Power grid load forewarning management method and system

Abstract

A power grid load forewarning management method includes the following steps: constructing a power grid load forewarning management system, and connecting an automatic data collection device with collection points on a distribution network; inputting electronic map information and extracting power grid load information of the collection points on the corresponding distribution network to generate a power grid load trend map corresponding to address coding; comparing power grid load values on the power grid load trend map corresponding to each address coding with standard values, and outputting forewarning level maps; and giving out maintenance prompts. A power grid load forewarning management system comprises the automatic data collecting device which is connected with an entering unit, wherein an output end of the entering unit is connected with a storing module which is connected with a control module and an analyze module, and the analyze module is connected with an output module. The power grid load forewarning management method and system has the advantages of being capable of collecting power grid load information in real time, fast and convenient in analyzing and processing, low in analyzing and processing difficulty, audio-visual in display, high in working efficiency and accurate in decision.

Description

technical field [0001] The invention relates to a method and system for early warning management of electric network load. Background technique [0002] Excessive grid load will lead to voltage instability, incomplete grid operation, and insufficient power supply capacity. Serious consequences will cause large-scale power outages in the grid, and even lead to grid paralysis. Therefore, real-time monitoring and early warning of grid load is very important. The existing method of monitoring the load of the power grid is as follows: extract the load information of the power grid through manual operation of the data acquisition device installed on the grid collection point, analyze and tabulate after summarization, give early warning by referring to the report, and maintain the power grid according to the early warning information . [0003] The disadvantages of this method of operation are: 1. Due to the manual collection, the collection time is arbitrarily large, it is diffic...

Problems solved by technology

[0003] The disadvantages of this method of operation are: 1. Due to the use of manual collection, the collection time is relatively random, it is difficult to realize real-time monitoring of the load of the power grid, and it is easy to cause omissions and cause accidents in the power grid due to excessive load

2. The process of summary analysis and tabulation after collection is slow, problems are not handled in time, delays often occur, and the best time to maintain the power grid is missed

3. The report is used as the main reference data. The report data is not intuitive, which greatly increases the difficulty of analysis, low work efficiency, and is prone to wrong conclusions and wrong decisions. It cannot solve the problems of the power grid in a timely and correct manner, resulting in serious problems with user reports and on-site conditions. False
