基于EPON技术的智能配电通信系统的设计

落后的配电网通信制约智能电网发展，EPON技术是实现高速实时可靠配电网通信的支撑。本文通过比较目前配电网采用的几种通信方式，提出了EPON组网应用于智能配电通信系统的具体方案，针对EPON组网的安全管理问题，对ONU的端口管理策略、VLAN隔离方式进行设计，为EPON应用于智能配电通信系统打下理论基础。

Design of Smart Communication System of Power Distribution Based on EPON Technology

The poor distribution network communication restricts the development of smart grid. EPON technology is the support to achieve high-speed, real-time, reliable distribution network communication. This paper puts forward a solution to apply EPON network to smart distribution communication system, which is compared with the several communication means of current distribution network. Aiming at the security management issues of EPON network, the port management policy of ONU and the isolation mode of VLAN are designed, to provide a theoretical basis for EPON applied to smart distribution communica- tion system.
