Method and system for analyzing probability of power grid equipment faults caused by various natural disasters

Abstract

The invention relates to a method and system for analyzing the probability of power grid equipment faults caused by various natural disasters, and the method comprises the fault probability calculation of rainstorm disasters, gale disasters, icing disasters and lightning disasters. According to the method, the typical external disasters in Xishuangbanna area is grasped, various warning information, and external information such as weather and disaster prediction and actual measurement are comprehensively analyzed; and information such as the probability of failure, the space-time range and the type of equipment faults caused by disasters is comprehensively analyzed and judged in combination, so that the perceptual ability of regional power grid dispatching operation personnel on the external environment information and the influence thereof is improved, the influence on each region after the power grid equipment suffers from a disaster is reduced, and the risk is reduced to the minimum.

Description

technical field [0001] The invention relates to the field of early warning of equipment disasters, in particular to a system and method for assessing the failure probability of power grid equipment caused by various natural disasters. Background technique [0002] The Xishuangbanna area is hot and rainy in the rainy season, dry in the dry season, and has complex terrain conditions. Strong winds, wildfires, rainstorms, lightning, floods, and geological disasters occur frequently, seriously threatening the operation of the power grid. At present, the dispatch automation system in this area is mainly based on the monitoring and analysis of the power grid's own working conditions. It is difficult for dispatchers to perceive the external environment and analyze its impact on the power grid, and it is difficult to predict and formulate reasonable operation and maintenance methods under severe weather conditions. . In the domestic and foreign research, most of the common disasters...

Problems solved by technology

At present, the dispatching automation system in this area is mainly based on the monitoring and analysis of the working conditions of the power grid itself. It is difficult for dispatchers to perceive the external environment and analyze its impact on the power grid, and it is difficult to predict and formulate reasonable operation and maintenance methods under severe weather conditions.

In the domestic and foreign research, most of the common disasters such as lightning, icing, and typhoon affect the power grid above the provincial level, and there are few studies on the monitoring and impact analysis methods of frequent rainstorms, geological disasters and other disasters in this region, and the lack of regional power grid characteristics Research on Disaster Prevention and Emergency Decision-Making Technology
