摘　　要：针对目前配电网自动化设备的覆盖率较低、配电网模型数据维护量大、基础数据不完整、研究实时量测信息缺少情况,结合用电信息采集和典型负荷特性进行负荷校验和负荷补全。利用最优乘子法,结合配电网辐射网络结构,采取分块稀疏矩阵技术,既保证了潮流计算收敛,又保证了计算快速准确性,满足了实际工程的需要,从而解决实际工程中的实用化潮流分析计算问题。The low rate of using automation equipment, big amount of distribution network model data, incompletion of fundamental data and lacking of real-time measured information, a method for load verification and information completing based on electricity data collecting and load characteristic analysis is proposed. By using optimal multiplier method, combining radial distribution network structure and adopting block sparse matrix technology, the proposed method ensures the convergence, fast speed and accuracy of power flow calculation, which satisfies the engineering requirement and can be used in practical engineering projects.
