Embodiment 1

[0027] (1) After receiving 4 fault reports from users within a certain period of time, click the fault location button to display the fault point on the GIS map;

[0028] (2) Select the current repair information, press the button for failure research and judgment, trace the highest voltage level of AC 10KV through the power supply point, and get the power supply path for the repair report: low-voltage user access point-on-pole fuse box-10KV on-pole transformer;

[0029] (3) Click on the electrical equipment on the power supply path to analyze the real-time repair information, and mark it on the GIS map at the same time. Finally, it is found that the 4 fault repairs are completely within the 10KV column transformer and within the scope of the power supply, so they are preliminarily judged as fault points , at this time, the current 4 repair orders can be merged;

[0030] (4) Select the 10KV pole-mounted transformer and click the Affected Users View button to analyze the pole d...

Abstract

The invention discloses a power distribution network fault emergency maintenance method based on topology analysis. The method comprises the steps of 1, receiving a repair form from a power distribution network user, and ensuring that the information of the user is related to a user access point and electrical equipment; 2, calculating whether the user is a medium-voltage user or low-voltage user and the serial number of the electrical equipment according to the user ID, and analyzing the power supply path of the user automatically to form a power outage affected user set; 3, displaying all related electrical equipment from a power supply point to power users in a located mode based on the visual displaying function of a power grid GIS, so that quick positioning of a fault point is achieved by means of the power grid GIS; 4, conducting correlation analysis on an outage event through fault assist study and judge and determining the electrical equipment with the fault point; 5, calculating the optimal emergency maintenance team which provides a dispatcher according to the position of the determined electrical equipment with the fault point and a scheduling rule. By the adoption of the method, emergency maintenance resource scheduling efficiency and reasonability are improved, fault emergency maintenance efficiency is improved, and application prospects are broad.

Description

technical field [0001] The invention relates to a fault repair method for a distribution network based on topology analysis, and belongs to the technical field of distribution network fault analysis. Background technique [0002] In the research of power grid repair fault analysis, repair merge and fault location, emergency repair resource scheduling and emergency repair path analysis for distribution network user repair, the establishment of emergency repair single fault analysis and location model is the key to ensure fast and efficient distribution network fault repair , Power GIS (Geographic Information System) is a technology that applies GIS technology to the field of electric power industry. Connect to form a comprehensive information system of electric power informatization, and provide information on electric power equipment and facilities, power grid operation status information, electric power technology information, production and operation information, electric ...
