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.
