Problems solved by technology

[0003] The current lightning location system can monitor and collect current lightning strike information in time, but cannot reflect the impact of lightning strikes on the current power grid, and cannot make accurate and effective early warnings of lightning weather and lightning fall areas in advance, resulting in failure to do a good job in time when lightning disasters come. Early protection of power equipment may cause great harm to power facilities or grid equipment, affecting normal power supply

Abstract

The invention discloses a power-grid-GIS-based lightning analysis and early warning method and a system thereof. The method comprises the following steps that: a basic power grid equipment geological information graph layer is established according to the coordinate of the power grid equipment; real-time monitoring data of lightning weather of the power grid equipment coverage area as well as meteorological cloud atlas data are obtained; a lightning weather data model is established; and the real-time monitoring data and the lightning weather data model are matched, a lightning early warning grade is determined, the basic power grid equipment geological information graph layer and the lightning weather chart layer are associated, and the power grid equipment information and lightning early warning data are overlapped and displayed on the power grid GIS platform. The method and system have the following beneficial effects: the lightning falling area is analyzed and a professional power lightning disaster early warning model is established; power equipment is associated; and precise early warning for the single line and equipment is realized. Targeted measures and specifications for geological disaster prevention can be formulated; and the losses of the power grid can be reduced.

Description

technical field [0001] The invention belongs to the field of meteorological early warning of power systems, and in particular relates to a lightning analysis and early warning method and system based on a power grid GIS. Background technique [0002] Lightning is an instantaneous discharge phenomenon in nature, accompanied by thunder, which has the characteristics of high current, high voltage, fast change, short discharge time, strong radiation, etc. Lightning has strong destructive power on power facilities and electrical equipment. , Lightning disasters test the safety of power grid equipment. July enters the rainy season, and the lightning activity is strong, which is the season of high incidence of lightning tripping of power equipment. [0003] The current lightning location system can monitor and collect current lightning strike information in time, but it cannot reflect the impact of lightning strikes on the current power grid, and cannot make accurate and effective...
