低压台区配电变压器低压侧三相电压较低不平衡度及空房和轻载用户的存在导致利用单一电气量测量数据难以实现相户关系的精准识别。文中提出了一种综合电压电流监测数据的低压台区相户关系两步识别方法。首先,提取用户电压监测数据趋势转折点,定义并使用共有趋势转折点集合对原电压序列进行筛
选与排列,之后计算相似度矩阵,结合
k
-means聚类划分出用户集群。其次,采用LASSO回归算法计算相户关系回归系数矩阵,获得最优相户关系匹配结果,实现低压台区相户关系的精准识别。最后,通过实际算例分析验证了所提算法的有效性和先进性。
The low three-phase voltage imbalance on the low-voltage side of distribution transformers in low-voltage distribution station areas and the presence of vacant households and light-load customers make it difficult to achieve accurate identification of phase-customer relationship using single electrical measurement data. This paper proposes a two-step identification method for phase-customer relationship in low-voltage distribution station areas by integrating voltage and current monitoring data. Firstly
trend turning points are extracted from customer voltage monitoring data. A common trend transition point set is defined and used to filter and arrange the original voltage sequences
followed by similarity matrix calculation and
k
-means clustering to partition user clusters. Secondly
the LASSO regression algorithm is employed to compute the regression coefficient matrix for the phase-customer relationship
thereby obtaining the optimal phase-customer relationship matching results and achieving accurate identification of phase-customer relationships in low-voltage distribution station areas. Finally
the effectiveness and superiority of the proposed algorithm are validated through actual case study analysis.
