The invention provides a node Newton line loss calculation method based on data partition, and relates to the field of load flow line loss calculation. The method comprises the following steps: preprocessing power grid data, and calculating line loss of any partition by a node Newton method. According to the method, power grid nodes are classified according to the type of power grid data to obtain complete line power data, then a boundary equivalence principle of power grid division is established, and division of any region of a power grid is realized. On the basis of power grid partition division, the network loss of each sub-grid is calculated through the node Newton method, and the flexibility of intelligent power grid line loss management and the correctness of line loss calculation are greatly improved. 本发明提供一种基于数据分区的节点牛顿计算线损方法，涉及潮流计算线损领域。该方法包括以下步骤：电网数据的预处理、节点牛顿法计算任意分区线损。该方法根据电网数据的类型对电网节点进行分类，得到完整的线路功率数据，然后建立电网划分的边界等价原则，实现电网的任意区域划分。在电网分区划分的基础上，再通过节点牛顿法计算各子网的网损，大大提高了智能电网线损管理的灵活性与线损计算的正确性。
