摘要: 随着配电物联网的建设发展,低压台区数据的深度融合、低压配电网全景感知的精益化管理等深化应用在智能配电网的发展中已经必不可少。低压配电网拓扑网络结构是台区智能化应用的基础,而台区拓扑的自动生成一直是技术难点,为此提出一种以融合终端为核心,基于配电物联网的拓扑自动生成技术。首先,基于智能融合终端与用户高速电力线载波(high speed power line carrier,HPLC)智能电表的深度数据交流采集,充分利用智能电表采集的用户数据,形成用户特征信息集合,通过电压数据计算任意智能电表之间的相关性,判断其是否处于同一表箱。然后,通过数据集合中其余电气量数据,计算分支箱与智能电表之间最优解集,研判计算数据。最后,通过仿真算例和实际试点应用效果验证所提方法的可行性,并对未来拓扑生成技术的发展方向提出展望。Abstract: With the construction and development of the distribution Internet of Things,the deep integration between the lowvoltage station area data and the lean management requirements of low-voltage distribution network panoramic perception have become indispensable.The low-voltage distribution network topology network structure is the basis of intelligent application in station areas,and the automatic generation of the topology of the station area has always been a technical difficulty.A topology automatic generation technology with fusion terminal as the core based on the power distribution Internet of Things is proposed.Based on the deep data exchange between the smart fusion terminal and the user’s HPLC smart meter,we firstly make full use of the user data collected by the smart meter to form a user feature information set,and calculat the correlation between any smart meters through voltage data to determine whether it is Same table box.Secondly,through the remaining electrical data in the data set,we calculate the optimal solution set between the branch box and the smart meter,and judge the calculated data.Finally,we verify the feasibility of the proposed method by simulation examples and actual pilot application effects,and put forward some views on the development direction of future topology generation technology.
