摘　　要： 结合配电自动化的工程实际问题,针对很多配电系统只装设馈线终端单元(FTU)而欠缺配变终端单元(TTU)的情况,提出了一种基于地理信息系统(GIS)和区间FTU的配电网网损计算方法。该方法利用馈线区间FTU的量测数据和负荷容量,把原来基于馈线的网损计算改进为按区间进行计算的算法,既克服了TTU装设不完全的问题,又提高了计算精度和对各类网损的分析管理能力。文中还提出了一种基于GIS的区间拓扑分析方法,使拓扑分析与网损计算具有相对的独立性,程序结构更清晰,并具有对不完整量测数据的处理能力。 Combined with engineering practices of DAS and considering the situation that in many distribution networks onlyFTUs are configured, but not the TTUs, a new GIS and sectional FTU based calculation method for transmission losses indistribution networks is put forward in which by use of the load capacity and the measured data of FTU the network loss calculation originally based on the feeders is changed into that based onsections. This method not only can remedy the shortcoming of the insufficient number of TTUs, but also can improve the calculation accuracy and the ability of managing and analyzing various kinds of network losses. Meanwhile, a sectional topological analyzingmethod based on GIS is put forward which makes topological analysis and network loss calculation relatively independent and the structure of program clearer. The presented method can also process incomplete measured data.
