摘　　要：随着自动化电力集中抄表系统不断应用,基于GPRS无线通信两类集中抄表系统得到广泛应用。并借用采用低压电力载波技术的"用户台区归属"识别仪,来区分不同台区交界边缘计量电表的变压器归属问题;确保正确计算变压器台区线损,和按正确范围发放停电通知等工作。但在实际应用中普遍反映此类仪器载波通信不稳定、效率低,识别能力弱,无法真正达到实用化程度。通过实践测试、分析,总结出一种通过改进识别仪装接工艺,提高低压电力载波通信效率的方法。With the application of automation power centralized meter reading system, centralized meter reading system which based on GPRS and wireless communication technology is wildly used. With the help of user＇s switch house reor- ganization instrument which used the technology of low-voltage power line carrier, it can work out the problem of identify transformer of border edge measuring instrument from different switch houses;make sure figure out the line loss at trans- formers in the switch houses, and do the work as sending outage notices to the right areas. But in piratical application, it is generally reported that that kind of instrument has the problems such unstable communication, inefficiency, poor reor- ganization, and far away from actualization. After the author testing practice, analyzing, the author sums up a method which can improve the efficiency of low-voltage power line carrier communication by improving loading joint technology of recognition instrument.
