基于GPRS配电网自动化通信系统终端的设计与工程实现

针对配电网自动化通信系统对数据传输可靠性和实时性等要求，指出无线通信以其方便、快捷和廉价的优势可弥补传统配电网自动化系统通信方式的不足。提出一种基于通用分组无线业务GPRS(General Packed Radio Service)的配电网自动化通信系统设计方案。在简要介绍配电网系统整体结构、工作原理、主要特点的基础上，详细论述系统的核心部分——GPRS数据通信模块的设计与工程实现。设计的系统已投入电表集抄的实际应用中；实践表明具有实时性强、传输速率快、数据吞吐量大、可靠等特点。

Design and implementation of communication system terminal based on GPRS technology for distribution network automation

According to the requirements of distribution network automation communication system for reliability and real-time performance,the wireless communication,which is convenient,rapid and low-cost,can make up for the shortages of traditional communication mode of distribution network automation system. A new distribution network automation communication system based on GPRS(General Packed Radio Service) is presented. Its structure,operational principle and main features are introduced briefly and the design and implementation of GPRS data communication module,which is the core of the system,are detailed. The proposed system has been put into operation in an automatic meter reading system. Experiments show that the system is characterized by its real-time performance,high speed,great data throughput,high reliability and so on.
