智能电网的电力光纤入户技术及其应用

Application of PFTTH technology in smart grid

介绍了电力光纤入户技术的实现目标和以太无源光网络(EPON)的网络结构。给出了电力光纤到楼的2种通信建设方案:一种是集中器与主站通信的远程信道采用光纤通信,本地信道使用低压电力线载波、RS-485、短距离无线通信的方式;另一种是光纤采集器与主站经光纤网络直接通信的方式。提出一种电力光纤入户系统的通信建设方案,即采用光纤电能表与主站经光纤网络直接通信的方式。根据上述建设方案进行了合理的设备配置,以某大楼为例详细说明了电力光纤入户技术设计方案。最后,介绍了南桥智能小区试点的电力光纤入户技术。

The implementation objective of PFTFH（Power Fiber To The Home） technology and the structure of EPON（Ethernet Passive Optical Network） are introduced. Two communication construction schemes of PFTTB（Power Fiber To The Building） are given. The first one adopts optical fiber communication for the remote channel between concentrator and master station and low-voltage power line carrier,RS-485 and short distance wireless communication for the local channels. The other one adopts the direct communication between fiber collector and master station via optic-fiber network. A communication construction scheme of PFTI＇H is proposed,which adopts the direct communication between optic-fiber power meter and main station via optic-fiber network. Equipments are rationally configured for these schemes,which are explained in detail with an example. The pilot project,application of PFTTH technology to Nanqiao smart community,is introduced.
