The application discloses a kind of leakage point positioning method, equipment and medium of water supply network, belong to water supply network operation and leakage control technical field, for solving in existing leakage point positioning, it is easy to rely on single data, equipment and algorithm complex, and also lack high-precision space linkage and to data adaptability and insufficient refinement, it is difficult to realize the technical problems of accurate positioning of water leakage point of water supply network.Method includes: the operating state of water supply network is processed to multi-source data acquisition, obtains water supply network core data;The standardization processing of feature vector is carried out to the corrected water supply network core data after pre-processing, obtains effective water supply network data;Effective water supply network data is screened under the risk value of leakage point area about leakage point, obtains high suspected leakage point area based on water supply network section;Leakage point spatial positioning calculation is carried out to high suspected leakage point area under local topology, obtains the final leakage point area position in water supply network grid.
