Method and apparatus for short-term and imminent war of typhoon wind and waterlogging disaster on transmission and distribution line

Abstract

A method and apparatus for short-term and imminent war of typhoon wind and waterlogging disaster on transmission and distribution line At first, that short-term wind field and precipitation information of Doppler radar are obtain, Based on the wind and precipitation information and the typhoon risk assessment model, the short-term and imminent early warning of typhoon and waterlogging disaster ontransmission and distribution lines is carried out, Typhoon risk assessment model can directly and fully reveal the law of transmission and distribution line disaster and power equipment damage accident by extracting the characteristic parameters of typhoon wind and waterlogging disaster prediction grid designed beforehand, early warning the typhoon wind and waterlogging disaster of transmission and distribution line and reducing the typhoon wind and waterlogging loss of transmission and distribution line. The invention helps to improve the accuracy of accident prediction before typhoon disaster occurs in the prediction area, improves the early warning level of typhoon flood disaster of transmission and distribution lines, enriches the typhoon disaster early warning reference information of the power grid, and provides guarantee for safe and stable operation of the power grid.

Description

technical field [0001] The invention belongs to the technical field of power grid disaster prevention, and in particular relates to a short-imminent early warning method and device for typhoon and waterlogging disasters on power transmission and distribution lines. Background technique [0002] With global warming and sea level rise, various natural disasters caused by abnormal weather and climate are increasing. Among them, typhoons, due to their frequent occurrence, high intensity, difficult path prediction, wide range of influence, and huge degree of disaster, caused great damage to the affected area. The power system is a huge and complex system involving multiple links such as generation, transmission, transformation, distribution, and use. Its safe operation is closely related to the meteorological environment. Among them, power transmission and distribution lines are the main objects that are vulnerable to typhoon strong winds. Statistics show that accidents on trans...

Problems solved by technology

[0003] In order to fight against the typhoon, the coastal provinces and cities have carried out typhoon emergency warnings to varying degrees, and obtained meteorological forecast information such as typhoon track, ten-level wind circle, and heavy rainfall forecast through public weather services. The city’s transmission and distribution networks lack real-time monitoring capabilities for typhoon and flood disasters to varying degrees, and due to the lack of effective monitoring methods for strong winds and heavy precipitation as well as sophisticated key data for early warning and forecasting, there are certain limitations in the ability to respond to typhoon, wind and flood disasters and emergency response to accidents. bottleneck

Although meteorological agencies have initially acquired relatively accurate typhoon track warning capabilities in terms of typhoon early warning and forecasting technology through years of development and upgrading, the typhoon track early warning technology developed by meteorological agencies cannot intuitively and fully reveal the damage of power transmission and distribution lines and the impact of power transmission and distribution lines. The law of equipment damage accidents, wind and flood disasters on transmission and distribution lines have serious losses
