Real-time investigation and early warning method of power grid equipment outage reasons based on n-1 criterion

Abstract

The invention relates to a method of real-time troubleshooting and early warning for shutdown reasons of power grid equipment based on an N-1 principle. The method comprises the following steps of establishing of basic data, statistic of the number of interconnection links of the power grid equipment, troubleshooting of the shutdown power grid equipment, analysis of the shutdown reasons of the equipment, N-1 scanning and analysis, and real-time early warning notifying. The method of the real-time troubleshooting and early warning for the shutdown reasons of the power grid equipment based on the N-1 principle has the advantages that the steps are concise and clear, the defects of failure of real-time troubleshooting of the shutdown equipment and failure of timely analysis and early warning of a power grid in the power grid overhauling process or equipment fault occurrence process are effectively overcome, the stable running of the power grid is guaranteed, and the user is guaranteed to obtain the continuous power supply meeting the quality requirement; the shutdown equipment caused by the fault tripping can be troubleshot in the actual operation process, the analysis and early warning and the quick response can be performed, and an operation analysis person of the power grid can control the first time from a global perspective, so as to avoid the larger influence on the integral safety running on the power grid caused by the shutdown of the power grid equipment.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a method for real-time investigation and early warning of power grid equipment outage causes based on the N-1 rule. Background technique [0002] The grid N-1 criterion is an index used to determine the safe operation of the grid. It mainly includes two meanings. One is to ensure the stability of the grid, and the other is to ensure that users receive continuous power supply that meets quality requirements. When some equipment in the power grid is under maintenance, the power grid is naturally in "N-1" or even more serious state. With the continuous growth of the power grid, equipment is being overhauled all the time, so the N-1 analysis of the real-time running power grid can effectively identify potential safety hazards and weak links in the power grid operation. [0003] The reasons for power grid operation equipment outage mainly include power outage maintenance and faul...
