC、PRIME、Home Plug、G.9960、IEEE P1901等标准已不能满足配电网的要求。文中以OFDM技术为依托,自主研发新一代电力载波装置。装置的带宽可在7.8 kHz至10 MHz之间灵活调整,装置收发前端和物理层处理单元在FPGA芯片中实现,MAC/汇聚层处理单元在ARM芯片中实现。数据进行通信时的信号功率衰减及信号失真率均符合有关标准的要求,测试结果验证了所研发装置实现数据传输的正确性和稳定性。
The rapid development of smart distribution has brought great challenges for power line carrier technology,while the traditional protocol standards can not meet the requirement of distribution network,such as G3-PLC,PRIME,HomePlug,G.9960,IEEE P1901and so on.A new generation device of power line carrier communication is designed independently with OPDM technology.The bandwidth of the device can be flexibly adjusted between7.8kHz to10MHz,and the processing units of physical and front-end are implemented in FPGA chip and MAC/convergence processing units work in ARM chip.Both attenuation of signals power and signal distortion rate accord with the requirement of the relevant standards,and test results verify that the research and developed device has a good stability and accuracy when it works.
