GIS space service based distribution network power supply capacity real-time analysis method

Abstract

The invention discloses a GIS space service based distribution network power supply capacity real-time analysis method. The method comprises the steps of real-time power failure data analysis, real-time extra low voltage circuit analysis and real-time heavy overload platform analysis; according to historical power failure data and real-time power failure data, frequent power failure analysis is conducted from regional distribution and time distribution, and pre-alarm is conducted on frequent power failure areas and time frames; power failure influence, breakdown repair, distribution network investment and consumer complaint information are associated, and the planned outage schedule rationality, distribution network fault repair efficiency, sensitivity of different areas on power failure and distribution network effectiveness are analyzed; by means of GIS space service, real-time states and analysis results of distribution transform and feeders are displayed on a map. Accordingly, locating and tracking of abnormal distribution transform information and image display of the regional abnormal degree are achieved, auxiliary correlation analysis is conducted on abnormal areas and all related factors, distribution network power supply capacity influence factors are deeply analyzed, and the decision basis is provided for distribution network transformation.

Description

technical field [0001] The invention relates to the technical field of power grid security, in particular to a method for real-time analysis of distribution network power supply capacity based on GIS space services. Background technique [0002] With the increasing development of urban power distribution network and the deepening of urban network reconstruction projects, the structure of my country's power distribution network is becoming more and more complex, and the management area is also increasing. However, most of the power distribution systems have relatively weak grid structures, and the construction quality and operation and maintenance level are uneven, resulting in a relatively prominent contradiction between the power supply capacity of the distribution network and the level of electricity demand. In some areas, especially in the urban-rural fringe areas, the phenomenon of overloading of distribution transformers is still serious. Power supply "stuck", frequent ...

Problems solved by technology

However, most of the grid structures of power distribution systems are relatively weak, and the construction quality and operation and maintenance level are uneven, resulting in a relatively prominent contradiction between the power supply capacity of the distribution network and the level of electricity demand.

In some areas, especially in the urban-rural fringe areas, the phenomenon of overloading of distribution transformers is still serious. Power supply "stuck", frequent power outages, low voltage and emergency repair services are still the focus of customer complaints, which restrict the company's distribution network management and distribution network power supply. Improvement of capacity and power supply service quality
