Statistical Analysis of Meteorological Disasters in the Jiangsu Power Grid and Prevention Methods

Abstract

With the obvious global climate change and the rapid development of an industrial economy in Jiangsu, the number of failures in power equipment caused by meteorological disasters has been increasing every year, especially contamination flashover faults and wind deflection faults. Based on extensive investigation and analysis, this paper conducts a statistical analysis of the temporal and spatial distribution of the typical meteorological conditions in the Jiangsu area. This paper also analyses the effects of the main meteorological disasters and defensive measures that have been taken to prevent them in recent years, and the paper summarizes the characteristics of the faults in a typical case. Finally, the paper gives some overall advice for preventative measures from the perspective of design planning, applications of new technology, disaster warnings and so on. These recommendations may provide an important reference for the design, maintenance and accident prevention for power grids that experience similar meteorological disasters.
