The invention provides a distribution network loss reduction method based on marketing and distribution
big data fusion and a terminal, and the method comprises the steps of: acquiring distribution network operation data, and building a
primary key relation between the data; constructing topology
logic structure data of the distribution network; fusing the distribution network operation data and the topological
logic structure data; respectively calculating user fine-grained loss and distribution network line fine-grained loss; optimizing the reactive power of the
power grid; and after the topological logic data of the distribution
network structure is established, according to the multi-
branch tree topology expression model of the distribution network line, realizing the
visualization of the data of the distribution
network structure according to the line hierarchy and the topological relationship between
branch lines, wires, towers and
distribution transformer users. According to the method, on the basis of fusion of distribution network
tower topology logic data and
distribution transformer operation data, a current and reactive superposition
algorithm is innovated, and distribution network
line loss fine-grained management and control and distribution network reactive power reduction optimization scheme recommendation are realized; and a
dynamic monitoring and early warning function of the operation condition of the distribution network is realized by using a structure
visualization technology.
