Abstract

The invention relates to a special topology analysis method for a distribution network. The method comprises the following steps of: providing distribution network circuit diagrams; obtaining all the geographic information of circuits and equipment according to the circuit diagrams so as to establish a topology connection relation between the equipment and the circuits; establishing a topology table according to the topology connection relation between the equipment and the circuits; and analyzing the topology table. The invention has the advantages that different objects in the same layer can be represented by setting special graphic symbols according to the requirement of a user, then a topology layer is added on all diagram layers to ensure that the user cannot feel the existence of the topology, thus the method can realize the functions of real-time topology connection and disconnection, and the states of affected equipment can be changed in real time according to the topology states of the equipment. The method and the device disclosed by the invention can be used for accurately and reliably realizing the topology analysis function of the distribution network in real time andalso for conveniently realizing the applications of power cut simulation, power supply range, power supply tracking, and the like.

Description

【Technical field】 [0001] The invention relates to the technical field of power grid control, in particular to a topology analysis method and device specially used for distribution networks. 【Background technique】 [0002] The existing distribution geographic management information system does not have a topology analysis module dedicated to the distribution network, but uses a general topology analysis module. This general module cannot clearly specify the topological relationship according to the connection relationship between distribution network equipment, so The exact line of device connection cannot be guaranteed, and repeated search paths in the work lead to low efficiency and slow speed. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to provide a topology analysis method and its device dedicated to the distribution network, so as to improve the accuracy and efficiency of equipment analysis. [0004] In order to solve...
