Distribution network power failure range visualization method based on GIS (geographic information system) imaging

Abstract

The invention discloses a distribution network power failure range visualization method based on GIS (geographic information system) imaging. The distribution network power failure range visualization method based on GIS imaging comprises the following steps of acquiring information of distribution network power failure equipment by using a data interface of a distribution automation system and then analyzing codes of a distribution network power failure transformer; acquiring a downstream power-losing electricity meter box based on analysis of a distribution network low-voltage topology model; and establishing a Graphic object of a building by inquiring the coordinate information of the building corresponding to the power-losing electricity meter box and using the coordinate information of the building on the basis of a Flex secondary software developer's kit of a GIS platform of a State Grid Corporation of China so as to draw the outline of a range of the building on a GIS map displaying widget. The distribution network power failure range visualization method provides an imaging support for power failure analysis and power failure repair. Compared with the traditional power failure range displaying method, the distribution network power failure range visualization method based on GIS imaging has the advantages that the shortcoming that a power failure range cannot be acquired visually by a power supply company in a power failure management process is overcome, the power failure range is displayed visually, a power failure region can be accurately positioned in power failure repair operation, the repair efficiency is improved, and the power supplying reliability is improved.

Description

technical field [0001] The invention relates to a visualization method, in particular to a GIS graphical display-based visualization method for a power outage range of a distribution network, which belongs to the technical field of electric power enterprise information systems. Background technique [0002] Outage management is an important business of power supply enterprises, which is related to the safe and reliable operation of the power grid as well as economic and social benefits. As the scale of the power grid continues to increase, the number of equipment increases, and the user's demand for power supply increases, the impact of power outages is also increasing, thus putting forward higher requirements for power outage management. [0003] The analysis of power outage scope is an important part of power outage management. It can not only reflect the impact of power outage events, but also support the development of power outage repair work. [0004] At present, the ...
