Intelligent analysis method for identifying unreasonable power-failure management

Abstract

The invention discloses an intelligent analysis method for identifying unreasonable power-failure management. The intelligent analysis method comprises the steps of (1) establishing a unified full-path power grid equipment library, and taking as unique identification of equipment in the whole network; (2) establishing a power grid full-topological model; (3) establishing an equipment power-failure history library; (4) extracting power-failure equipment and establishing a power-failure analysis model; (5) analyzing a power-failure influence range; (6) identifying whether the equipment suffers from an overlapped power-failure operation or not; (7) identifying a repeated power-failure operation; and (8) forming a power-failure plan analysis report, and forming a power-failure analysis report from the aspects of the power-failure influence range, whether the equipment suffers from the overlapped power-failure or not and whether the equipment suffers from the repeated power-failure or not. By adoption of the intelligent analysis method for identifying the unreasonable power-failure management, through intelligent analysis on a power grid graphical model, the reasonability of power-failure plan working arrangement is accurately formed from transverse and longitudinal dimensions, so that error and omission caused by human subjective judgment are avoided, and accurate identification of a power-failure plan risk evaluation operation is realized.

Description

technical field [0001] The invention relates to the field of power grid operation analysis and control, in particular to an intelligent analysis method for identifying unreasonable power outage management. Background technique [0002] At present, UHV AC / DC power transmission and transformation projects are continuously put into production, the scale of the power grid is expanding year by year, and the structure and operation characteristics of the power grid are becoming more and more complex. The ultra-large-scale power system and ultra-large-scale grid structure bring new risks; distributed new energy grid-connected, wind power photovoltaic, Large-scale centralized access and power market transactions are gradually deepening, the uncertainty of power grid operation is increasing, and the regulation is becoming more and more difficult. At the same time, users have higher and higher requirements for power supply reliability and power supply quality, thus putting forward hig...

Problems solved by technology

However, with the rapid development of the power grid, the method of manually compiling power outage plans can no longer meet the needs of safe, economical and reliable operation of the power grid. The level of cooperation between power grids at all levels is poor, and many problems have been exposed in the power outage planning work. Unreasonable power outages often occur
