摘　　要：提出一种配电网理论线损实时计算分析系统,包括主站系统、10 k V馈线保护测控装置、馈线终端、智能配变终端和通信通道。该系统根据配电线路上各监测点上传的配电网实时运行数据和开关状态,结合线路参数,利用前推回代潮流算法进行配电网理论线损的在线计算。该系统可提高线损计算的准确度和时效性,按馈线区段给出线损的实时分布情况,便于掌握线损在系统中的分布规律,分析其成因,为降损技术措施的制定提供依据。A real-time calculation and analysis system tor theo- retical loss calculation of distribution network is proposed, which in- cludes master station system, protection and control device of 10 kV feeder, FTU, IDTT and communication channel. According to the real- time operating data and switch states uploaded by each monitoring point in distribution lines, combining the line parameters, the hack/ forward sweep method is utilized to on-line calculate the theoretical loss of distribution network. And the design scheme of IDTT is main- ly introduced. This system can improve the accuracy and timeliness of loss calculation, and provide the real-time loss distribution of every feeder zone. Thus it is convenient to master the loss distribution law in the whole network and analyze the reason of the loss generation, in order to tormulate proper technical means to decrease line loss.
