Abstract

Accident processing is the most important link of the scheduling of daily monitoring. The improvement of intelligent level is of great significance for improving the efficiency of accident processing scheduling, shortening the time of accident processing and preventing further deterioration of accidents. According to features of accident processing scheduling, this paper puts forward an integrated framework of aid decision-making of online accident processing based on large power grid, and carries out a study from five aspects, namely integrated information support platform, risk perception in advance, online fault diagnosis, aid decision-making afterwards and visual display, so as to conduct real-time tracking on operating state of power grid, eliminate potential safety hazards of power grid and upgrade power grid from “manual analysis” scheduling to “intelligent analysis” scheduling.

Highlights

  • With the constant reform and development of smart grid system, the traditional grid operation and management mode has been unable to satisfy the development requirements of current smart grid

  • Numerous problems need to be solved so as to prevent power outage of large areas caused by grid accidents

  • From the perspective of safe operation of power grid, it is necessary to collect real-time data of grid operating state and conduct analysis on the data so as to ensure the safe state of data and the reliable and safe operation of power grid. This is an important guarantee for the prevention of power outage of large areas caused by grid accidents

Summary

INTRODUCTION

With the constant reform and development of smart grid system, the traditional grid operation and management mode has been unable to satisfy the development requirements of current smart grid. From the perspective of safe operation of power grid, it is necessary to collect real-time data of grid operating state and conduct analysis on the data so as to ensure the safe state of data and the reliable and safe operation of power grid This is an important guarantee for the prevention of power outage of large areas caused by grid accidents. This paper mainly proposes a study on the auxiliary optimization technology of power grid accident treatment based on the mode of regulation and control integration with the combination of the development status of power companies in Henan province. Static security data of power grid is analyzed when the grid is in safe mode so as to find out weak links of power grid and put forward preventive suggestions for adjustment
