Power failure analysis method based on single line diagram of distribution network GIS power grid

Abstract

The invention discloses a power failure analysis method based on a single line diagram of a distribution network GIS power grid. According to the system of the invention, the InService from the Intergraph Corporation is used as the basic development platform; the data of the currently-operated GIS system is subjected to certain processing to be synchronized to the database of the InService at a certain time to allow the InService platform to use the data; the graphic data in the GIS is converted into map files and the single line diagram of the distribution network GIS power grid which can be recognized by the InService; the data synchronization mode is timing synchronization based on rules; an intermediate server is required in the overall data migration process to be used as transfer of the GIS data; and the model of the GIS data in the intermediate server needs to be correspondingly corrected and modified to enable the GIS data model to satisfy the related requirements of the data migration from the GIS data to the InService and to generate the single line diagram of the distribution network GIS power grid. The power failure analysis method based on the single line diagram of the distribution network GIS power grid has the advantages of saving rush-repairing resource of power failure, accurate fault positioning, reasonable fault isolation, high working efficiency, and high power-supply reliability.

Description

technical field [0001] The invention belongs to the technical field of power failure analysis of a GIS single-line diagram of a distribution network. Background technique [0002] Driven by economic development in recent years, the power distribution network has developed very fast. However, the operating conditions of the distribution network are complex, and the operation is affected by various factors. Therefore, power outages due to faults are more common. When a power outage occurs, the power supply enterprises mainly record, analyze and process the power outage manually, which makes it unintuitive to view the power outage event, wastes resources for power outage repair, low fault location accuracy, and unreasonable fault isolation. The work efficiency is low. Therefore, there is an urgent need for an effective technical means to conveniently and intuitively, timely and accurately conduct power outage analysis, fault merging, fault location, fault isolation, fault occur...

[0002] Driven by economic development in recent years, the power distribution network has developed very fast. However, the operating conditions of the distribution network are complex, and the operation is affected by various factors. Therefore, power outages due to faults are more common. When a power outage occurs, the power supply enterprises mainly record, analyze and process the power outage manually, which makes it unintuitive to view the power outage event, wastes resources for power outage repair, low fault location accuracy, and unreasonable fault isolation. The work efficiency is low. Therefore, there is an urgent need for an effective technical means to conveniently and intuitively, timely and accurately conduct power outage analysis, fault merging, fault location, fault isolation, fault occurrence range and affected user information analysis and processing, and support power outage faults Carry out emergency repairs, improve work efficiency, and improve power supply reliability

[0003] At present, when a power outage occurs due to a distribution network fault, in the power supply enterprise, the customer service of the 95598 call center mainly receives the fault information from the customer and records the information. Whether to merge multiple existing fault reporting information sources, and then perform fault location and dispatch emergency repair personnel to the scene for emergency repair. The main problems are as follows: (1) The fault merging of multiple fault reporting information sources is complicated, the workload of information screening is heavy, and the accuracy of merging is very high for people, which may easily lead to incorrect merging, resulting in repeated dispatching of workers and resources. Waste or unable to dispatch workers immediately;

[0004] (2) The accuracy rate of fault location is low, which may easily lead to inaccurate repair locations;

[0005] (3) The fault isolation is poor or unreasonable, so that the power outage range is large, and it is impossible to simulate and analyze the fault isolation effectively, conveniently and intuitively before isolation to obtain a reasonable fault isolation method;

[0006] (4) When a fault occurs, it cannot accurately and intuitively display the affected range of the power outage and the user information affected by the power outage, and cannot provide an effective basis for fault handling decisions;

[0007] (5) Effective information cannot be provided for the fault repair process, the work efficiency is low, and the statistical quality of distribution network repair data indicators is poor;
