摘　　要：文章首次提出了类型扩展潮流计算,即扩展了常规潮流计算中节点类型。该算法不仅能够实现常规计算,而且可以获得一些特殊应用。文中给出类型扩展潮流计算的定义、迭代公式及修改主元的因子表分解方法,并将该方法应用于解决EMS/DTS一体化中数据范围不一致的问题,通过算例验证该算法的正确性。The extended-type load flow calculation, i.e., to extend the node types in conventional power flow calculation, is presented in this paper. The presented calculation method not only can be applied to conventional power flow calculations, but also can be used for some special applications. The definition of extended-type load flow calculation, its iterative formulae and the method of decomposing divisor table for pivot element modification are given. And this method is applied to solve the nonuniformity of data domain in EMS/DMS integration. The correctness of the presented algorithm is verified by calculation examples.
