在配电自动化系统中配电网监控是主要内容,而配电监控系统中关键问题是通信。传统的通讯手段包括电力载波、双绞线、光纤、专用无线电台等,它们都有自己的局限性。现在随着GSM、GPRS的通讯发展,基于无线公网和移动互联网的通讯方式得到了大家的关注,成为故障定位系统、抄表、配变监测等系统的通信通道的新选择。
In distribution automation system distribution network monitoring is the main content, and distribution monitoring system is the key issue of communication. The traditional means of communication include power line carrier, twisted pair, optical fiber, dedicated radio, etc., which have their own limitations. Now with the development of GSM and GPRS communications, communication based on wireless public network and mobile Internet has drawn everyone’s attention and become a new choice of communication channel for fault location system, meter reading and distribution transformer monitoring system.
