Abstract

The invention discloses a topology identification method and device for power distribution automation. The method comprises the following steps: in response to a received acquisition instruction, acquiring parameter information of each pulse transmitting node; analyzing the parameter information by using an edge algorithm to obtain a flow direction relationship among the pulse transmitting nodes;establishing a mathematical model corresponding to the flow direction relationship based on the charge space-time relationship; in response to a received topology check instruction, adopting the mathematical model to check the charge space relationship of all the pulse transmitting nodes in the topology identification result: if all the pulse transmitting nodes meet the requirements, determining that the topology identification result is successfully checked, and generating physical topology description information from the topology identification result and uploaded to a power distribution main station; if not all the topological recognition results meet the requirements, determining that the topological recognition results fail to be checked, and carrying out recognition again. Accordingto the invention, the technical problems of incomplete topological relation and disordered communication of the low-voltage distribution area in the distribution automation master station system in the prior art are solved.

Description

technical field [0001] The invention relates to the field of distribution automation, in particular to a topology recognition method and device for distribution automation. Background technique [0002] With the in-depth application of high-speed power line carrier communication technology in China, it is gradually found that the power line topology only realizes the logical topology function, and only grasps the central node and user node of the power network, and the connection relationship between the above nodes is unclear. At present, there are no automatic monitoring means for communication nodes such as transformers, meter boxes, Π junction boxes, and branch boxes in the low-voltage power distribution system. The identification of the physical topology of power lines relies heavily on manual on-site inspection, and there is a lack of effective means for topology analysis and verification identification. [0003] At present, the traditional low-voltage station area top...
