基于现场总线技术的配电网自动化通信系统设计

Design of Distribution Network Automation Communication System Based on Field

阐述快速可靠的通信系统是配电网自动化系统实现远程监测与控制的关键。结合配电网通信系统的特点,对比RS-485总线现场通信模式,提出一种基于Lonworks网络技术的现场通信设计方案,该设计的开放性和实时性都优于RS-485方案,具有一定的实用价值。

Justifies that a fast and reliable communication system is the key for the distribution network automation system to realiz e remote monitoring and control,proposes a field communication design scheme based upon lonworks technique in the light of the characteristics of distribution network communication system and against RS-485bus field communication mode and points out that this scheme has better openness and real-timeness than RS-485scheme.
