摘　　要：为解决现有低压配电台区采集终端过度、低效配置造成的台区智能化改造成本过高问题,提出一种面向低压配电台区拓扑结构采集的馈线终端(line terminal unit,LTU)优化配置方法。首先,为有效区分分支点、箱变、分支箱和各个进、出线开关,基于配电网零注入节点概念,构建低压配电台区零注入节点补充规则;其次,结合拓扑可观判据,以孤立点为搜索起始点位置,提出低压配电台区可观测树搜索法;然后,针对低压配电台区补充零注入节点导致低压配电台区采集终端配置不合理的问题,提出面向低压配电台区拓扑结构采集的LTU优化配置方法;最后,以山东某地低压配电台区验证了该方法的有效性。In order to solve the problem of excessive and inefficient allocation of acquisition terminals in the existing low-voltage distribution areas,which leads to high cost of intelligent transformation of the station areas,an optimization method for configuration of line terminal units(LTU)based on the topology of low-voltage distribution station areas is proposed.Firstly,in order to effectively distinguish the branch points,box transformers,branch boxes and the incoming and outcoming switches,based on the concept of zero injection node of distribution network,the supplementary rules of zero injection node in low-voltage distribution station areas are proposed.Secondly,combined with the topological observability criterion,taking the isolated point as the search starting point,the observable tree search method in the low-voltage distribution station area is proposed.Thirdly,to address the problem of unreasonable configuration of acquisition terminals in low-voltage distribution station areas caused by the addition of zero injection nodes,an optimization method for configuration of LTUs based on topology of low-voltage distribution station areas is proposed.Finally,a low-voltage distribution area in Shandong province is used to verify the effectiveness of the proposed method.
