面向低压配电台区拓扑结构采集的馈线终端优化配置方法
An Optimization Method for Configuration of Line Terminal Units Based on Topology-Based Data Collection in Low-Voltage Distribution Areas
摘要
Abstract
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.关键词
