摘要
智能电能表光通信模块的研究,在智能电网建设中发挥着重要作用。通过对EPON(以太网无源光网络)、PLC(电力载波通信)和WiMAX(全球微波互联接入)技术的对比分析,选择EPON作为智能电能表通信接入网技术,并设计了通信流程。基于QCA8829嵌入式芯片,在Redhat Linux 2.6.x开发平台上采用可接入EPON系统的光纤接口技术,实现了智能电能表主站与从站的通信系统。经测试表明,基于EPON智能电表光通信模块实现了智能电网配电侧信息全采集、全覆盖,并使远程电费控制及负载控制到户。
Optical communication modules for intelligent electric energy meters play an important role in the construction of smart grids. On the basis of the comparisons between and analysis of EPON, PLC, WiMAX technologies, EPON is selected as the communication access network technology for intelligent electric energy meters and the communication flow is designed. On the basis of QCA8829 embedded chips and the fiber-optic interface technology accessible to the EPON systems on the Redhat Linux 2.6. x development platform, the communication system from the master station to the slave station of intelligent energy meters is realized. Test results show that the proposed modules accomplish complete collection and full coverage of information at power distribution side of the smart grids and enable remote cost control and load control to the home.
