摘　　要：依据当前配电网技术发展的现状,针对配电网线损的理论计算,提出了一套整体的解决方案:基于GPRS的数据采集,并借助GPRS系统与Internet的互连,把终端数据传入企业局域网,有效地解决了FTU数据的传输途径;采用二叉树算法模型,计算模型上各节点的电流、电压及其下游线路的损耗;介绍了关于缺失数据处理的当前数学算法.基于该方案的线损分析系统,具有投资小、维护简单、计算结果准确的特点,它将对配电网的线损分析工程提供技术参考.According to the development situation of distribution network technology, aiming at the theory calculation of distribution network line loss,puts forward a suit of settlement project：on the basis of data acquisition by GPRS, with the help of interlinkage between GPRS system and Internet, introduces terminal datum into enterprise＇ s intranet. This project resolves data transmission approach of FTU effectively. Calculates the pressure, current of every node, and loss of downriver line by binary tree algorithm model. Introduces the current mathematic algorithm on missing data treatment. Line loss analysis system based on this project has some characteristics such as investment is small, maintenance is simple, calculation result is accurate, it will offer the technology reference for line loss analysis of distribution network.
