Real Time Assessment and Early Warning of Pollution Flashover and Wind Deflection Risk of UHV Transmission Lines Based on Meteorological Factors
摘要
Abstract
Due to the fact that UHV transmission lines have long distance and can be easily influenced by different meteorological conditions, it is of great significance to have a real-time assessment and early warning of the electrical reliability of UHV transmission lines under different meteorological conditions in order to ensure the stable and reliable operation of power system.This paper analyzes the mechanism of transmission line pollution flashover and wind deflection flashover, and introduces the meteorological parameters into real-time assessment and early warning of the electrical reliability of UHV transmission lines. With consideration of the numerical weather forcasting results for the next 1-72 hours, a real-time assessment and early warning model of UHV transmission line flashover and wind deflection risks is established based on meteorological parameters, which can predict the pollution flashover and wind deflection flashover voltage of transmission lines under different meteorological conditions and give early warnings based on their risk levels, realize the risk assessment and warning.关键词
