Description
Technical Field
The invention relates to the technical field of meteorological disaster monitoring, in particular to a power grid micro-meteorological disaster monitoring and early warning system and an early warning method thereof.
Background
The power industry is a weather high-sensitivity and high-demand industry, and the production, construction and operation of the power industry are greatly influenced by environmental weather factors. Microclimate refers to the change of small-range meteorological elements (meteorological elements include temperature, humidity, wind speed and direction, air pressure, rain and snow amount and the like) in the near-ground atmosphere and the upper soil layer caused by some structural characteristics (such as microtopography), and the small-range meteorological elements are characterized in individual weather phenomena (such as wind, fog, frost, rime and the like), but the change of the elements cannot cause the climate characteristics determined by a large-scale process (advection and frontal surface) to change greatly.
The transmission line coverage area of China is wide, the transmission distance is long, the terrain of the passing area of the line is complex, the elevation is very different, the meteorological change is obvious, and the microclimate characteristic is prominent. The weather conditions of special terrain areas such as valleys, air ports, rivers, goafs and the like along the line cause the accident potential hazards such as tower collapse, line breakage, hardware wear and the like caused by ice coating, wind deflection, pollution flashover, lightning stroke and the like of the line. The frequently-occurring power grid microclimate disaster accidents show that microclimate, strong wind, rainstorm, pollution flashover, lightning stroke, ice coating and other meteorological disasters and secondary geological disasters in a micro-terrain area seriously threaten the stable operation of a power grid system and cause huge economic loss.
Microclimate refers to the small-scale climatic features in the near-ground atmosphere and in the upper soil due to some structural features of the underlying surface, which are generally expressed in the numerical values of individual weather phenomena (such as wind, fog, frost, rime, etc.). However, the change of the elements does not cause great change of weather and climate characteristics determined by a large-scale process (advection and frontal surface), and microclimate disaster events bring serious influence to the power grid, and may cause the conditions of tripping of power transmission and distribution lines, circuit damage, interphase flashings, conductor waving, broken line tower collapse, damage and interruption of communication transmission networks and the like, so that the detection and early warning of microclimate are made to have important significance for the normal use of the power grid.
